It wasn't until after I started disabling hardware components in Device Manager that I found a correlation between disabling the O2Micro SD/MMC controllers and it being able to wake from sleep. (I rebooted after each diagnostic test just to make sure all changes were in full effect)
Installing an older version of the driver and rebooting fixed the problem on all the laptops that were having the hang issue. Of course, just disabling the SD/MMC controllers is a fine fix too.
Been searching over and over for this fix. Thank you so much for posting. Latitude E6420 and Latitude E6430 with O2Micro integrated MMC/SD Controller with anything higher than driver 2.2.1.7060 seemed to crash laptop after sleep. Bless you.
ReplyDelete+1 for me. I've been having this exact problem for about a couple weeks now, just yesterday I isolated it to these controllers. Ran a google search and found this article.
ReplyDeleteWe're having this issue too, I was disabling devices one at a time and testing after each. I did NOT think of the stupid card reader.... I will try an older driver. Thanks for the post!
ReplyDeleteGood find. THis worked for us too. Saved us a lot of time.
ReplyDeleteDRVR_WIN_R293340.EXE 3.0.07.19,A00 download from Dell works to fix this on Latitude E6420.
ReplyDeleteCool! Sorted the issue we had on a couple of our E6430. Updated with the latest from Dell: Driver_54WK9_WN_3.0.07.44_A04.EXE
ReplyDeletegood one - fixed ours too.
ReplyDeleteTHANK YOU!!
ReplyDelete2 Days of Work with many many installations, updates, drivers and patches did not work for me (E6420, E6430 and E6320!!) Dell Support has no idea either, now i disabled the O2 Card Stuff and all works well!
THANK YOU!!
You are savior man Thanks a lot...!!
ReplyDeleteThank you so much just spent ages in event viewer and device manager, before searching and finding this!!!
ReplyDeletefantastic! i've only had this laptop for 2 days and already the sleep freeze was driving me mental
ReplyDeleteyou just saved our agency MONTHS of work with this.
ReplyDeletewe are deploying Windows 7 to numerous users and have a large range of 6000 series laptops and ran into this early and often in testing.
stumbled onto this blog, and it works right off the bat when the O2 is disabled.
great work!
Confirmed!
ReplyDeleteDRVR_WIN_R293340.EXE 3.0.07.19,A00 download from Dell works to fix this on Latitude E6420
Uninstalled the newer version and installed this older one and voila! E6420 now sleeps/wakes appropriately. Who woulda thought...
Thank you so much! I had thought it was the video driver and had uninstalled and reinstalled that a couple of times to no avail.
ReplyDeleteYou are awesome! Thanks again for posting this!
Thank you so much for posting this! I had originally thought it was the video driver that was causing this but after uninstalling and reinstalling a couple times to no avail, thought I'd give the internet a good look. I downgraded to an older O2Micro Driver and it worked like a charm on an E6420.
ReplyDeleteThanks again!
Wooow your the best i was alll oveer the place to find out why its doing this , formatted the computer over 2 times
ReplyDeletePlease forgive my ignorance. I just inherited this Dell Latitude 6420 from my late brother and there's no one around to teach me how to drive it. I know next to nothing about computers. I found the recommended driver online but I feel unsure about what to do next. Do I uninstall the drivers for both of the items circled in your screenshot? Then how does one file replace both? Please don't laugh.
ReplyDeleteWell first, if you downloaded an .exe version of the driver, just run that and it'll dump out the driver into a folder on your hard drive. Then right click each of those O2 items in the pic above and choose Update driver. Then choose Browse my computer and then go point it to where the updated driver files are.
ReplyDeleteThanks! The driver failed to install for some reason. Is it ok to simply disable both items? Aren't they needed for anything?
ReplyDeleteThey're only used for the SD/MMC card reader on the front. If you don't need it, just disable them.
ReplyDeleteGreat, thank you!
ReplyDeleteBookmarking your page...
From our entire IT office, THANK YOU!!
ReplyDeleteWe had this issue on a few Latitude E6220's and E6330's. You helped us figure it out. Great job!
+1! This has been plaguing us for a while as we use a std image for our Dell fleet. It would only occur on rebuilds of E4 20/30 series latitudes, but not affect our new E5 40 series. Going back to 3.0.07.44 on affected units seems to resolve the issue. Thanks again!
ReplyDeleteYour information fixed my problem.
ReplyDeleteI just rolled back the driver to an older working one.
Thank you.
