Helpful hints
If you encounter problems with the computer or software, see the following list of general suggestions before
taking further action:
●
Check that the computer is plugged into a working electrical outlet.
●
Check that the computer is turned on and the white power light is on.
●
Check the power LED on the front of the computer to see if it is ashing red. The ashing lights are error
codes that will help you diagnose the problem. Refer to POST error messages and diagnostic front panel
LEDs and audible codes on page 102 for more information.
●
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.
●
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 (such as a USB device) from the system before turning it on.
●
If you have installed an operating system other than the factory-installed operating system, check to be
sure that it is supported on the system.
CAUTION: When the computer is plugged into an AC power source, there is always voltage applied to the
system board. You must disconnect the power cord from the power source before opening the computer to
prevent system board or component damage.
