•
The battery pack is a consumable product
and the following conditions will shorten
its life:
– when frequently charging the battery
– when using, charging, or storing the
battery in high temperature condition
•
To avoid hastening the deterioration of
the battery pack thereby prolonging its
useful life, minimize the number of times
you charge it so as not to frequently
increase its internal temperature.
•
Charge the battery pack between 10 °C ~
30 °C (50 °F ~ 86 °F) temperature range.
A higher environment temperature will
cause the battery pack's temperature to
rise. Avoid charging the battery pack inside
a closed vehicle and in hot weather con-
dition. Also, charging will not start if the
battery pack is not within the allowed
temperature range.
•
It is recommended that you do not charge
the battery pack more than once a day.
•
It is recommended that you charge the bat-
tery pack with the computer's power off.
•
To maintain the battery pack's operating
efficiency when removed from the com-
puter, store it in a cool dark place and with
30% ~ 40% charge remaining.

Important guidelines
When installing or removing the battery
pack take note of the following:
– avoid installing or removing the battery
pack when the computer is in Sleep mode.
Abruptly removing the battery
pack may
cause loss of data or the computer may
become unstable.
– avoid touching the battery pack termi-
nals or damage may occur, causing im-
proper operation to it or the computer.
The computer's input voltage and sur-
rounding temperature will directly affect
the charge and discharge time:
– charging time will be prolonged when
the computer is turned on. To shorten
the charging time, it is recommended
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).
•
Do not leave the battery pack in storage
for more than six months without
recharging it.
Touchscreen Guidelines (Select
Models Only)
•
Use the finger or the included stylus on the
display. Using a sharp or metallic object
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 with the power
on may cause improper operation.
•
Do not use excessive force on the display.
Avoid placing objects on top of the display
as this may cause the glass to break thereby
damaging the display.
•
In low and high temperatures (below 5
41 °F and above 60
C / 140 °F), the touch-
o
screen may have a slower response time or
register the touch in the wrong location.
It will go back to normal after returning
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.
