If you do not find your problem here, see Chapter 2. The following section only describes problems that might negate the need to refer to the more comprehensive information in Chapter 2.

Display problems

When I turn on the computer, nothing appears on the screen.

When I turn on the computer, only a white cursor appears on a blank screen.

My screen goes blank while the computer is on.

•If the screen is blank, make sure that:

-The battery is installed correctly.

-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.)

-The memory is installed correctly.

•If these items are properly set, and the screen remains blank, have the computer serviced.

•Restore backed-up files to your Windows environment or the entire contents of your hard disk to the original factory contents using OneKey Recovery. If you still see only the cursor on the screen, have the computer serviced.

•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 or hibernation mode:

-Touch the touchpad.

-Press any key on the keyboard.

-Press the power button.

-Press Fn+F2 to confirm whether the LCD screen has been turned off.
