Someone might be able to help, but long story short, ac adapter fried motherboard. So i bought a new motherboard for the GT70. Identical. Installed the new motherboard, and noticed everything worked fine but most of the keys on the keyboard did not work, or would type the wrong letter. L would type G, backspace would act as an arrow key and so on. Bought a brand new keyboard and installed that. It is doing the exact same thing. Ive looked it up, and tried taking the battery out, holding power button, nothing. Numb Lock, scrn lock, nothing works. Did i perhaps put a cable in backwards on another part of the motherboard? (the keyboard cable is connected right) Any help please??
