If the battery pack will not be used for a long period of
time (a month or more), charge or discharge (use) the
battery pack until the remaining battery level becomes
30% to 40% and store it in a cool, dry place.
This computer prevents overcharging of the battery by
recharging only when the remaining power is less than
approx. 95% of capacity.
The battery pack is not charged when the computer is
first purchased. Be sure to charge it before using it for
the first time. When the AC adaptor is connected to the
computer, charging begins automatically.
Should the battery leak and the fluid get into your
eyes, do not rub your eyes. Immediately flush your
eyes with clear water and see a doctor for medical
treatment as soon as possible.
NOTE
The battery pack may become warm during recharging
or normal use. This is completely normal.
Recharging will not commence if internal temperature
of the battery pack is outside of the allowable tempera-
Ref-
ture range (0 °C to 50 °C {32°F to 122°F}) (
erence Manual “Battery Power”). Once the allowable
range requirement is satisfied, charging begins auto-
matically. Note that the recharging time varies based
on the usage conditions. (Recharging takes longer
than usual when the temperature is 10 °C {50°F} or
below.)
If the temperature is low, the operating time is short-
ened. Only use the computer within the allowable tem-
perature range.
This computer has a high temperature mode function
that prevents the degradation of the battery in high
temperature environments. (
“Battery Power”) A level corresponding to a 100%
charge for high temperature mode is approximately
equivalent to an 80% charge level for normal tempera-
ture mode.
Reference Manual
The battery pack is a consumable item. If the amount
of time the computer can be run by using a particular
battery pack becomes dramatically shorter and
repeated recharging does not restore its performance,
the battery pack should be replaced with a new one.
When transporting a spare battery inside a package,
briefcase, etc., it is recommended that it be placed in a
plastic bag so that its contacts are protected.
Always power off the computer when it is not in use.
Leaving the computer on when the AC adaptor is not
connected will exhaust the remaining battery capacity.
