PC seems to power off after being put to sleep

Harsalan · 29 Jun 2022

I've had a minor issue for a while whereby when starting up my PC after sleep, I'd hear the POST beep and see the windows loading screen, although when I got to the lock screen and logged in, my workspace and such were saved (similar to what happens if you put a computer to sleep and it loses power) - this was an interesting quirk but not very annoying.

Recently - perhaps after installing a windows update or perhaps after enabling Hyper-V so I could use WSL2 - when I turn the computer back on, it does a fresh boot. Digging into the Event Viewer logs a bit shows the critical failure:

"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."
and
"The previous system shutdown at 9:49:25 AM on ‎6/‎29/‎2022 was unexpected."

That timestamp, though, isn't associated with any error logs.

When I have to chase a problem and have found an Event viewer entry,
- I run NirSoft FullEventLogView,
- Sort the results into date-time order,
- Find the Event that I had previously found in Event viewer,
- Look at the Events that were recorded just before it.

Best of luck,
Denis

Welcome to TenForums.

It's really worth making time to browse through the Tutorial index - there's a shortcut to it at the top of every page.

- At the foot of the Tutorial index is a shortcut to download it as a spreadsheet.
- I download a new copy each month.
- By downloading it as a spreadsheet I can benefit from Excel's excellent filtering capabilities when I search for topics of interest.

- Tutorials are also listed by category at Tutorials - there's also a shortcut to that at the top of every page.
- Both tutorial lists are searchable.
- You can also search for TenForumsTutorials in many general search engines, such as Google, by adding site:tenforums.com/tutorials after your search term. For example,

I dug a bit more into this, and the immediate change that triggered this issue was enabling Hyper-V via the BIOS so I could use WSL2 - for some reason this disables Hybrid Sleep, which was the feature that had been preventing me from losing my session. Fortunately hibernate still works so I've switched to using that.

I still don't know why my PC loses power when it goes to sleep, though.

1 Does it also happen for a new user account [even if you have to create one for test purposes]? Add Local Account ... - TenForumsTutorials
2 Does it also happen in Safe mode? Boot into Safe Mode - TenForumsTutorials

If the answers are
1 Yes
2 No
then go to the relevant support site for the download then reinstall your display driver. Corrupted display drivers can generate a host of symptoms.
And check for any Bios updates as well.
