Touchscreen Troubleshooting
If the touchscreen is not able to access items along the edges of the LCD, it may need to be calibrated. To calibrate the touchscreen,
complete the following steps:
Touchscreen Calibration
Start > Control Panel > Tablet PC Settings > choose Calibrate...You can choose to calibrate Pen input or Touch input.
Perform the point calibrations that appear on the screen to correct the linearity problems.
Touchscreen Sensitivity
The touch screen may start to lose its sensitivity due to foreign particles (such as sticky notes) that are blocking the touch sensors. To
remove these particles:
• Turn off the computer.
• Disconnect the AC adapter cable from the wall outlet.
NOTE: Do not use water or a cleaning liquid to wipe the touch screen.
• Use a clean, lint-free cloth (you may spray mild, non-abrasive cleaner or water on the cloth if needed, but not on the screen) and wipe
the surface and sides of the touch screen to remove any dirt or fingerprints.
