Question PC sometimes shuts down instead of waking from sleep ?

[ohm-ish]

Hi
My computer sleep has started acting up.
I often use sleep, when I don't need to use my computer some time. I only shut it down over night
(it's a desktop with latest 64-bit windows 11, all updates installed)

Lately this happens a lot but not always:
Often when I return and try to wake up the computer from sleep, it shuts down instead of waking up.
Other times (rare, but it happens) I come back to a "sleeping" computer where the fans are spinning and it's hot to the touch, and it doesn't respond so I have to hard-reset it.

Could it be some recent windows update that messed with how my computer sleeps?
Or am I malware'd by some crypto farmer?
I doubt it but the thought crossed my mind

How can I know what's happening?

Why do you bother sleeping it or shutting it down? My PCs are left running 24x7 and I've done that with every PC for the last 30 years at least. There's no need to sleep/shutdown really, unless for noise reasons. Modern PCs are best left running.

I think we're going to need more data, so please download the SysnativeBSODCollectionApp and save it to the Desktop. Then run it and upload the resulting zip file to a cloud service with a link to it here. I appreciate that you're not getting BSODs but the SysnativeBSODCollectionApp collects all the troubleshooting data we're likely to need. It DOES NOT collect any personally identifying data. It's used by several highly respected Windows help forums (including this one). I'm a senior BSOD analyst on the Sysnative forum where this tool came from, so I know it to be safe.

You can of course look at what's in the zip file before you upload it, most of the files are txt files. Please don't change or delete anything though. If you want a description of what each file contains you'll find that here.

As another way to help figure out what may be happening is to take a look in Reliability History/Monitor and Event Viewer.

Either one or both tools may be capturing some error codes, warnings, and even informational events that occur just before at the times of unwanted system behaviors.

Reliability History/Monitor provides a timeline format (Days or Weeks View) that may reveal patterns.

I would also check Task Scheduler for any apps etc. being triggered when the computer goes into some sleep or other power saving mode.

Also look into the details about the system's power configuration via "powercfg /list".

FYI:

The results should be similar to but will be different from what my computer presents.

E.g.. (bold font = my computer)

C:\Windows\System32>Powercfg /list

Existing Power Schemes (* Active)
-----------------------------------
Power Scheme GUID: 381b4222-f694-41f0-9685-ff5bb260df2e (Balanced)
Power Scheme GUID: 49ef8fc0-bb7f-488e-b6a0-f1fc77ec649b (Dell)
Power Scheme GUID: 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c (High performance) *
Power Scheme GUID: a1841308-3541-4fab-bc81-f71556f20b4a (Power saver)

If the "powercfg" results are not as expected then the next step is to determine what or how the power configuration settings are being established and run.
