● Restore the system from the Recovery Disc Set that you created or restore the system to its original
factory condition in System Software Requirement Disks (SSRD).
IMPORTANT: Restoring the system will erase all data on the hard drive. Be sure to back up all data les
before running the restore process.
NOTE: For sales information and warranty upgrades (Care Packs), call your local authorized service
provider or dealer.
Helpful hints
If you encounter problems with the computer or software, see this list of general suggestions before taking
fur
ther 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 light on the front of the computer to see if it is blinking red. The blinking lights are error
c
odes that help you diagnose the problem.
● 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
r
emains in suspend mode, shut down the computer by pressing and holding the power button for at least
four seconds, and 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, and then plug it in again. The computer will restart if it
is set to turn 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
sur
e that it is supported on the system.
NOTICE:
When the computer is plugged into an AC power source, there is always voltage applied to the
sys
tem board. You must disconnect the power cord from the power source before opening the computer to
prevent system board or component damage.
Solving general problems
You might be able to easily resolve the general problems described in this section. If a problem persists
and y
ou cannot resolve it yourself or if you feel uncomfortable about performing the operation, contact an
authorized dealer or reseller.
CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system
bo
ard. To reduce the risk of personal injury from electrical shock, hot surfaces, or both, be sure to disconnect
the power cord from the AC outlet and allow the internal system components to cool before touching.
