HP TouchSmart PCs - Troubleshooting Touch Screen Issues in Windows 7

This support document pertains to HP TouchSmart PCs with Windows 7.

Pressing the touch screen does not do anything

Pressing the touch screen in Windows 7 or the TouchSmart software does not do anything. The mouse pointer does not move or objects are not highlighted.

Perform each of the following steps until the mouse pointer moves to a point that is touched on the Windows desktop:

  1. Clean the screen.

    With the computer off, spray glass cleaner onto a soft, damp cloth and gently wipe the screen to remove dirt and smudges. Do not spray cleaner directly onto the screen. Give special attention to the upper left and right inside edges of the screen. Turn the computer on when finished.

    Press the screen to see if it responds. If not, continue.

  2. Turn off the computer from the Start menu, and unplug the power cord.

  3. With the power cord unplugged, press the power button on the computer case and wait 5 seconds.

  4. Plug in the power cord, and press the power button to turn on the computer.

    Press the screen to see if it responds. If not, continue.

  5. Make sure that the touch options are enabled as follows:

    1. Click Start , and then Control Panel.

    2. Click Hardware and Sound.

    3. Scroll down and click Pen and Touch.

    Press the screen to see if it responds. If not, continue.

  7. If the touch screen still does not work, use Performing an HP System Recovery (Windows7) to restore the system to its original system configuration.

    Press the screen to see if it responds. If not, continue.

  8. Use Testing for Hardware Problems Using Hardware Diagnostic Tools (Windows 7) .

A touch occurs next to the point touched, not at the point of touch

If you suspect that touch functionality is not working correctly in Windows 7, 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 1.3 centimeters (.5 inch) away from the tip of your finger, you should clean and calibrate the screen. 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. Do not spray cleaner directly onto the screen and give special attention to the upper left and right corners of the screen. To calibrate the screen, see Calibrating the Screen (Windows 7) .
