I've got an issue. My laptop randomly shuts off. First it would happen and I'd just turn it back on and it would be fine for a while before it happened again, but now it's happening more and more often, sometimes before it even boots up. I've been running it purely off AC power, as I need to get a new battery. My computer guy told me to take the battery out if it's dead, so I did. Could this have anything to do with what's happening? I'm also in a pretty dusty house. Could that mess with the fans or something? It seems like it might be an overheating issue, but if it is, how do I fix it? Is the only solution buying one of those cooling platforms?
