i know exactly what the prob is, its the dust and crap in the fan, but how do i go about opening my laptop to clean it, i know to remove the lid on the bottom and all screws, then pop the top of the keyboard off then rmove those screws but now what? i need help... the laptop is a Toshiba Satellite a215 s7422, the fans have completly stopped spinning.... so it burns the crap outta my leg, and shuts off due to overheating
