The cursor keys on the numeric keypad do not work
properly.
If the Num Lock light in the upper right corner of the keyboard
is lit, press
NumLock
to turn off the function.
If you want to change the initial settings of the num lock
function, see “Setting Keyboard 0ptions” in Chapter 1.
Mouse Problems
Your mouse isn’t working properly or you see an auxiliary
device error message.
Make sure the mouse cable is securely connected to the
M O U S E
port and not the K/Bport. Also make sure you installed the
mouse driver correctly (if necessary). See the documentation
that came with your mouse and Chapter 1 for instructions. (The
Windows installation program automatically installs a mouse
driver for Windows applications.)
Monitor Problems
There is no display on the screen.
Check that the monitor’s power switch is on and that its power
light is lit.
The power light is on, but you still do not see anything on
the screen.
Check the brightness and contrast controls.
If you still do not see anything on the screen, make sure the
monitor is securely connected to the computer.
