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 to see that the voltage select switch (some models) is set to the appropriate voltage for your
region (115V or 230V).
●
Check to see that the computer is turned on and the green power light is on.
●
Check to see that the monitor is turned on and the green monitor light is on.
●
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 for more than four seconds, 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 automatic start on power loss is set in Computer Setup. If it does
not restart, press the power button to start the computer.
●
Reconfigure your computer after installing a non–plug and play expansion board or other option.
●
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 (diskette, CD, or USB device) from the system before turning it on.
