To determine if the computer’s keyboard is functioning properly, perform the following
procedures. Start with Procedure 1 and continue with the other procedures as instructed.

board may be damaged. Go to Procedure 2.

Execute the Keyboard Test in the Diagnostic Program. Refer to Chapter 3, Tests and
Diagnostics for more information on how to perform the test program.
