Solving Problems
If the touch screen starts losing its
sensitivity
— The touch screen may have
foreign particles (such as sticky notes) that are
blocking the touch sensors. To remove these
particles:
Turn off the computer. 1.
Disconnect the power cord from the wall outlet.
2.
CAUTION: Do not spray water or a cleaning
liquid directly on the touch screen.
Use a clean, lint-free cloth (can spray mild, 3.
non abrasive cleaner or 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.
Beep Codes
Your computer might emit a series of beeps during
start-up if there are errors or problems. This
series of beeps, called a beep code, identifies a
problem. Write down the beep code and contact
Dell (see “Contacting Dell” on page 63).
