Windows 10: Computers shutting down while in sleep mode

I have multiple users' computers shutting down while they are in sleep mode. Fast Startup is enabled for some of these computers, but not all. They are running Windows 10 & Windows 11. The shutdown can vary, some may lock their computer, walk away, and it shuts down within an hour of entering sleep mode. Other times, it can be a few hours until it shuts down.Any input on why this may be happening suddenly?

computer shuts down in sleep mode

My computer is shutting down in sleep mode. I have contacted Microsoft 3 times and nothing is resolving this issue. We have tried system restore, changing power functions and they actually did a manual upgrade and it's still shutting down. I am
concerned having to turn the computer back on is going to damage the life of the computer. Any other suggestions?

Computer shuts down instead of going in to sleep mode

Since two weeks my Dell laptop is shutting down every time when:

• Closing the laptop
• Pressing the power button short
• Manually via the Start Menu

All these options are set to Sleep Mode and not Shut Down.
