Fix for Wake after sleep freeze on Dell Latitudes

This turned out to be an issue with the O2Micro SD/MMC drivers on the E6420/E6430 units that we had. After adding new drivers to our MDT server I started getting reports from users stating that their laptops were completely freezing up after waking from sleep - no response to keyboard, mouse, etc.  No mini dumps were generated, powercfg - energy didn't show any major issues, and event viewer was useless.  It was occuring both on Windows 7 and Windows 8.1 builds.

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.

jjcrandall said...

+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.

We'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!

THANK YOU!!

2 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 just saved our agency MONTHS of work with this.

we 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!
DRVR_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...

Vivian said...

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.

You are awesome! Thanks again for posting this!

Vivian said...

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.

Thanks again!

Wooow your the best i was alll oveer the place to find out why its doing this , formatted the computer over 2 times

Please 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.

Gnawgnu said...

Well 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.

Anonymous said...

Thanks! The driver failed to install for some reason. Is it ok to simply disable both items? Aren't they needed for anything?

Gnawgnu said...

They're only used for the SD/MMC card reader on the front. If you don't need it, just disable them.

+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!

I have a Dell Latitude E6420 and O2Micro Integrated MMC/SD controller

Christi said...

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.

Kenneth Brown said...

I 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!

Anonymous said...

Wow 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!

I, also, had success by upgrading to Driver_54WK9_WN_3.0.07.44_A04.EXE through the Dell site found here:

http://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.

I, 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!

Anonymous said...

I 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.

Thanks again!

Anonymous said...

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!

Erik Liljencrantz said...

Yes, 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 :-)

Thanks, Thanks and again thanks!!
I 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,

Luke said...

My experience was slightly different but reaffirms the O2Micro correlation.

I 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 ToolsServices (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.

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..

Gnawgnu said...

I'm sticking with Occam's razor on this one. Try removing your sound driver as well.

I 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.

The 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.

Hello 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.

What 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

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.

I had an issue with several dell latitude e6540 units that would lock up at the unlock screen after resuming from sleep.

They 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!

I 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.

This 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... :-|

Anyone got the O2Micro SD card reader to work reliably in Windows 10 on Latitude E5540 (or similar)?

Erik Liljencrantz said...

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.
Conclusion: 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!)

Windows 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.

Luckily 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!

TheoK said...

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.

For 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.

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

It 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 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.

Thanks for the fix- it was driving me nuts

Tahoe_Jeff said...

I 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!

Thanks dude ! You solved my problem ! I would like to buy you a beer ! 😀

For those of you with a E5550, the A13 BIOS update solved my hibernation issues.

Hi there, really glad I found this!

I 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.

Driver_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.

Thanks a lot - now I have a perfectly working laptop!

Java The Hot said...

Thankyou !!!!!!!!!!!!!!!!!! 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.

You are a genius. thanks again !!

I have version 2.2.1.7068 personally and don't have this problem. My user had version 2.2.2.1038 and experienced this hanging issue when resuming from sleep. I installed a new version 2.2.1.7067 and it worked! Thank you so much.

I 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.
This DELL support link came in handy to upgrade the BIOS firmware on a NON Windows hard drive partition.
