I have a Toshiba Satelite 1130-Z24. It was recently dropped from a chair, approx dropped a foot onto the floor. It now does not power up, although when connected to the mains power appears to be getting to it. I have looked all over for a service manuel for this, as I suspect either the motherboard or power supply is damaged, but im not sure how to dismantle it. Can anybody offer any advice, or assisstance.
