I don't know, but I've had my laptop for about a year without any problems. But then just recently I've been having OVerheat problems and extreme slow down from the PC, like it's just flat out Nasty. http://img.photobucket.com/albums/v487/darkloki/IMG_04601.jpg this is an image of what my PC is doing, and the bottom of the laptop has flat out melted away, the print is all gone, and the Modem Casing has warped. I currently have a Targus dual fan to attempt to cool this beast down but now I have ot have this thing next to the Air Conditioner Vent in my room to keep it cool in order to run properly. I could cook eggs in the morning off the back of this thing.
