The computer's input voltage and sur-
rounding temperature will directly affect
the battery pack's charge and discharge
time:
– charging time will be prolonged when
the computer is turned on.
To shorten the charging time, it is recom-
mended that you place the computer in
Sleep or hibernation mode.
– a low temperature will prolong the
charging time as well as hasten the dis-
charge time.
When using battery power in an extremely
low temperature environment, you may
experience shortened operating time and
incorrect battery level reading. This phe-
nomenon comes from the chemical char-
acteristics of batteries. The appropriate
operating temperature for the battery is
-10 C ~ 50 C (14 F ~ 122 F).
Touchscreen Guidelines
Use the finger or the included stylus on the
display. Using a sharp or metallic object
other than your finger or stylus may cause
scratches and damage the display, thereby
causing errors.
Use a soft cloth to remove dirt on the dis-
play. The touchscreen surface has a special
protective coating that prevents dirt from
sticking to it. Not using a soft cloth may
cause damage to the special protective
coating on the touchscreen surface.
Turn off the computer power when clean-
ing the display. Cleaning the display with
the power on may cause improper opera-
tion.
Do not use excessive force on the display.
Avoid moving the computer while holding
the display or twisting the display. Avoid
placing objects on top of the display as
this may cause the glass to break thereby
damaging the display.
Using the touchscreen during low tempe-
o
rature (less than 5
C) may cause a slower
response time. This is normal. A normal
response time may be restored upon re-
turning to room temperature.
When there is a noticeable discrepancy in
the placement of the stylus on the screen
and the indicated position of the onscreen
pointer, use the calibration utility to reca-
librate the touchscreen display.
