I have a Toshiba Satellite A205 laptop, that started shutting down with no warning several weeks ago. When it first began, it was after long periods of use. Now it turns on and before it can boot up shuts back down. We have blown out all dust with air compressor and then because the bottom of it was getting really hot, figured it was an overheating problem, so we replaced the fan and the thermal grease, still not working. If it is turned on its right side it will turn on and begin to boot up and stays on a little longer. HELP, I need this computer for part time work. :sad:
