In short, my PC battery is damaged, and when I check the charge level, it sometimes says 100% when it's not, and it ends up shutting down on its own. Unfortunately, to avoid these instant shutdowns, I have to keep my PC charger plugged in while I'm using it.

I'll just say a few things:

1. If the technicians find a solution to replace the battery, everything will go back to normal.

2. If there's no solution, then I'll have to keep using it plugged in, at least temporarily, if they find an effective fix.

It's not the end of the world, but... dude, my PC is already 3 years old, and I hope it keeps running for a few more years.
