Display problems

When I turn on the

computer, nothing appears

on the screen.

• If the screen is blank, make sure that:

- The AC adapter is connected to the computer and

the power cord is plugged into a working electrical

outlet.

- The computer power is on. (Press the power button

again for confirmation.)

• If these items are properly set, and the screen remains

blank, have the computer serviced.

When I turn on the

computer, only a white

cursor appears on a blank

screen.

• Restore backed-up files to your Windows

environment or the entire contents of your hard disk

to the original factory contents using OneKey

Recovery system. If you still see only the cursor on

the screen, have the computer serviced.

My screen goes blank while

the computer is on.

• Your screen saver or power management may be

enabled. Do one of the following to exit from the

screen saver or to resume from Sleep mode:

-Touch the touchpad.

- Press any key on the keyboard.

-Press the power button.

-Press F9 ( ) to confirm whether the backlight for

the LCD screen has been turned off.
