To determine if the computer’s built-in Touchpad is functioning properly, perform the following procedures. Figure 2-7 outlines the process. Start with Procedure 1 and continue as instructed.

Procedure 1

Diagnostic test

Run the Diagnostic Program, which will automatically execute the Touchpad test. (Refer to Chapter 3 system configuration check), Tests and Diagnostics for more information on the program.

If an error is located, go to Procedure 2. If an error is not located, the Touchpad function is functioning properly.

Procedure 2 Touchpad connection check

The Touchpad is connected via the Touchpad FPC to the system board. Make sure the Touchpad FPC cable is firmly connected to the Touchpad and system board. Refer to Chapter 4, Replacement Procedures, for instructions on how to disassemble the computer and then perform the following checks.

If any of the connections are loose, reconnect firmly. If any of the connections is damaged, or there is still an error, go to Procedure 3.

Procedure 3 Touchpad replacement check

The Touchpad unit or FPC may be defective or damaged. Replace each with a new one following the steps in Chapter 4. If the free-Dos test is still not functioning properly, replace the system board with a new one following the steps in Chapter 4.
