Why won't my laptop work unless plugged in?
Hello! My laptop is a couple years old and now it won't stay on unless it's plugged into the charger. I was wondering if anyone knew what the problem was.
Matthew Fajardo, I'd start off with a new battery.
My T520 is beat to !&&* and it is two generations newer than yours. Its battery died two years ago. Your laptop needs a new battery.
I think your first step should be to buy a replacement battery as it sounds like your charger is still working.
Here is a link to the battery replacement guide:
