cable is securely inserted into the headphone connector (see "Right Side
View" on page 27).

CHECK THE MOUSE CABLE — Shut down the computer, disconnect the mouse
cable and check it for damage, then firmly reconnect the cable.
If you are using a mouse extension cable, disconnect it and connect the
mouse directly to the computer.
TO VERIFY THAT THE PROBLEM IS WITH THE MOUSE, CHECK THE TOUCH PAD —

Shut down the computer.

Turn on the computer.

At the Windows
desktop, use the touch pad to move the cursor around,
select an icon, and open it.
If the touch pad operates correctly, the mouse may be defective.
CHECK THE SYSTEM SETUP PROGRAM SETTINGS — Verify that the system setup
program lists the correct device for the pointing device option (the computer
automatically recognizes a USB mouse without making any setting
adjustments).
