Computer lost saved state upon waking from sleep

Rather occasionally, like around 4-5x a month, when I wake my laptop from sleep, no previously running applications will be running and the desktop is clean as if it was rebooted. There is no BSOD as well.

Any ideas on how to narrow down the issue ? Cheers :)

Edit:
I tried running Driver Verifier as per the tutorial, but upon reboot a BSOD due to iorate.sys occurred. It seems like Driver Verifier didn't get a chance to verify anything

Hi nabbyG.

Could you share what windows version and build you are running?

Any chance that your computer is going from sleep to hibernate and then not waking from hibernation correctly, thus the reboot.

As a test you could shut hibernation off. This will disable Windows Fast Startup but it is just a test.

At a command prompt(admin)

powercfg -h off

to re-enable same command just with the word "On" (no quotes)

Yes. It sleeps so long then to save power it enters the next level of power savings, hibernation.

Some machine don't hibernate well. Not sure why it would start this behaviour but this relentless driver updating processes from Windows could be involved (or not).

That could be.

One other thing to check is what happens when you machine BSOD's. This maybe the failure you don't see. Not saying your machine is BSOD'ing.

I set my machines to not automatically restart after a BSOD. To do this

Press Windows Key +R, type sysdm.cpl, enter, click Advance tab, click on “Setting” in Startup and Recovery section. Remove check mark from “Automatically restart”.

If you have a BSOD you will have to shut down and then power on.


Now the fact that your machine is at the log in screen could also mean it was awakened and not a BSOD. If you login then you can ask Windows who gave the command to wake up. At a command prompt(admin)

powercfg -lastwake

Lots of machines don't sleep as well as they should. Even small vibrations with sensitive mice can issue the wake up call.