Sweet thanks!!! this fixed my problem. Any word on how Dell is going to address this problem?
ReplyDeleteWow, I went though numerous Dell chats, reinstalls, even went as far as replacing HDD's because of this issues.
ReplyDeleteOn behalf of our entire IT department, thanks for this!
+1, yes thank you very much for this post. Tried increasing page file size, updating and rolling back video card drivers and messing with the power options all in different ways.
ReplyDeleteI have a Dell Latitude E6420 and O2Micro Integrated MMC/SD controller
version 2.2.2.1038. Once I disabled this device in Device Manager, hibernate works like it should.
Thank you! Thank you! We've been trying to figure this out for weeks! We knew it had to be a bad driver update, but which one? O2 Micro!! Our E-series Latitudes can takes naps again.
ReplyDeleteI have to thank you as well for sharing this solution. I have had 4 Dell E6320 laptops suffering from sleep deprivation and this same issue;) I have used the Windows install media vs SCCM/MDT images to re-image 2/4 machines prior to seeing this fix. What a save, thanks again!
ReplyDeleteWow thank you! Works for e6520 as well. All other results were essential dead ends. I updated with latest driver from the Dell and its working!
ReplyDeleteThanks! Saved me a lot of time.
ReplyDeleteI, also, had success by upgrading to Driver_54WK9_WN_3.0.07.44_A04.EXE through the Dell site found here:
ReplyDeletehttp://www.dell.com/support/drivers/us/en/19/driverdetails?driverid=54WK9#
FYI--the driver below is compatible with both M4700 as well as E6x30 systems.
I did have to repair the driver installation on at least 3 of my laptops before I could resolve the sleep/hibernate issue, as well as use my SD card reader again.
***To repair the new driver, relaunch the chipset driver file you just used for the update and it will ask if you want to repair or remove the driver. Choose "Repair". You should now be all set.
Awesome, thanks so much saved tons of time and works like a charm.
ReplyDeleteThanks for the help. I have been working tirelessly on this issue with e5000 series laptops. Then saw your post regarding the 02Micro drivers and was able to work like a charm afterwards.
ReplyDeleteThis was a great find. Thank you for posting,
ReplyDeleteI, too, just wanted to say thanks very much for posting this information. I was going nuts trying to find the cause of my hibernation problem and this took care of it right away!
ReplyDeleteI forgot to mention, just disabling the O2 SD card slot controller did not solve my hibernate problem. I later went back in and found two services that were also still running: O2FLASH and O2SDIOAssist. Diabling these two services restored my sytem's ability to hibernate.
ReplyDeleteThanks again!
Thanks a lot, this worked for us on an MDT provisioned Latitude E5520. We installed the most recent O2 Micro drivers manually and the problem is gone!
ReplyDeleteYes, on E5520 with new Win7 installation both sleep and hibernate failed to wake up, after installing the latest O2 driver from Dell Support both works. Excellent :-)
ReplyDeleteJust Want to THANK YOU for this find. You just saved me a lot of time and energy by posting this. I work at a company and I just updated too many users laptops and they all started doing that. I spent a lot of time trying to figure this out. Thanks again.
ReplyDeleteThanks, Thanks and again thanks!!
ReplyDeleteI had this same problem on my Dell Precision M4700 after driver updates using the software slimdriverfree.
FYI I running on Windows7 64bit.
I didn’t disable the device in device manager, just clicked on the button that bring driver to a previous driver version (2.2.1.7068) and it was fixed.
I don't know the advantage of having the latest driver for this device, so I don’t see a reason to upgrade it?
Thanks again for the wonderful tip of you!
Kind regards,
Guy
Thanks so much, we have been struggling with this for weeks!
ReplyDeleteThanks for this. It was frustrating to troubleshoot.
ReplyDeleteJust updated drivers on my E6520 and the standby/hibernation freeze problem started (never had it before). Your solution worked. THANK YOU!!!
ReplyDeleteTHANKS for this, it was driving me nuts!!
ReplyDeleteThank you! I have been living with the issue for 2 years with my laptop, but when a client's laptop had the issue I had to find the solution! I will be updating my laptop as soon as I get home!
ReplyDeleteJe t'aime.
ReplyDelete3 months on this issue.
It is solved thanks to you.
Dom (French IT)
Version 3.0.07.44, A04 failed on my E6430 too. SD cards also would not load.
ReplyDeleteI rolled back that driver and everything is now OK.
I was going around in circles trying to get this fixed. Thank you too much.
