Keyboard Problems

Fill out the Diagnostics Checklist as you complete these checks.

Restart the computer —

If the mouse is functioning, shut down the computer through the Start menu. After the computer shuts down, press the power button to restart the computer.

If the computer does not respond to a keystroke or the mouse, press the power button for at least 8 to 10 seconds until the computer turns off. Press the power button again to restart the computer.

Check the keyboard cable —

Ensure that the keyboard cable is firmly connected to the computer.

Check the cable connector for bent or broken pins and for damaged or frayed cables. Straighten bent pins.

Remove keyboard extension cables and connect the keyboard directly to the computer.

Test the keyboard — Connect a properly working keyboard to the computer, and try using the keyboard. If the new keyboard works, the original keyboard is faulty.

Check the keyboard switch setting — Switch settings are on the bottom of the keyboard, sometimes behind a panel. Ensure that the switch is set to PS/2, Enhanced XT/AT, or PC/AT. See the keyboard documentation for recommended settings.

Run the Dell Diagnostics — Run the PC-AT Compatible Keyboards tests in the Dell Diagnostics. If any of the diagnostics tests fail, contact Dell.

Check for interrupt request conflicts — See "Resolving Software and Hardware Incompatibilities."
