2.4 System Board and HDD I/F Board Troubleshooting

This section describes how to determine if the system board and sound board are defective or

not functioning properly. Start with Procedure 1 and continue with the other procedures as

instructed. The procedures described in this section are:

Procedure 1: Message Check

Procedure 2: Printer Port LED Check on Boot Mode

Procedure 3: Printer Port LED Check on Resume Mode

Procedure 4: Diagnostic Test Program Execution Check

Procedure 5: Replacement Check

Procedure 1 Message Check

When the power is turned on, the system performs the Initial Reliability Test (IRT) installed

in the BIOS ROM. The IRT tests and initializes each IC on the system board.

❑ If an error message displays on the screen, perform Check 1.

❑ If there is no error message, go to Procedure 2.

❑ If the Toshiba MS-DOS is properly loaded, go to Procedure 3.

Check 1 If one of the following error messages displays on the screen, press the F1 key as

the message instructs. These errors occur when the system configuration pre-

served in the RTC memory (CMOS type memory) is not the same as the actual

configuration or when the data is lost.

If you press the F1 key as the message instructs, the Setup Screen appears so that

you can set the system configuration. If error message (b) appears often when the

power is turned on, replace the RTC battery. If any other error message displays,

perform Check 2.
