Procedure 1 Message Check; Procedure 2 Diagnostic Test Program Execution Check - Toshiba Satellite M500 Maintenance Manual

Procedure 1 Message Check
When the power is turned on, the system performs the Power On Self Test (POST) installed
in the BIOS ROM. The POST tests each IC on the main board and initializes it.
 If an error message is shown on the display, perform Check 1.
 If Toshiba MS-DOS or Windows VISTA(TM) is properly loaded, go to Procedure 2.
If one of the following error messages appears on the screen, press F1 as the
Check 1
message instructs. These errors occur when the system configuration preserved in
the RTC memory (CMOS type memory) is not the same as the actual
configuration or when the data is lost.
Press F1 as the message instructs to return all system settings to their default
values. Then the system reboots. Press F2 to run setup.
If an error message (a) appears often when the power is turned on, replace the
RTC battery. If any other error message displays, perform Check 2.