It is really workderfull. thank you very much. I have been with this issue and unable to read SD card for about 5 moths. after I rollback the driver it is resolved. so simple
ReplyDeleteThanks a lot. Worked just fine for my E6420, uninstalled the driver and windows7 put another generic driver. didn't bother to download latest release from dell support.
ReplyDeleteBrilliant! You took a ton of stress off my shoulders. Virtual High Five!
ReplyDeleteGreat, I was living with this problem from last 6 months, I haven't tried it now but so much thanks note from so many people already suggest me that it is the best solution.
ReplyDeleteSolution provided worked for me! It was bothering me once a month on Win7 and almost everyday on Win8.
ReplyDeleteHi there,
ReplyDeleteThank you for your great post!
FYI, turn out to be that now the Dell Latitude Ultrabooks E7240 are having the same symptoms. I will troubleshoot as stated here and see if there are similar causes...
Thank you
JCB.
After upgrading from XP to Win 7 on the Latitude E6420, it would just freeze at the sleep / hibernate screen - this driver fix has worked! The DRVR_WIN_R293340.EXE download from Dell has now fixed this issue. Thanks!
ReplyDeleteThank you worked for me in MDT environment.
ReplyDeleteThumbs up bro. Thanks!
ReplyDeleteLatest driver seems to have solved the issue on my e7440 as well. Thank you very much!
ReplyDeleteThanks for posting! We have 100+ E5520 that work fine and this one that crashes. Changed the driver and it's OK now :)
ReplyDelete+1 thanks you are the best! my E6320 had the issue and installing the latest driver for the card reader did the trick. It was hidden with the chipset drivers on the Dell support page for my laptop.
ReplyDeleteMany thanks! Great work and thanks for sharing!
ReplyDeleteThanks for the heads up! Fixed my issue too!
ReplyDeleteMy experience was slightly different but reaffirms the O2Micro correlation.
ReplyDeleteI have a Dell E6410 and was surprised to find when trying to replicate Gnawgnu's workaround that I hadn't a O2 Micro driver listed in the Device Manager. Indeed the Device Manager didn't even have a 'Device Controllers' heading under which the offending drivers were supposed to be; perhaps this is due to having a different model Latitude as those detailed in the fix, I don't know.
Regardless, as I was poking about the Administrative ToolsServices (Local, Extended Tab), I noticed the following: "O2SDIOAssist" chugging away. I set the service to "Disabled" and rebooted.
Result: No more waking problems from sleep. Also, the 6410's SD card reader still works, i.e., I do notice a Windows Smartcard Reader driver listed in the Device Manager so ostensibly that's doing the duty.
Don't know when or what package installed that 02 Micro software. It doesn't seem to do anything at the moment except for causing major headaches when enabled.
Equipment: Windows 7 Ultimate Version 6.1.7601 on Dell E6410.
Thank you to Gnawgnu for pointing me in the right direction.
You are the man ! solved.
ReplyDeleteWorks great on a LatE6430. Saludos desde Mexico.
This issue is random and not related to O2 drivers, because i have made clean installation with generic SD card driver and it is still freezing randomly, not always..
ReplyDeleteI'm sticking with Occam's razor on this one. Try removing your sound driver as well.
ReplyDeleteTHANK YOU, SIR! I spent hours on the phone with Dell support, had tech. replace video card... etc, I going to call Dell one last time...
ReplyDeleteThanks it worked well.
ReplyDeleteNice find, thank you for sharing!
ReplyDeleteI have a Dell E6430 and have been trying to resolve this issue since my Desktop Support re-imaged my laptop. I've tried numerous things,memory, drivers, reset all power settings, reset bios to defaults, etc. I finally found a forum response that also stated the O2Micro Integrated MMC/SD controller.
ReplyDeleteThe forum stated driver version A04 has the sleep issue and driver A05 doesn't. Funny thing is that when I put in my Service Tag on Dell's web site it states A04 is the latest. I thought I had the latest driver. I did a search and found A05 on Dell's web site. A05 fixed the issue for me.
You are awesome. Been having this issue for the past couple months. Wonder what started it. Any idea if its bundled with other software?
ReplyDeleteThank you a million
Works perfect. Thanks for the fix!
ReplyDeleteThank you very much, been looking for and testing fixes for more than a week, would've have guessed it's the O2 that was causing this!
ReplyDeleteAppreciate it.
Thanks so much!! Disabled device and issue resolved without reboot.. Installed recommended driver and worked great!!
