If your laptop or Chromebook has a touch screen, it's enabled and turned on by default. If for some reason your touch screen is not working, you can try turning it on manually. You can also try calibrating the touch screen if it's not working correctly.

Choose an action from the list below and follow the steps to enable, calibrate, or disable the touch screen on your laptop or Chromebook. Not all Windows laptops or Chromebooks feature a touch screen display.

Check your laptop or Chromebook specifications to determine if it features a touch screen display. There are no Apple MacBooks or desktops that support touch screen. The only exception is the touch bar found on they keyboard of some MacBook Pro models.

Flicks are a specialized kind of gesture that only works with stylus or touch input. All you have to do to use them is perform an action-you flick. Flicking your pen to the left generates a left or back action.

Flicking your pen to the right generates a right or forward action. Better yet, flicks work the same whether you generate them with the pen or with your finger. I love using flicks for reading long Web pages that extend beyond the bottom of the browser window. You can configure flicks too Figure 3. You can use the basic four pre-assigned navigational flicks, or you can assign your own custom actions to any of the eight combined navigational and editing flicks up, up-right, right, down-right, down, down-left, left, up-left.

I mentioned earlier, when introducing the touch pointer, that it was designed to help bridge the gap between the coarse targeting of a fingertip and the busy space most users call their desktop. As desktop resolutions get higher and higher, and desktop screens get bigger and bigger, the visual elements drawn on those screens get closer and closer together.

How do you expect an average user to double-click with their finger on a single control that contains 20 items? With the introduction of touch input, developers must take a small step back and think about how they guide users to interact with their applications. A few small changes may be all you need to make your apps touch-friendlier. Just plan for the ergonomic realities of touch input. For example, if a pen is detected, you could lay down medium-point ballpoint ink.

If you find the input is touch-generated, you could query the area of the contact, set the cursor size to be the area of the contact, and apply a smudge effect, or finger paint. The possibilities are yours to discover. If a sound is heard when the touch screen is pressed, the touch screen hardware is functional and the problem is probably related to calibration and software.

Touch anywhere on the screen and the mouse pointer moves to the upper left of the screen. Gently touch the eraser to the mouse pointer and hold it until a beep is heard - about one second.

If the touch screen still does not work, use HP System Recovery to restore the system to its original system configuration. A touch occurs next to the point touched, not at the point of touch If you suspect that touch functionality is not working correctly, go to the Windows desktop and press the wallpaper background.

If the mouse pointer moves directly under the tip of your finger, touch functionality is working correctly. If the mouse pointer moves more than 1. To do so, with the computer off, spray glass cleaner onto a soft, damp cloth and gently wipe the screen to remove dirt and smudges.
