After about two years of sitting on a shelf, I decided to try out my old laptop (2011 Acer Aspire TimelineX 5820TG) and install Windows 10 on it. Turns out, the battery doesn't work properly anymore.
When I turned it on the first time (while plugged in), it said 0% charged. It never got above 0% while turned on, which was about 2 hours. When I unplugged it, it shut down immediately.
Then later that day, after having it charge the whole day (while the laptop was shut down), the charge was 100%. However, when I unplugged it, it still shut down immediately. When I started it back up, the screen started flashing blue and black, and I wasn't able to log in to the laptop, so I had to do a system restore.
Now I've read online that there are multiple explanations, the first being that the battery is busted, and the second that the BIOS is outdated. The problem being, that the Acer supported software that updates BIOS costs money, and so does buying a new battery. So before I spend money on this, I want to know for sure that it's going to fix the problem
How can I tell which is the actual problem?
