Helpful Hints
If you encounter problems with the computer, monitor, or software, see the following list of general
suggestions before taking further action:
●
Check that the computer and monitor are plugged into a working electrical outlet.
●
Check that the voltage select switch (some models) is set to the appropriate voltage for your region
(115V or 230V).
●
Check that the computer is turned on and the green power light is on.
●
Check that the monitor is turned on and the monitor light is on.
●
Listen for beeps from the computer. The beeps are error codes that will help you diagnose the
problem. Refer to
Interpreting POST Audible Codes on page 39
for more information.
●
Turn up the brightness and contrast controls of the monitor if the monitor is dim.
●
Press and hold any key. If the system beeps, then the keyboard should be operating correctly.
●
Check all cable connections for loose connections or incorrect connections.
●
Wake the computer by pressing any key on the keyboard or pressing the power button. If the system
remains in suspend mode, shut down the computer by pressing and holding the power button for
at least four seconds then press the power button again to restart the computer. If the system will
not shut down, unplug the power cord, wait a few seconds, then plug it in again. The computer will
restart if it is set to power on automatically as soon as power is restored in Computer Setup. If it
does not restart, press the power button to start the computer.
●
Reconfigure the computer after installing a non-plug and play expansion board or other option. See
Solving Hardware Installation Problems on page 25
for instructions.
●
Be sure that all the needed device drivers have been installed. For example, if you are using a
printer, you need a driver for that model printer.
●
Remove all bootable media (CD or USB device) from the system before turning it on.
