The results are in and my battery is definitely not functioning in my laptop. The problem I face is that my laptop only shuts down when it is overly hot. The only reason it shut down early while it was hot was that I believe my power cord was nudged and it shut down. I left the laptop on all night and it did not shut down, and I had my fan on it so no over heating. So is it worth it to buy a new battery? Will a new battery "most likely" stop my over heating? Or is that something a bad battery just doesn't do?
