So, I was using my laptop, which is indeed pretty old (Got it in '07). (As soon as I got it I replaced Windows Vista with XP.) Now, all of a sudden the computer powered off. The battery was almost dead when this happened. So, I plugged it in to charge it, and it has been charging for over 6 hours.
Atlas, I went to turn it on, and the power light turns on for a second, then goes off. Nothing ever happens.
I am assuming this is a battery problem, if so how would I go about replacing it? Also, if this could be something else I would be pleased to hear any suggestions. Thanks.
