Question about PC Laptops
No keys on my keyboard work.
This issue is often caused by either a bad keyboard, bad interface board, and/or bad motherboard.
Answer: Disconnect the keyboard from the computer and connect another known working keyboard to it. If this is a PS/2 keyboard and connecting multiple keyboards or a known working keyboard to the computer PS/2 port does not work unfortunately it's likely that the PS/2 port is bad. Because this port is part of the motherboard this will require that you replace the motherboard. Alternatively if replacing the motherboard is too costly or not an effective solution you could also consider using a USB keyboard if USB ports are available on the computer.
Not all keys on keyboard work.
Reference number: CH000305
Not all keys on keyboard work. Issue: Not all keys on keyboard work.
Cause: This issue is often caused by a bad keyboard or software preventing these keys to be pressed.
Additional information: This document contains information about troubleshooting a keyboard that has some functioning keys. If no key on the keyboard is working see document CH000955.
Solution: Verify that the key is not working in more than one application. It is possible that some keys may not be used in all programs. This generally always applies to the Function keys F1 through F12. If not all keys are working in all programs and you have Windows, attempt to boot the computer to a MS-DOS prompt or safe mode and test the keyboard in DOS. Information about getting into safe mode can be found on document CHSFAFE and information on how to boot to DOS can be found on document CHDOS. If it appears that a substance has been spilt into the computer, please review document CH000303. If all above suggestions have been completed or if you are not running Windows, it is likely that the keyboard and/or keys are bad and it is recommended that the keyboard be replaced with a new one.
