cannot initialize the video screen to display any additional information. This beep code contains a single long
beep followed by three short beeps. The other code indicates that DRAM error has incurred. This beep code
appears a single long beep repeatedly.
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 same as
the old one.
CMOS CHECKSUM ERROR :
When the battery runs weak, CMOS will be corrupted. Check the battery and change a new one when
necessary.
