Normally, the only test routine visible on the screen will be the
memory test.
Two classifications of malfunctions can be detected during the
POST:
^ Error messages that indicate a failure with either the
hardware, the software, or the Basic Input/Output System
(BIOS). These critical malfunctions prevent the computer
from operating at all or could cause incorrect and apparent
results. An example of a critical error is microprocessor
malfunction.
^ Messages that furnish important information on the power-
on and boot processes (such as memory status). These
non-critical malfunctions are those that cause incorrect
results that may not be readily apparent. An example of a
non-critical error would be a memory chip failure.
In general, if the POST detects a system board failure (a critical
error), the computer halts and generates a series of beeps. If
failure is detected in an area other than the system board (such as
the display, keyboard, or an adapter card) an error message is
displayed on the screen and testing is stopped. It is important to
remember that the POST does not test all areas of the computer,
only those that allow it to be operational enough to run diagnostic
programs.
If your system does not successfully complete the POST, but
displays a blank screen, emits a series of beeps, or displays an
error code, consult your dealer.
