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 set correctly, 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 Lenovo

OneKey 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 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 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.
