Chapter 6 Technical Reference 

This section outlines the errors that may occur when you operate the system, 

and also gives you the suggestions on solving the problems. 

Topic include: 

 Trouble Shooting for Error Messages 

 Technical Reference 

 

Trouble Shooting for Error Messages 

The following information informs the error messages and troubleshooting.  Please 
adjust your systems according to the messages below.  Make sure all the components 
and connectors are in proper position and firmly attached. If the errors still exist, please 

contact with your distributor for maintenance. 

 

POST BEEP 

Currently there are two kinds of beep codes in BIOS setup.   

 

One indicates that a video error has occurred and the BIOS cannot initialize the 

video screen to display any additional information.  This beep code consists of a 
single long beep followed by three short beeps.  

 

The other indicates that an error has occurred in your DRAM. This beep code 

consists of a constant single long beep. 

 

CMOS BATTERY FAILURE

 

When the CMOS battery is out of work or has run out, the user has to replace it with a 
new battery.
