I bring my laptop back and forth to school and every so often after removing it from my bag It will not turn on. The only way I can get it to turn on is to fiddle with the battery on the back until it is connected just right. The socket on the battery seems to have small cracks in the plastic where it connects so I am assuming that is the problem and a new battery will stop the issue. Batteries are super expensive however and I literally never use the computer without it connected to a power supply. The problem is that the laptop doesn't seem to turn on even when connected to an outlet unless the battery is connected properly. How can I confirm a battery is needed in order to power on the laptop even if it is plugged in? Any way around getting a new battery if it does normally need one to operate?
I would boot to the BIOS setup screen, then pull the battery. If it shuts off, the battery is needed.
Try this procedure:
If it turns on then it does not need a battery.
If it does not turn on, then I say it is broken but you may interpret is as it needs a battery.
Maybe with the battery semi-connected as you tried, the computer circuitry got confused. Never heard of a laptop absolutely needed a battery.
