Satellite T230/T235 Series Maintenance Manual 22
To determine if the computer’s built-in TouchPad is functioning properly, perform the
following procedures. Figure 2-6 outlines the process. Start with Procedure 1 and continue as
instructed.
Procedure 1: Perform Touchpad test
Procedure 2: Touchpad connection check
Procedure 3: Touchpad replacement check
Procedure 1 Perform Touchpad 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.
