I do not know if it is a hardware or software problem,I am typing and suddenly jumps a key or I am using the pad to move the cursor and jumps to another place.. I keep a key pressed like this "kkkkkkkkkkk" it suddenly stops and keps going.
Please help it seems that for a second everything stops,,and then keeps going... I just bought this laptop I do not know if I should return it...
