I have a Lenovo V570, and the keys started not working unless I press down really hard on them, which sucks when i'm trying to type up a proposal. I replaced the keyboard, but still having the exact same issue. Short of updating the driver, and reseating the cable, can anyone think of any more possible solutions, or causes? All I can think of is that the connection is defective, on the motherboard end since I replaced the keyboard, and since I don't know how to fix a motherboard, short of replacing it, that means It basically can't be fixed.
An external keyboard works fine. I was thinking of just reseating the keyboard connection, but cleaning it first. Any recommendations on what to use to clean it? I was thinking of alcohol. I figure if cleaning and reseating doesn't fix it, then it must be a problem with the connection at the motherboard.
