Your computer is equipped with two types of cursor-pointing devices: the pointing stick and the touch pad.
✍
You can disable/enable the pointing devices. To change the pointing device settings, use the VAIO Control Center.
!
Be sure to connect a mouse before disabling both pointing devices (the pointing stick and the touch pad). If you disable both devices before connecting
a mouse, you will be able to use only the keyboard for pointer operations.
Simultaneous use of the two pointing devices is not possible. If you attempt to use the pointing stick and the touch pad simultaneously, the pointing
device you touched later may not work for several seconds. In this case, take your fingers off the pointing devices and wait for several seconds.
