This system cannot work without DIMM memory.
Memory errors might stop system operation, show error
messages on the screen, or hang the system.

Note: Make sure that the DIMM is properly installed into
the connector. A loose connection can cause an
error.

2. Boot from the diagnostics diskette and start the PC
Doctor program (please refer to “Running the PC
Doctor Diagnostics Program” on page 135).

If no error appears, install a new DIMM; if an error
appears, replace the system board.

Doctor program (please refer to “Running the PC
Doctor Diagnostics Program” on page 135).
2. Select Interactive Tests.
3. Select Keyboard.
4. Follow the instructions in the message window.
If the test detects a keyboard problem, do the following
one at a time to correct the problem. Do not replace a non-
defective FRU.
Ensure the keyboard type switch is correctly set. See
“Switch Locations” on page 180.
Reconnect the keyboard flexible cables.
