CHECK THE MOUSE CABLE —
Shut down the computer. Disconnect the mouse
cable, check it for damage, and 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 —
1
Shut down the computer.
2
Disconnect the mouse.
3
Turn on the computer.
4
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.)
TEST THE MOUSE CONTROLLER —
To test the mouse controller (which affects
pointer movement) and the operation of the touch pad or mouse buttons, run
the Mouse test in the
Pointing Devices
test group in the Dell Diagnostics (see
"Dell Diagnostics" on page 101).
REINSTALL THE TOUCH PAD DRIVER —
See "Reinstalling Drivers and Utilities" on
page 140.
