I'm running a Sony VAIO laptop that will randomly shut down every once in a while - yesterday, after this happened, I turned it on again, only for it to tell me, "OS not found." It turns on and works fine now, but I wish I knew what was going on
Most random shutdowns are caused by either overheating or a faulty power supply. In a laptop it's kind of hard to pinpoint what's happening but you can download some kind of utility that will monitor the internal temp. of the machine. Maybe one of the fans went out our the battery is old & needs to be replaced.