ReplyDeleteHello Gnawnu, (or anybody who can help), I use a Dell Inspiron N5040 Windows 7 Home Basic and however can't find "storage controller" in my device drivers section...some other guy couldn't but was able to fix by disabling "O2SDIOAssist" through Administrative tools and I can't find this there either.
ReplyDeleteWhat does this mean? Don't I have the driver installed? Or do I simply install the latest version and see what happens. Any suggestions please? Everyone here seems to have this resolved but me. I'll appreciate your help. Thanks
Great, thanks.
ReplyDeleteI was also searching for days to find a solution.
Kind regards,
Christoph
Have this issue E6330,E6520 and E6530. Installed the A05 version on a couple of laptops. For some laptops the driver resolved the issue. Some... Others still have the issue.
ReplyDeleteThank you!Im able to get hibernate works on my E6420(win7 64bit)by installing driver from below link:
ReplyDeletehttp://downloads.dell.com/chipset/DRVR_WIN_R300787.EXE
Awesome! Disabled the SD controller on a E6530 and it worked immediately!
ReplyDeleteThanks! you're a big help. This saved me having to ship a spare laptop from Singapore to Japan!
ReplyDeleteDRVR_WIN_R293340.EXE 3.0.07.19,A00 downloaded from the Dell support driver page worked a treat for my Latitude E6420!
ReplyDeleteThank you, its been awhile since i've a researching of this problem, after 6 months, finally WORKS!!!! saludos desde Guatemala.
ReplyDeleteOooooh! Nice work! This has been a major irritation and now it's fixed. God I love smart people who are helpful.
ReplyDeleteYou Sir deserve to be immortalized in Bronze and placed in a Park.
ReplyDeleteSeriously, this was driving me nuts. I upgraded an i5 to core i7-2760QM in an e6420. And then this issue reared its ugly head.
Thank you for sharing the fix.
On top of disabling O2xxx services I need to do one more thing to fix the issue on my Dell E5440 - change BIOS. So I checked BIOS, go in Power Management to enable Block Sleep which will make Performance, 'Rapid Start Technology' not used. After that BIOS change, Sleep feature is no longer available on Windows 7. The issue is solved for 3 months now.
ReplyDeleteI was having same problem I had changed two machine for this problem but problem is solved now after reading this post. Lot of Thanks for being so helpful.
ReplyDeleteMany thanks it is working fine
ReplyDeleteMAN!!! You saved my life. I just bought e6420 i7 laptop and i was so shocked to see that bug. I thought it is something with the hardware but then after searching a lot, i found your post. THANK YOU SO MUCHHHHHH
ReplyDeleteI had an issue with several dell latitude e6540 units that would lock up at the unlock screen after resuming from sleep.
ReplyDeleteThey didn't have the 02 micro driver on them, but this site gave me the idea to check devices.
Disabling/uninstalling the "dell controlvault w/o fingerprint sensor" device fixed it on all of my machines.
hopefully this helps someone else!
Thaaaaaaaaaaaaaaanks!!!
ReplyDeleteAgain, A dell E6320. Cant say thank you enough. Having to shutdown when closing the lid SUCKS!!
ReplyDeleteThank you. This is of great help !!
ReplyDeleteI just installed DRVR_WIN_R293340.EXE 3.0.07.19,A00
and that worked perfectly with my "new" E6420
Thanks. Disabling the devices sorted it for me too.
ReplyDeleteHi thanks for the forum- am an idiot so how do I apply fixes if I cannot wake up the latitude e 6230 in the first place :(
ReplyDeleteBrand new Dell e5550 with the same problems as described here. Thank goodness for Google.
ReplyDeleteWin 7 x64, UEFI mode boot, AHCI mode, aftermarket SSD. I could've been troubleshooting for days if not for this.
I used the drivers are the following link:
http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=5XP29
After uninstalling my existing ones and installing these, Hibernation worked flawlessly.
I am a local IT admin, and we deploy several thousand of the Latitude 6420/6430's I greatly appreciate someone diligent like yourself that has identified the root cause of this issue. Kudos to you sir!
ReplyDeleteBravo! And I add my thanks to many others. After living with this problem for a few months (it was fine until I upgraded the bios and some drivers), I finally took the time to call Dell. 90 minutes of trying and they couldn't find the problem. I asked my tech to put it in their knowledge base.
