Normally, the only test routine visible on the screen will be the
memory test.
Two classifications of malfunctions can be detected during the POST:
¾ ¾ 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.
¾ ¾ 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.
General Hardware Problems
A few common hardware problems and suggested solutions are
presented in the table below:
Problem: Failure in the installation of the Audio driver.
Solution: Be sure to first remove the current audio device
from your system. Please follow the instruction on the
installation of audio driver.
Problem: The display screen is dark
Solution: Make sure that the computer is not in Suspend
mode. Check the Brightness controls for the screen. If the
controls are turned too far down, the screen will be dark.
