2 Troubleshooting 2.9 Touch Pad
2.9 Touch Pad
To determine whether the Touch Pad is faulty or not, perform the following procedures:
Procedure 1: Diagnostic Test Program Execution Check
Procedure 2: Connector Check and Cable Check
Procedure 3: Replacement Check
Procedure 1 Diagnostic Test Program Execution Check
Execute the keyboard test program, or maintenance test program, because the pointing device
test program is a component of the keyboard test program. For the operating procedure, see
Chapter 3.
If any error is detected, perform Procedure 2. The pointing device is operating normally if no
error is detected.
Procedure 2 Connector Check and Cable Check
The touch pad is connected to the system board (CN3240) with a flexible cable. This cable
may have come off the connector or the connector may have come off the system board.
Disassemble the computer and check the cable connections. See Chapter 4, Replacement
Procedure for the disassembling. If the connector has come off, connect firmly and make
sure the operation. If there is still an error, go to Procedure 3.
