Keyboard problems

After a period of time, the battery will lose its ability to perform at
maximum capacity and will need to be replaced. This is normal for
all batteries.
For more information on maintaining battery power, see “Changing
the main battery” on page 78.
Keyboard problems

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.
If you are using the built-in screen, make sure the display priority is
not set for an external monitor. To do this, press F4. If this does not
correct the problem, press F4 again to return the display priority to
its previous setting.
HINT: Pressing the F4 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 F4 to make sure the display priority is not set for the built-
in screen.
