Keyboard Problems

If you are having trouble with the keyboard, check the
following:
1. If the screen displays one of the following keyboard errors
when you turn on or reset the computer, make sure the
keyboard is securely connected to the computer:

See 'Connecting the Keyboard" in Chapter 1 for
instructions.
2. If the cursor keys do not work properly, the Num Lock
function may be on. When Num Lock is on, the numeric/
arrow keys on the numeric keypad work only as numbers.

corner of the keyboard is lit; if it is, press the

function when you turn on the computer, see "Using the
Speaker and Keyboard Options" in Chapter 2.
