Windows 8.1 does not enter Sleep mode

Since a few weeks my computer incorrectly enters Sleep mode from Start->Power menu.

A few weeks ago, in Sleep mode:

1. The power led was blinking
2. Monitor went black
3. After moving mouse monitor turned on and I needed to enter Windows password

Now in Sleep mode:

1. The power led is on all the time
2. Monitor goes black
3. After moving mouse I am back in Windows, not prompted for password

This is a fragment from my motherboard manual:

PLED (System Power LED):
Connect to the power status indicator on the chassis front panel. The LED is on when the system is operating. The LED keeps blinking when the system is in S3 sleep state. The LED is off when the system is in S4 sleep state or powered off (S5).

This means that after pressing Sleep, Windows is not entering S3 sleep state (as it used before), because the led is not blinking.

This problem is not influenced by choosing (in Advanced Power Options) to allow
hybrid mode on or off nor by choosing to allow wake timers on or off. I tested all combinations and it's still not entering Sleep.

If after two hours of doing nothing on the computer I choose the Sleep mode and then after a minute move the mouse, then in the Event Viewer, in the summary of administrative events there is only one event in the "Last hour" column:
Microsoft-Windows-Kernel-Power with eventID 59 and it says that computer entered away mode.

In my Bios there are some settings which may influence the power behavior. They didn't change since long time and I think they are ok:





Is there any way to help figure out why the computer doesn't enter S3 mode anymore? And how to fix it?

 

PC on Windows 10 doesn't enter sleep mode

I have a PC running Windows 10 that refuses to enter sleep mode. When I choose the manual "sleep" option, the computer teases me and acts like it's going to sleep (the fan stops humming for a split second), but then it wakes up immediately and prompts
me to login to Windows again. And the computer never enters sleep mode on its own, no matter how long I leave it idle or what sleep settings I try. I've tried every suggestion I can find online without success. Please help so I can rid myself of this constant
humming - it's torture for a family quarantined in their house all day.
