Touch Pad or Mouse Problems
CHECK THE TOUCH PAD SETTINGS —
1 Click Start → Control Panel → Hardware and Sound → Mouse .
2 Adjust the settings, as needed.
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 —
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" on page 99.
REINSTALL THE TOUCH PAD DRIVER — See "Reinstalling Drivers and Utilities"
on page 127.
