Windows 10: System shuts down unexpectedly after a while in sleep mode after upgrade to Windows 11

Hi, I'm experiencing an issue after upgrading to Windows 11. My laptop shuts down unexpectedly, when it's in sleep mode for a while. Usually the laptop should enter hybernation, however it looks like it fails to do so and shuts down instead. When I turn the laptop back on, it starts fresh with all applications close. When I open Edge it notifies that it closed unexpectedly and offers to re-open previously opened tabs.

:)

 

My new Vista computer sometimes unexpectedly shuts off. Any suggestions?

OK, first complete your system specs, as it will help us diagnose your problem. Second, can you be a bit more descriptive about the "shut off"? Does it go through the windows shut down procedure, or does the power just shut off completely?

Computer shutting down unexpectedly (after upgrade)


Win 7 Desktop upgraded to Win 10 on 25-July. All was well until 9-Aug and 10-Aug when computer has shut down unexpectedly. In Reliability Monitor it shows (Windows) Photos stopped working on both days. Then after the crash the monitor shows Windows was not properly shut down, stopped working and shut down unexpectedly. Related? No changes have been made other than installing a few programs (CCleaner, Speccy) immediately after the upgrade. I did not have this issue when it was on Win 7.

edit: This has happened two more times since I originally posted. Computer was going to sleep but instead of power button being amber, it was unlit. Pressing it restarted the computer and again I saw that Windows was not properly shutdown, stopped working and shut down unexpectedly. I will attach a second dm log file. Also I have updated System Specs to reflect this desktop computer.
