Solving Problems
If the touch screen starts losing its
sensitivity —
• Calibrate the touch screen (see “Touch
Screen Calibration” on page 44).
• The touch screen may have foreign particles
(such as sticky notes) that are blocking the
touch sensors. To remove these particles:
a. Turn off the computer.
b. Disconnect the power cable from the wall
outlet.
c. Use a clean, lint-free cloth (can spray
water on a cloth if needed, but not on the
screen) and wipe the surface and sides
of the touch screen to remove any dirt or
fingerprints.
