Lenovo IdeaPad 400 all keyboard not working

My keyboard is not working at all. None key is functional, repeate: none!!!

An external usb keyboard works fine.

Do you think it could be a driver problem or its a hardware problem?

Re: Lenovo IdeaPad 400 all keyboard not working

Hi Rcamatti,


Welcome to the Community Forums.


If the keys (arrow kkeys , enter, caps lock etc) are not working in the BIOS then it is more likely a hardware issue.

You can call in technical support for inwarranty repair else to have it checked with your local service center.
