RUNNINGTHE NOTEBOOK
ON ITS BATTERY
Recharging the battery
1. Connect theACadapterto yournotebook.
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.
Before using the supplied battery pack
for the very first time after purchase,
remember to charge it fully.If a charged
batteryhas notbeenrechargedformore
thana month, chargeitfully beforeusing
it.
When the battery is fully charged while
the notebook is in power off mode, the
Battery Level LED indicator turns off.
When the battery is 90% or more
charged, it cannot be recharged even if
the AC adapter is connected. The
batterycanberecharged whenitspower
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
degradeswhenit isusedin anextremely
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
batteryfrom 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.)
