Precautions (Battery Pack)
• 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.
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 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.
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
direct sunlight, in a hot place (in an automobile
on a sunny day, for example), or in a cold place.
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.
Do Not Put into a Microwave
Do not put the battery pack into a microwave
oven or a pressurized chamber.
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 touch the terminals on the battery pack. The bat
tery 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
become 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 Iluid 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.
* •
• 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})C?’
"Battery Power". Once the allowable range re
quirement is satisfied, charging begins automatically.
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 less.)
• If the temperature is low', the operating time is shortened. Only
use the computei' within the allowable temperature mnge.
• 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 com
puter has been used with the display at the brightest .set
ting 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).
• The battery pack is a consumable item. If the amount of
time the computer can be run off a particuhir battery pack
becomes dramatically shorter and repeated rechargings do
not restore its performance, the battery pack should be
replaced with a new one.
• When a spare battery pack is to be carried in a pocket or
bag, 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 adapter is not
connected will exhaust the remaining battery capacity.
