My laptop is currently experiencing an issue in which it won't turn on unless the charger is plugged in. After researching this, I found that that the most likely cause of the issue is a dead battery. I want to buy a new battery for my laptop, but how do I know which battery to buy? My laptop is an Acer and the model number is MS2253.
