Toshiba TECRA S1 User Manual

Procedure 1    Message Check 
When the power is turned on, the system performs the self-diagnostic Power On Self Test 
(POST) embedded in the BIOS ROM.  The POST tests and initializes each IC on the system 
board. 

 If an error message appears on the display, perform Check 1. 

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

 If there is no error beep code tone out, go to Procedure 3 

 If Toshiba MS-DOS or Toshiba Windows 95/98/NT/2000 is loaded normally, go to 

Procedure 5. 

Check 1 

If the following error message is displayed on the screen, press the F1 key as 
prompted.  These errors occur when the system configuration preserved in the 
RTC memory (generally called CMOS memory) does not match the actual 
configuration or when the data is lost. 

 

If you press the F1 key as prompted by the message, the TSETUP screen 
appears to set the system configuration.  If the error message appears 
frequently when the power is turned on, replace the RTC battery.  If any other 
error message is displayed, perform Check 2.

Check 2 

If the following error message is displayed on the screen, 
press any key as prompted by the message.

lost because the battery has been exhausted or the system board is faulty. 

 

If any other error message displays, perform Check 3 

 

RESUME FAILURE and PRESS ANY KEY TO CONTINUE. 

 
Check   3 

The POST checks the system board.  When the POST detects an error, the 
system stops  
or a error beep code tone out  
or an error POST message appears.
