Windows 10: How can I make computer sleep until I tell it to awaken, and stay awake until I tell it to...

I need to know How can I make computer sleep until I tell it to awaken, and stay awake until I tell it to sleep? Last night for the zillionth time my computer woke me up in the middle of the night playing music and brightening the room. When I turn it off by putting it to sleep, I want it to stay asleep until I wake it, and when I wake it, I want it to stay awake until I put it to sleep or turn it off. I am using Windows 11

:)

 

easy way to stay awake?

The best way to try and stay awake is to not try and stay awake.
If i try to sleep i don't sleep and vice versa.

 

Windows 10 can't stay awake


My computer won't stay awake either, and once it goes into sleep I cannot get it out of sleep without manual restart, this is really a pain, I updated graphics driver as I saw that as a suggestion but it didn't help. Hoping an update/fix comes soon.

 

Windows 10 can't stay awake


I just upgraded to Windows 10. The jury is still out if I like it better than Windows 7, but I think so. One big problem is nothing I've done will adjust the power setting to keep my laptop from going to sleep. I notice that there is not an option for "dim the screen" I doubt this is why or where I can tell my computer to stay awake, but all other power options won't take hold, meaning, I tell the computer to NEVER sleep and three minutes later, my computer is sleeping. Is this a kink that Windows needs to fix? Is anyone else having this issue?
