Okay my laptop will not stay on for more then a minute. It DOES say that the battery may need to be replaced because it's low. Well I took the battery out and just plugged the power cord in to the wall. I still get the same problem it will not stay on. If I let it sit for a little while then go turn it on it will stay on for a little longer maybe 3 minutes. Please help. Ok so I just tried to see if it could be overheating because it will shut down when that happens. I put a fan pointed at the bottom of my laptop and it seems to stay on. But before it did not seem like it was getting that hot. Also my battery is still out of it currently. So what should I do.
