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.

• 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.

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 system

partition (C drive) to the original factory contents

using OneKey Recovery. If you still see only the

cursor on the screen, have the computer serviced.
