    Try clearing the cmos? updating the bios- Does sound like it is a keyboard socket problem - assume you have cleaned and looked for bent /broken pins. I see you have reformatted
    but just check what keyboard the system thinks it has- think a keypress should still give something but worth a quick look
    Please upload pictures using attachment function when ask for help on the repair

      Hello, this is usually caused by the EC ic (made from winbond or ene).

        EC is the second place to look, first place is after connector, caps near connector. there are toons of caps or sometimes group of caps near/under keyboard connector. Compare with schematic if you have. then search for a cold soldered ec leg connected to those caps. Ec gets the keystroke signals by that pins. if everything is ok then replace EC.
