If, while typing, strange things happen or nothing happens, the 
problem may be related to the keyboard itself.

You may need to update your keyboard driver. Refer to the 
documentation that came with the keyboard or to the keyboard 
manufacturer's Web site.

The keyboard you connected may be defective or incompatible with 
the computer. Try using a different make of keyboard.

Here are some typical display problems and their solutions:

Display Auto Off may have gone into effect. Press any key to 
activate the screen.

You may have activated the instant password feature by pressing 

Fn

and

F1 

simultaneously. If you have registered a password, press 

any key, type the password and press 

Enter

. If no password is 

registered, press any key. The screen reactivates and allows you to 
continue working.

If you are using the built-in screen, make sure the display priority is 
not set for an external monitor. To do this, press 

Fn

and

F5

 

simultaneously (once). If this does not correct the problem, press 

Fn

and

F5 

simultaneously again to return the display priority to its 

previous setting.

HINT: Holding the 

Fn

 key and pressing the 

F5

 key several times will 

advance you through the display options.

If you are using an external monitor:

❖

Check that the monitor is turned on.

❖

Check that the monitor’s power cord/cable is firmly plugged 
into a working power outlet.

❖

Check that the cable connecting the external monitor to the 
computer is firmly attached.

❖

Try adjusting the contrast and brightness controls on the 
external monitor.

❖

Press 

Fn

 and 

F5

 simultaneously to make sure the display 

priority is not set for the built-in screen.
