Procedure 2 Connector checking and replacement checking

If any error is detected, perform Procedure 2. The pointing device is operating normally if no error is detected.
Procedure 2 Connector checking and replacement checking
The touch pad is connected to the System board (PJ334) 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 for the disassembly procedure. If the connector has come off, connect firmly and make sure the operation. If there is still an error, go to Procedure 3.
