Within POST, there are three kinds of messages:
Error messages: These messages appear when there is a failure in
hardware, software, or firmware.
Informational messages: These messages provide information to the
user but require no action.
Beep codes: This kind of warning sounds when POST errors occur and
the screen is not available.
Because the OmniBook cannot be repaired by a service center below the FRU
level, these messages will provided limited troubleshooting or repair
information. However, the support specialist and service technician will be
able to identify trends in repairs from these codes.
