If your finger reaches an edge of the touch pad, the pointer will not move. You will need to lift your finger, and then place it back on the center of the touch pad.
The pointer may not move temporarily as expected depending on the condition of your VAIO computer.
In such a case, wait for a while before moving the pointer again.
If the pointer still does not move, press the Ctrl+Alt+Delete keys, select(Shut down) in the lower right corner of the computer screen, and then select Shut down.
If the problem persists, press and hold down the(Power) button or slide the(Power) switch to the right for more than four seconds.
Turning off the computer with the Ctrl+Alt+Delete keys, the(Power) button, or the(Power) switch may cause loss of unsaved data.
The touch pad may be disabled. See Why can't I use the touch pad? for more information.
