I was sitting in class this morning with my laptop out and powered on. I was listening to the lecture when suddenly i heard it click off. The light that indicates it is plugged into an outlet was on. I pressed the power button and the power light flicks on for a split second but the laptop does nothing. There was a burnt odor coming from the laptop. I opened it up later and i don't see anything wrong. I can still smell the burnt odor on the fan but no where else. Is it possible that the fan burnt out and the laptop won't start as a safe guard? Please help! Thanks!
