How do you know its the touch pad. it may be just a fuse. that's always the first thing to shut it down.Unplug ! take out the screws to the cover. Look by the power supply and cord. be carefull there is still a lot of juce in there that can zap you.With a pair of plyers pull and replace the fuse. . Basicly this is you can do befor the repair shop. its worth a try. good luck DFD please rate me Tk U
