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 0240).
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 memory cards, external floppy drive, modems,
PCMCIA cards, and printers) and providing a reliable power source.
The following list explains a number of POST Display Codes. Note, not all codes are available
on all models of the OmniBook.
