Operation method 

To be checked in prior

  • If the mouse pointer moves on its own, or the app starts on its own, even when you have not touched the touch panel, please perform touch panel calibration, according to the contents in this page.
  • The touch panel on this panel has both touch function and pen function, so it has different specifications than other models. If the cursor moves on its own, you will need to perform the operations on this page. Please keep in mind that there is nothing wrong with the hardware.
  • Please use only genuine AC adapter. Do not use AC adapter from other models or other manufacturer.
  • If you are connecting VAIO power cord to power strip, please connect it either directly to wall outlet or other power outlet.
  • Please keep away anything that generates radio waves, such as florescent light and motor.
  • Please disconnect USB device and cable connected to VAIO.
  • Please wipe off liquid from the touch panel, if any.
  • If dew has occurred due to bringing in the PC from cold environment to warm environment, please use it after it is well-adapted to room temperature.
