Identifying Problems
Follow the steps below to identify your problems:
1. Turn off the computer.
2. Disconnect any peripheral devices such as an external mouse or printer.
3. Make sure that the AC adapter is properly connected to your computer and
the power source is good. (Use some other electrical device to confirm that
the electrical outlet is working.)
4. Leave the computer off for approximately 10 seconds, and then switch it on
again. The computer should enter the boot sequence and start normally.
5. If the computer does not start normally, look for a screen message or other
clue on the malfunction.
If failure is detected in an area other than the mainboard, an error message is
displayed on the screen and testing is stopped.
If your system does not successfully start, but displays a blank screen, emits a
series of beeps, or displays an error code, consult your dealer.
General Hardware Problem
A few common hardware problems and suggested solutions are presented
below:
The display screen is dark.
1. Adjust the screen brightness.
2. Make sure that the computer is not in suspend mode.
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. (You can also set the date and time in Windows by
double clicking the clock on the task bar or in the control panel.) If the date and
time become incorrect after a short time, your CMOS battery may be depleted.
Contact your dealer to change the battery.
