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.
General Hardware Problems
A few common hardware problems and suggested solutions are presented in the table below:
Failure in the installation of the Audio driver.
Be sure to first remove the current audio device from your system. Please follow
the instruction on the installation of audio driver.
The display screen is dark
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.
An incorrect date and time are displayed.
Correct the date and time using the DOS DATE and TIME commands or the
options in the Setup Utility. If the date and time become incorrect after a short time, your
CMOS battery may be depleted. Contact your dealer to change the battery.
The message: “Invalid system disk, Replace the disk, and then press any key”
appears during boot.
