i recently bought this laptop a month back. it auto shutdown when the battery was flat, and since i was out, i could only on and charge it back at home.I tried uninstalling the driver and restarting the laptop after that but the same problem still occur. My keys which could not work is m,n,b, space, enter, left alt, left ctrl, left shift, u, y, i, o, p and some keys on the numpad.
