Display Codes

There are a number of Power On Self Test (POST) tests that are performed after the Beep Code tests. Failure of one or more of these tests will result in a displayed failure code (such as

03044). It is extremely important not to interpret a failure code immediately as a hardware failure. The failure should be confirmed with a clean boot. A clean boot is defined as pressing the reset button after removing all accessories (including additional memory, floppy drive, modems, PC cards, and printers) and providing a reliable power source. Note, make sure the display is adjusted to be visible.

The following tables lists common PC error messages. Not all of these messages will appear on every model of the OmniBook 800.

Table 3 - POST Display Codes

Message

Possible Cause

CLOCK NOT TICKING CORRECTLY

The real time clock is not ticking.

COLOR/MONO SWITCH INCORRECT

The COLOR/MONO switch on the system

 

board is incorrect for the installed

 

hardware.

CMOS CHECKSUM INVALID - RUN SCU

CMOS RAM information has been

 

corrupted and needs to be reinitialized via

 

the System Configuration Utility.

CMOS FAILURE - RUN SCU

CMOS RAM has lost power and needs to

 

be reinitialized via the System

 

Configuration Utility.

FLOPPY CONTROLLER FAILED

The floppy controller failed to respond to

 

the reset command. Power down the

 

system and check all appropriate

 

connections. It the floppy controller

 

continues to fail, you may need to replace

 

it.

FLOPPY DISK TRACK 0 FAILED

The floppy drive cannot read track 0 of

 

the floppy disk in the drive. Try another

 

diskette. If the problem persists, you may

 

need to replace the floppy drive.

FLOPPY INFORMATION INVALID - RUN SCU

The drive parameters stored in CMOS do

 

not match the floppy drives detected in

 

the system.

HARD DISK CONTROLLER ERROR

The hard disk controller failed to respond

 

to the reset command. Possible

 

solutions: 1) Check the drive parameters.

 

2) Power down the system and check all

 

appropriate connections. If the problem

 

persists, you may need to replace the

 

hard disk controller.

HARDWARE INFO DOES NOT MATCH VIDEO

The video adapter type specified in

CARD - RUN SCU

CMOS RAM does not match the installed

 

hardware.

KEYBOARD CONTROLLER FAILURE

The keyboard failed the self-test

 

command. Check to see if the keyboard

 

controller is properly installed. If the

 

problem continues, replace the controller.
