Troubleshooting and Repair

OmniBook Self-Test

The complete self-test procedure is documented in the OmniBook

 

5000 Operating Guide.

 

A note about interpreting self-test results.

 

Self-test alone should not be used to diagnose a hardware problem.

 

If the self-test results are absolutely clear and repeatable, confirm

 

the results with at least two other non-self-test failure symptoms.

 

The OmniBook 5000 BIOS includes a POST facility that tests a

 

number of hardware and firmware items in the unit at each cold-

 

start (BOOT or RESET).

First POST: BEEP CODES

These multiple beep codes indicate a failure in a simple test of:

 

a portion of base memory

 

Flash BIOS checksum

 

a portion of conventional memory

 

a portion of extended memory

 

If the unit fails to boot:

 

All accessories are removed, including memory cards, external

 

floppy, port expander, modems, PCMCIA cards, LAN cards,

 

printers, VGA-out cables, external pointing devices, clean AC power

 

is provided (no "chained" battery chargers or auto adapters), and

 

press reset.

 

If the unit still fails to boot, it requires service.

 

Beep codes

 

Beep codes are used to identify a POST error that occurs when the

 

screen is not available. Once the screen is operating, diagnostic

 

messages are reported to the screen. There are beep codes for

 

both fatal and nonfatal system board errors.
