I have (it's actually not mine, I've just been borrowing it for several months) a Panasonic laptop. It was working fine up until recently. I was using it, then I turned and it off and went to work, and then when I came back home and tried to turn it on to use it, the keyboard wouldn't type! No matter which keys I hit, I cannot get the keyboard to type anything... very occasionally it will catch a letter and it will come up, but that's very occasionally. I really need help with this problem. Does anyone have an advice?
