If you do not find your problem here, see Chapter 1. The following section only describes problems

that might negate the need to refer to the more comprehensive information in Chapter 1.

Display problems

When I turn on the computer,

nothing appears on the screen.

• If the screen is blank, make sure that:

- The AC power 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 its original factory

contents using the recovery system. If you still see only the

cursor on the screen, have the computer serviced.

The screen goes blank while

the computer is on.

• Your power management is enabled. Do one of the following

to resume from sleep or hibernation mode:

- Press any key on the keyboard. (Notebook mode only)

- Press the Power button.

- Press the Windows button.

- Press F9 ( ) to confirm whether the backlight of the

LCD screen has been turned off.

Sleep or hibernation problems

The critical low-battery error

message appears, and the

computer immediately turns off.

• The battery power is getting low. Connect the AC power

adapter to the computer.

The computer enters sleep

mode immediately after

Power-on.

• Make sure that:

- The battery is charged.

- The operating temperature is within the acceptable range.

See “Chapter 2. Use and care Information” in the Lenovo

Safety and General Information Guide.

Note: If the battery is charged and the temperature is within range, have the computer serviced.
