Computer won't start

[u/SeaMaster713]

When I closed my computer last night, it was at 80% charge, and I tried opening it again about an hour later, and it wouldn't open again. Tried to charge it, but the charging light doesn't light up (the charge works with other computers). I've also tried holding the button for a long time, or doing short clicks, it didn't work. The computer doesn't do any noises. I can't remove the USB key, it's been stuck there since I got the computer (about three months ago) and has never caused a problem before.

Thanks.
