Note
Be sure the keyboard plug is inserted into the keyboard
socket and not the mouse socket.
See “Connecting the Keyboard” in Chapter 1 for
instruct ions.

function may be on. When num lock is on, the numeric/

comer of the keyboard is lit; if it is, press the
Num Lock
key
to turn off the function.

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

“The Computer Does Not Respond,” above to see if
something other than the keyboard is causing the problem.

If there is no display on the screen, check that the monitor’s
power switch is on and that the power light on the monitor
is lit. If the power light is on but you still do not see
anything on the screen, check the monitor’s brightness and
contrast controls.
If the power switch is on but the power light is not, turn off
the monitor’s power, wait five seconds, and turn the power
back on. Wait to see if the screen displays any text.
