It crashed last night (from overheating I'm guessing)..and it's not the first time it has done this..It's crashes like 10 times a day..so I just wait 30 seconds and turn it back on. So yeah, it craashed and now I can't turn it back on.. Whenevr I try pressing the on button, a light flashes on the battery sign..so I put the charger in but it still didn't turn on...whats the problem?
