Hello everyone. I have 2 Toshiba Satellite laptops, an L500-1xu and L500-1hc. They look identical on outside. The Pro has the motherboard damaged, and I am interested if I can replace it with the one from the simple L500? Are they compatible in terms of motherboards? Or these must be of the same model name, and serial etc? Only then can be replaced? Thanks to the one who knows. Andrew.
