considering is a clevo, im thinking its a laptop or similar computer?
it sounds like you have some form of keyboard failure..so the cmos battery prolly wont help.. i would try making sure the connections from the keyboard to the motherboard are secure..this might be hard on a laptop though..
if the connections are secure, replacement of the keyboard may be the only option..?
maybe someone more experienced with laptops will recognise your problem better then me, an know of a better fix?
