Precautions ( Battery Pack )
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 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 temperature
range (0 °C to 50 °C {32°F to 122 °F})
Power". Once the allowable range requirement is satis-
fied, charging begins automatically. Note that the recharg-
ing time varies based on the usage conditions. (Recharg-
ing takes longer than usual when the temperature is 10 °C
{50 °F} or below.)
If the temperature is low, the operating time is shortened. Only
use the computer within the allowable temperature range.
This computer has a high temperature mode function that
prevents the degradation of the battery in high tempera-
ture environments. (
corresponding to a 100% charge for high temperature mode
is approximately equivalent to an 80% charge level for
normal temperature mode.
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
rechargings do 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.
