I have a laptop that I got for free. I was told that it stopped taking a charge. I plugged it in to see if it would turn on the light to see if it had a low battery or something but no light turns on. when you press the power button nothing happens either. I was going to get a new battery but before I go spending money I'd like to know all the possibilities of what could be wrong. I'm more of a desktop guy so laptops are new for me
