Introduction
If your laptop will not start up or stay charged you may need to replace the battery. It is not a difficult project and the hardest part will be prying the back piece off.
'''***For your safety, discharge your battery below 25% before disassembling your device.'''*** This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair. If your battery is swollen, [[What to do with a swollen battery|take appropriate precautions|new_window=true]].

Shut down and unplug your device before beginning.
