Troubleshooting the mouse and touchpad
My mouse does not work.
❑ If you are using an external mouse, check that the mouse is plugged into the
mouse port. See “Connecting an External Mouse or Keyboard” for more
information.
❑ If you are using an optional Sony USB mouse PCGA-UMS1 series, check
that the mouse is plugged into the USB port.
❑ If you are still experiencing problems, use your supplied Application
Recovery CD(s) to reinstall the mouse drivers. See “Using Your Recovery
CDs” for more information.
My touchpad does not work properly.
❑ You may have disabled the touchpad without a mouse being connected to the
notebook. To enable the touchpad:
1 Press the Windows key and use the arrow keys to select Programs, and
then Sony Notebook Setup.
2 Select the Touchpad tab using the arrow keys.
3 Select Enable Touchpad, and then press Enter.
❑ You must restart the notebook to make the touchpad work again.
❑ If your touchpad is interpreting a single tap as a double-click, you must
adjust the button assignments. Follow these steps:
1 Press the Windows key and use the arrow keys to select Control Panel,
and then Mouse.
2 Change the button assignments in the Mouse Properties dialog box.
(One of the buttons is assigned to the double-click action.)
