Keyboard problems
Keyboard problems
If, while typing, strange things happen or nothing happens, the 
problem may be related to the keyboard itself.
The keyboard produces unexpected characters.
A keypad overlay may be on. If the numlock light or cursor control 
overlay light is on, press 
Fn + F10
 to turn off the cursor control 
overlay light, or 
Fn + F11
 to turn off the numlock light. 
If the problem occurs when both the keypad overlays are off, make 
sure the software you are using is not remapping the keyboard. 
Refer to the software documentation and check that the program 
does not assign different meanings to any of the keys.
You have connected an external keyboard and the operating 
system displays one or more keyboard error messages.
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.
Display problems
Here are some typical display problems and their solutions:
The screen is blank.
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.
