Keyboard Problems
Fill out the Diagnostics Checklist as you complete these checks.
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 keyboard that works properly 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 documentation supplied with the keyboard for recommended
settings.
Run the Dell Diagnostics— Reboot the computer and run the
Dell Diagnostics. If any of
the tests fail,
contact Dell.
Check for interrupt request conflicts— See "
Resolving Software and Hardware
Incompatibilities."
