Display Periodically inspect the display to make sure the contrast and brightness functions are operating properly
and that all pixels are operational.
To clean your touch screen
To clean the display assembly, use the same cleaning solution and procedure described earlier for the outside case. In
some cases, you can use a small amount of isopropyl alcohol to remove streaks or smears. Use a soft, clean cloth to
clean the display. Do not use paper products because they can scratch the screen.
External Power Connector The external power connector may sometimes be exposed to moisture and/or contami-
nation causing an unreliable connection to the external power source.
Clean the connector using a cotton swab dipped in isopropyl alcohol.
RJ-11 Connector Make sure this connector is operating properly. During normal use, the connector pins can get
dirty or become broken, bent, or pushed out of place. Clean the connector with a cotton swab dipped in isopropyl
alcohol.
If the connector needs to be replaced, this can be done without returning the unit for service. Contact your local
support person for more information.
Keyboard Check all keys to make sure they are working properly. To clean the keyboard, use the same cleaning
solution and procedure described above for the outside case.
If keyboard problems persist, the keyboard might need to be replaced. This can be done without returning the unit for
service. Contact your local support person for more information.
I/O Ports Make sure the video, serial, and parallel ports are operating properly. Periodically inspect the ports for
damage or contamination, and make sure the cover is attached to the computer. The I/O cover can be replaced
without returning the unit for service. Contact your local support person for more information.
PC Card Door and Connector Whenever possible, make sure this door is closed and latched properly. When the
PC Card door is closed, it provides a watertight seal for the PC Card socket. Shield the area from all contaminants
such as liquids, rain, snow, and dust when the door is open.
