Lenovo Tablet YOGA 11S 用户手册

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.

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 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 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.

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.