ReplyDeleteI have an E6430 laptop but can't find the drivers listed. The 2 storage controllers are the Intel Mobile Express Chipset SATA RAID Controller and the Microsoft Storages Spaces Controller. Do you recommend I either disable or replace with a prior version?
ReplyDeleteAwesome!! This saved my hours!..Thanks and Cheers!!
ReplyDeleteThank you so much. Just bought my E6430 and got this problem. Quick and easy fix.
ReplyDeleteThanks for this. I have an E7440, and after disabling the "SDA Standard Compliant SD Host Controller" I can resume from hibernate without issues. It may be solved by updating the drivers too, but as I never use my SD card slot, I'm satisfied with this workaround.
ReplyDeleteThank you!
ReplyDeleteTHANK YOU!! Worked for Latitude E6540
ReplyDeleteHere's the driver I've used: http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=N0X8T
Thank you!!! I was having this problem on my Dell Latitude I rolled back driver to previous version and problem was solved!
ReplyDeleteThis comment has been removed by the author.
ReplyDeleteJust wanted to say thanks for the fix. I was going crazy with that problem. I have a Dell E6420 with Win 7 64 bit. I diabled those two drivers and the sleep mode works great now!!
ReplyDeleteThe same problem with Latitude 7250. I have tried everything. The only solution that helps is to disable both the devices "Control Vault w/Fingerprint Swipe Sensor" and BayHubTech/O2Micro Integrated MMC/SD controller".
ReplyDeletethanx a lot
ReplyDeleteAWESOME!!! Thanks a bunch
ReplyDeleteThanks a lot man it worked on my dell latitude E6520
ReplyDeleteI am so so glad to have found this article. I had installed a driver update tool and it would be simply impossible to know which driver update caused this. Thank you !
ReplyDeleteSame issue with an e7450
ReplyDeleteFix also works for Latitude E6330. Thank you so much.
ReplyDeleteTHANKS A Lot, spent 3 days to solve this problem, some computer experts told to change RAM, v also installed windows, but thanks to you, it solved my problem in a minute.(Professor Nawab Ali, Pakistan)
ReplyDeleteThank you for this post!
ReplyDeleteI encountered this error and before I even took a stab at it I found your site and problem solved.
Thank you!
(Dell Latitude E6530)
Great job. It works also on a Dell latitude E5520. Sleep well computer and no problems with restart.
ReplyDeleteHad this issue with the Latitude E5450 models (freezing/locking up after coming out of sleep mode) and updating to the latest system BIOS from Dell appears to have fixed it.
ReplyDeleteI too had the described issues with my E6430 waking from powersave or sleep mode when docked with a dual display. I tried playing with the O2Micro integrated MMC/SD Controller driver and disabling it in Windows and in the BIOS but it had no effect. My problem was resolved however by updating the video driver. I didn't update to the latest BIOS but that was my next step. I upgraded from 8.15.10.2712 to 10.18.10.4176 and my problem went away.
ReplyDeleteThanks It works for me on Dell Latitude E6420
ReplyDeleteNormally I don't do comments in posts, but I had to do this in this case! Thank you so much! I have an Dell E5520 and I installed windows 8.1 a couple months ago and since then I was having this issue that was making me crazy! Thank you!
ReplyDeleteYou are a life saver, this works on Dell Latitude E6530.
ReplyDeleteI'm just going to echo everyone's comments...You finally put an end to my multi-week struggle. I just got a Dell M6800 and couldn't figureout why log in was stupidly slow despite having a 3.9ghz i7.
ReplyDeleteThis seems to fix the issue for our newest Latitude E7450 as well as older models.
ReplyDeleteWe've been struggling with this since february this year. Srange thing is, the problem disappeared for the last 2-3 months then suddenly reappeared for a couple weeks ago. We always thought it was software related and I've lost count on how many hours I spent in eventvwr on various machines.
Thank you very much, maybe I can finally close the case which is ~200 days over due :)
I have many E7250 at work. Latley this problem is back and i can't solve it. It's not the BayHubTech/O2Micro Integrated MMC/SD controller. Any other ideas?
ReplyDeleteIv tried to Diable most of my drivers and updated Bios, gfx card.
Man you are awesome !!!. We had 90+ laptops with this problem.
ReplyDeleteThank you so much for sharing this solution.
Thank you so much you just saved my mental health !
