I don't know any of the background processes but there's nothing actively running in the task manager that I don't recognize.

How old is your laptop?
Polymorph
January 2021.
Dingodile
Have you looked up your problem on Google?
Polymorph
I don't know what I would look up without spending like 50 words on it.
Dingodile
Is the computer displaying an error code when it does this?
Polymorph
Nope. It just throws an error sound, shows the spinning doot for like a quarter of a second, and then turns off.
Dingodile
Assuming you have light indicators on your laptop, have you seen them doing anything when this happens (flashing, different color than normal)?
Polymorph
I have no light indicators.
Dingodile
Is your battery fully charged? Does it drain quickly when you're using it?
Polymorph
It only does this when it's plugged in and it has a totally normal battery life when it's not.
Dingodile
Charger or dock to a bigger screen?
Polymorph
Charger.
Dingodile
How old is the charger, did it come with the laptop?
Polymorph
I think so? I'm not the one who bought the laptop so I'm assuming it came with it.
Dingodile
Do you have a spare one? Maybe you could change the charger. I don't have a Windows laptop, so this is as far as I can help you.
Polymorph
I only have this charger so I can't change it out.
Dingodile
Ah. I've done all I can to help, I'm sorry. I would suggest though getting a new charger and seeing if that was the problem. Hopefully those are cheap.
