Input

The Tablet PC does not respond to the pen I am using

You may be using an improper input device. Only Motion tablet pens can be used to write on the Tablet PC display. The Tablet PC does not respond to other pens or to a plastic stylus.

You may be using the wrong tablet pen. Occasionally, a particular tablet pen may not work with a particular Tablet PC. If you are in an environment with multiple tablets and pens, try using a different pen. You can also tether the pen to the tablet to ensure that a pen stays with its tablet.

The pointer on the screen does not align with the tablet pen

The pen may need to be calibrated. See “Calibrate the digitizer” on page 7.

When I write, I inadvertently click the function button on the pen

Try adjusting how you hold the pen. Avoid resting your finger on the function button. You can also disable the button. See “Configuring pen options” on page 27.