ReplyDeleteFor the E7250, Changed the video driver to the one that is listed under the E5450. This will fix the crashing problem after undocking the laptop. Here is the link. We had several with that problem. http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=MW8G3&fileId=3465616887&osCode=W764&productCode=latitude-e5450-laptop&languageCode=EN&categoryId=VI
ReplyDeleteThis was helpful, but for me it was the Dell Multi-Touch Touchpad Driver that was causing my E7440s to lock up after waking from sleep. As soon as I uninstalled that driver, the issue stopped. Anyone else notice this?
ReplyDeleteI tried with the gfx driver but it did'nt work either.
ReplyDeleteWe use encrypted drives and the program Dell Data Protection (DDP) Security Tools is causing this problem, when i uninstall it the problem is gone but we must use it ... And it worked a few months ago.
Anyone know what driver DDP has a conflict with?
You are life saver. Thank you!!!
ReplyDeleteChipset_Driver_54WK9_WN_3.0.07.44_A04.EXE works like a charm on an E6530 - thanks so much!!
ReplyDeleteOh my goodness. My IT guy has been trying for weeks to fix my Dell E7450 with this hibernate problem, he tried everything with no solution. I started looking for a fix online and ran across your blog. This did the trick. Just disabled the SD card controller and WALLA, all is fixed. Thank you, thank you, thank you.
ReplyDeletemany thanks to giving this solution... now my laptop working good.
ReplyDeleteDude!! EVEN IN 2015 THIS SUGGESTION STILL WORKS. SPOT ON SIR!!! ETERNALLY GRATEFUL, I WILL HAVE ONE OF MY KIDS NAME ONE OF THEIR KIDS AFTER YOU!!
ReplyDeleteSolution worked for a Dell Latitude E6230 laptop.
Wooow! Thank you a friggin big bunch.
ReplyDeleteTried installing about a million drivers, been reading a hundred forums, restarted my poor computer about six gazillion times, FINALLY I stumbled upon this. Thaaaaaaank you!
I have a Dell Precision M6600, by the way.
disabling SD controller driver fixed the issue as long as user doesn't require then you don't have to spend more time downgrading to a previous version driver.
ReplyDeleteThanks
Jackie
Ontario, CA
Worked for me, too. Crazy!
ReplyDeleteTHANKYOU THANKYOU THANKYOU
ReplyDeleteNever would have guessed at the card reader driver!
Si, Cornwall UK
It works, thanks
ReplyDeleteThanks! It worked!!!! This happened after updating drivers yesterday.
ReplyDeleteThank You Very much, I purchased a Dell Latitude E5420 upgraded to Windows 10 everything worked great, then I discovered it would not wake from sleep. I thought it was Windows 10 causing the problem, and was about to go back to Windows 7 until I just found your solution, I just disabled the SD controller drivers and it wakes fine now. THANK YOU VERY MUCH!!
ReplyDeleteThank You Very much, I had on a couple of our E6430. Updated with the latest from Dell: Driver_54WK9_WN_3.0.07.44_A04.EXE
ReplyDeleteAwesome! Thank you. Hit our organization with e5520's, e5530's, and e5540's.
ReplyDeletethank you very much for this, had used a driver update software, and had the crashing and black screen issue after updates. rolling back the driver instantly fixed this.
ReplyDeleteI have had a same problem with my Dell Latitude xt3. I've done factory reset and updated windows and all drivers and I started having this problem. After fiddling with power options, I found your solution and it worked instantly. I really appreciate your post as others have done. Thank you for resolving this annoying problem.
ReplyDeleteThank you! I bought two of these, thanks twice!
ReplyDeletehad the same issue on a dell latitude E5440 with windows 10 pro, just went to the dell website and downloaded the latest BIOS and install it, works now.
ReplyDeleteBrate ljubim te u kurac spasio si me problema sa kojim e mucim vec mesecima
ReplyDeleteAwesome! Thank you.
ReplyDeleteMy Model is E5430 and the same problem made me crazy but you solved my problem.
Brilliant! Have fixed both my Latitude 6420 laptops - it was the Memory Card Reader Driver update that fixed it for me (http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=N0X8T)
ReplyDeleteHad tried all the Win 7 fixes suggested, to no avail
Thank you
Thanks man ! Been fiddling for two hours now, I suspected a driver problem, but which one ? I was ready to smash the bloody thing... Thank you so much !
ReplyDeleteRegards, G.
thanks!! worked for me. Searched around for a solution for few hours. This one worked!! Mine is a DELL latitude E6220 and had the same problem. Once I disabled the O2Micro Integrated MMC/SD controller, keyboard/mouse work again when woken from sleep. thanks!!!
