Keyboard problems
If, when you type, 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
mode light is on, press
Fn + F10 to turn off the cursor control mode
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.
The keyboard you connected may be defective or incompatible with
the computer. Try using a different make of keyboard.
Nothing happens when you press the keys on the external
keyboard.
You may have plugged the external keyboard in while the computer
was turned on. Using the computer’s TouchPad, click Start, then
either Shut Down or Turn off computer, and then Restart the
Computer. The computer will restart and recognize the device.
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.
