RUNNING THE NOTEBOOK

ON ITS BATTERY

Recharging the battery

1. 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.
2. 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.
P OI NT
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 Level LED indicator turns off.
P OI NT
Do not power off the notebook when the
disk drive access indicator is shown.
Failure to do so corrupt data on the disk
as well as the installed operating system.

P OINT
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.
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.)