ReplyDeleteI was this (-) close to going back to Windows 8! Dell Latitude E6330, same issue, would not resume after sleep. This is with all the latest drivers / bios etc! Disabled the O2Micro and retested, voila, all worked fine!
ReplyDeleteThanks so much, 2 years on and still works! can't believe this hasnt been resolved by Dell
It works and on dell latitude e5520!!! Thank you!
ReplyDeleteVery cool fix, thank you...
ReplyDeleteYa it worked on e5430 also. Thank you so much for the post.
ReplyDeleteThis O2Micro card reader (now BayHubTech/O2Micro) have never worked as it should in my Latitude E5540, now upgraded to Windows 10. There is no sleep issues, but the SD card reader either disappear after reading/writing a few files on the SD card and after an unmount it never reappear. I searched for updated drivers, found version 2.2.2.80 dated 2015-12-10 (later than Dell latest 2.2.2.76) but to no avail - still same unreliable operation. Forced to use USB adapter, but it's slow, so slow, and spending money on a USB 3 SD card reader when there is a built in card reader seems... well, maybe I'll do that... :-|
ReplyDeleteAnyone got the O2Micro SD card reader to work reliably in Windows 10 on Latitude E5540 (or similar)?
Shame to give up, SOLVED for E5540 upgraded to Windows 10: finally downloaded the O2Micro driver from Dell again, but only to start setup and when asked to repair or remove, I COMPLETELY REMOVED the O2Micro driver. In the device manager a new SD host item with a subitem SDA Standard Compliant SD Host Controller appeared, apparently using a standard Microsoft driver dated 2006-06-21 (way before Windows 10?!?) but now the SD card reader works in my Latitude E5540 and the "safe removal" in the tray and reinsertion of SD card works as intended.
ReplyDeleteConclusion: while upgrading to Windows 10, the O2Micro driver should have been removed in favour of the built in Microsoft driver...!?!
(reaching about 55 mb/s write speed compared to 14 mb/s using USB 2.0 card reader, yeah!)
thanks men it worked like in a minute thanks a lot men.
ReplyDeleteWindows 10 Pro on a Dell Latitude E7450 and I was getting annoyed with the fact that this new, week old laptop seemed to not be able to sleep/hibernate properly. Would start up from hibernate and it would almost always have rebooted with Windows 10 starting up as though it were off. Sleep was also hit or miss, but mostly worked fine.
ReplyDeleteLuckily I found this post and after rolling back the driver on Device Manager it seems to be working fine. Will update on status if there is an issue, but for now this seems to have fixed it. THANKS!
Was hoping that this was the fix but after a short while I began experiencing the same reboot after hibernate/sleep (primarily hibernate, I believe). Since then there has been a BIOS update and also two important drivers which have been sometimes linked to this issue (elsewhere); the wireless driver and the Bluetooth driver. So far, this seems to have possibly addressed the issue, but who knows as I thought that disabling the O2Micro device had helped.
ReplyDeleteFor those with newer models, I have an E6540, I did not have these items listed in Device Manager. BUT I found and disabled them in Services: 02FLASH and 02SDIOAssist. Problem solved for me after years of this curse.
ReplyDeleteThanks, helped fix my issue.
ReplyDeleteThe guy who discovered this the first time did a great job. It is still helping people.
ReplyDeleteThanks very much, i have been getting trouble on this matter but today the problem has been solved.
ReplyDeleteI apriceate your knowledge and skills on computer troubleshooting and resolving software problems.
... you are a computer wizard...

ReplyDeletei really appreciate your help
Yes, huge thanks and solved a problem that I had for a couple of months. Here is the direct link to the driver on Dell site: http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=N0X8T
ReplyDeleteIt also took a few minutes to install on my laptop with a message about "gathering disk space requirement" or something for a while.
Thank you ... I was so annoyed for many months and tried hundreds of tutorials to fix it ... THANK YOU ... !
ReplyDeleteHey GOOGLE - take the keywords for this issue DELL FREEZE FIX freeze logon after wake up
Been dealing with this for months. My users will be happy now. Thanks for the insight.
ReplyDeleteThank you so much. It's 2016, but we are still using these laptops at my company, and being unable to put my computer to sleep during lunch, meetings, or whenever I was away from my desk was a serious security issue. IT department had no clue what the problem was. This fixed it.
ReplyDeleteThanks, Bro!
ReplyDeleteWas looking for a solution for a week until i found this! Thanks a Mil!
