Precautions
NOTE
The battery pack may become warm during recharging or
normal use. This is completely normal.
Recharging will not commence outside of the allowable
temperature range (0 °C to 45 °C (32°F to 113 °F))
"Battery Power". Once the allowable range re-
quirement is satisfied, charging begins automatically. Note
that the recharging time varies based on the usage condi-
tions. (Recharging takes longer than usual when the tem-
perature is 10 °C (50 °F) or less.)
If the temperature is low, the operating time is shortened. Only
use the computer within the allowable temperature range.
Although the battery has remaining capacity, the battery
indicator may light up red or emit a beep. This indicates a
significant rise in the temperature (60 °C (140 °F) or more)
of the battery pack
"Battery Power". This is
typically caused by the fact that the battery pack has been
delivering a high level of power because the computer has
been used with the display at the brightest setting and with
the power-saving function off.
To protect the battery pack from increases in temperature,
the brightness of the display automatically decreases, al-
lowing the temperature of the battery to drop. In this con-
dition, if the computer is left as is, it will automatically go
off after about three minutes have elapsed. Within that
period, therefore, be sure to connect the AC adapter or
shut the computer OFF after saving any open data (if nec-
essary).
Care should be exercised with regard to the following in
order to avoid the possibility of liquid leakage, overheat-
ing, or bursting.
Avoid Heat
Do not throw the battery pack into a fire or
expose it to excessive heat.
Do Not Disassemble
Do not insert sharp objects into the battery pack,
expose it to bumps or shocks, deform, disas-
semble, or modify it.
Do Not Short
Do not short the positive (+) and negative (-)
contacts.
Do Not Put into a Microwave
Do not put the battery pack into a microwave
oven or a pressurized chamber.
Avoid Extreme Heat, Cold and Direct Sun-
light
Do not charge, use or leave the battery pack for
extended periods where it will be exposed to di-
rect sunlight, in a hot place (in an automobile on
a sunny day, for example), or in a cold place.
Keep Articles Away
Do not place the battery pack together with ar-
ticles such as necklaces or hairpins when carry-
ing or storing.
Do not touch the terminals on the battery pack. The battery
pack may no longer function properly if the contacts are dirty
or damaged.
Do not expose the battery pack to water, or allow it to be-
come wet.
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 re-
charging 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 adapter 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.
Discontinue Use
Should the battery emit an abnormal odor, be-
come hot to the touch, become discolored,
change shape, or become in any way different
from normal, remove it from the computer or
charger and discontinue use.
Do Not Use With Any Other Computer
The battery pack is rechargeable and was in-
tended for the specified computer or charger. Do
not use it with a computer other than the one for
which it was designed.
CAUTION
The charging terminal of the
battery pack is used with the
battery charger, which is sold
separately.
Never connect anything to the charging terminal other than
the exclusive adapter that is supplied with the battery charger.
Doing so could damage the device connected to the battery
pack, the cable, and the battery pack itself. It could also
result in overheating or bursting.
Charging Terminal
Incorrectly using peripheral devices may lead to a decrease
in performance, an increase in temperature and/or damage
your computer. For more information on peripheral devices,
please refer to the Reference Manual.
