TP 310,315 - Keyboard Auxiliary Device Checkout
Applicable to: World-Wide
Keyboard and External Input Device Checkout:
Note:
If an external keyboard is attached, remove it if the internal keyboard is to be tested. If the internal keyboard does not work or an unexpected character appears, make sure that the flexible cable extending from the keyboard is correctly seated in the connector on the keyboard connection board on the system board. If the tests do not detect a keyboard problem, run the Keyboard test by doing the following:
1. Boot from the diagnostics diskette and start the PQA program (please refer to "Running PQA Diagnostics Program" on page 30.)
2. Go to the diagnostic menu screen; select Keyboard test and press F2 in the test items.
3. Check that when each key is pressed, the key's position on the keyboard layout on the screen changes to a black square.
Note:
Press Y+Enter to exit the test. If the tests detect a keyboard problem, do the following one at a time to correct the problem.
- Do not replace a non-defective FRU.
- Ensure the keyboard switch is correctly set.
- Reseat the keyboard flexible cables.
- Replace the keyboard connection board.
- Replace the keyboard assembly.
- Replace the system board.
- The following external input devices are supported for this computer:
- Numeric keypad.
- Mouse (PS/2 compatible.)
- Keyboard.
If any of these devices do not work, reseat the cable connector and repeat the failing operation. If the problem is not corrected, replace the device, and then the system board.