ReplyDeleteThanks for this, also works on E5520 Dell laptop. Just disabled the card reader
ReplyDeleteThanks for the fix- it was driving me nuts
ReplyDeleteI have a Latitude E7270 on win7 with the problem. But no O2 drivers or services, any other ideas? If it sleeps, I can't wake it up with any action, and the power key shuts it down completely. Thank you!
ReplyDeleteThanks dude ! You solved my problem ! I would like to buy you a beer ! 😀
ReplyDeleteFor those of you with a E5550, the A13 BIOS update solved my hibernation issues.
ReplyDeleteHi there, really glad I found this!
ReplyDeleteI bought a re-furb. E5420 just the other day, looks good, works fast and well, BUT - the same freeze after sleep/hibernate issue! Even the clock on the task-bar stops! I did look to disable the O2 card drivers, but found they were not shown on my Device Manager!
The laptop never saw any SD card I inserted either.
So next I tried updating/installing drivers from the Dell product support/ .... /e5420/drivers. I followed the given order of installation, and loaded all recommended drivers, though mostly I'd no idea what they were, but the site did tell me if the driver was older than the one already installed, etc. so I managed ok I think.
The first thing I noticed very early in this process is that the serious overheating on the left side had greatly diminished, undoubtedly some new driver or other!
Anyway, many many hours of installs later I was surprised to see the O2 drivers listed, (though the laptop still didn't see an inserted SD) so I again hit Sleep, then wake - still the big freeze! Then I disabled both the O2s, and voila! Happiness.
Even more good news - I do have an old Expresscard21 card reader adapter, which oddly does work in the 54mm slot on the e5420, and that reads my SD card fine.
working. thanks
ReplyDeleteSir, thank you so much. I have this old Dell Lattitude and this solution has truly pulled a thorn from my side. :-)
ReplyDeletethank you very much! It took me more than 2 hours to find this - right - solution. Thanks!
ReplyDeleteDriver_54WK9_WN_3.0.07.44_A04.EXE driver update from DELL fixes it for me on the Dell Latitude E6420. I wouldn't have known which driver to update without stumbling on your site and reading your blog post and comments.
ReplyDeleteThanks a lot - now I have a perfectly working laptop!
I do appreciate your answer. I couldn't find any answer after one day of searching. wanted to return the laptop if you didn't save me. thank you man.
ReplyDeleteYou magnificent human being. Worked for Dell Latitude E6230. Now just gotta find the working driver. I'm sure someone here has the right one. Thank you!
ReplyDeleteyou made my day. dell latitude xt3.
ReplyDeleteExcellent...its works on E6t430...thanks a lot..
ReplyDeleteThankyou !!!!!!!!!!!!!!!!!! Fixed !! It was driving me maaaaaaadd on my newly aquired Dell E6430. I was messing about with power settings for hours. On return from sleep or hibernate it would lock up the touchpad, keyboard, and attached logitech mouse almost instantly. I disabled the Card reader in device manager for now, and I'll look at updating the drivers later.
ReplyDeleteYou are a genius. thanks again !!

ReplyDeleteYou are a life saver!!!!
ReplyDeleteI had the Dell wakeup issue on the E6420 Model that was on firmware version A05 which was running Ubuntu 16.04 LTS. I upgraded the firmware to A23. Considering I have no Windows partition to boot from and install the *.exe windows firmware update which resolved the wake up issue. My alternative was the Linux rescue iso and the embedded MSDOS emulation aka freedos for windows on Linux rescue CD which facilitated the successful firmware update.
ReplyDeleteThis DELL support link came in handy to upgrade the BIOS firmware on a NON Windows hard drive partition.

ReplyDeleteI was tired of trying many ways to solve none proper drive for SD card reader of my DELL e5430 W10 Pro 64 and freezing of the laptop after suspension- Until I got You the true solution : http://www.dell.com/support/home/mx/es/mxbsdt1/Drivers/DriversDetails?driverId=54WK9
Best Regards,
I know this is an old post, but I have a similar problem with my desktop PC. I Power Off or Restart, the computer goes through the normal shutdown process but never finishes. Screen goes blank but lights & fans stay on. (Everything works fine in Safe Mode.)
ReplyDeleteI discovered (quite by chance) that disabling my VIDEO CARD DRIVER "fixed" the problem, but going back to an older driver didn't fix it, and I can't just not install a video card driver.
Still looking for a solution. :(
