ON ITS BATTERY
Recharging the battery
Connect the AC adapter to your notebook
The moment you connect an AC adapter
to your notebook, the notebook begins to
charge the internal standard battery pack.
When the battery level indicator turns off
after the battery is completely charged,
(while the notebook is in off mode)
disconnect the AC adapter from the
notebook.
1.
2.
Before using the supplied battery
pack for the very first time after
purchase, remember to charge it fully.
If a charged battery has not been
recharged for more than a month,
charge it fully before using it.
When the battery is fully charged while
the notebook is in power off mode, the
Battery Charging Indicator turns off.
When the battery is 90% or more
charged, it cannot be recharged even if
the AC adapter is connected. The battery
can be recharged when its power level(i.e.
remaining battery life) is 89% or less. This
is a mechanism to protect and extend the
battery life.
When a notebook is turned off, the Battery
Level LED indicator goes off immediately
if the battery is completely charged.
The chargeability of the battery degrades
when it is used in an extremely hot or cold
place.
When the battery is very hot, for
example, immediately after long usage
of the notebook, the battery protection
feature may be activated to prevent the
battery from being recharged. When the
temperature decreases, the notebook
automatically begins to charge the battery.
When an optional modular bay battery
is installed, it is charged along with
the internal standard battery. (Optional
modular bay battery is applicable to
selected models only.)
