Recently, my laptop has begun to randomly switch off. I assumed it was overheating, but monitoring the cpu temperatures doesn't seem to indicate this. It stays around or below 50*C in normal usage, which is pretty good I would think.
What else could cause it to switch off like this? It makes a sort of a "beep" noise when it turns off. Dell tech support plainly said "overheating" and are sending someone down since I still have warranty on this, but I'd like to still be prepared for other issues. What other hardware failure could cause this?
