WARNING! DO NOT leave the battery pack discharged. The
battery pack will discharge over time. If not using a battery pack,
it must continued to be charged every three months to extend
recovery capacity or else it may fail to charge in the future.
The battery stops charging if the temperature is too high or the
battery voltage is too high.
Charging the Battery Pack
Before you use your Notebook PC on the road, you will have to
charge the battery pack. The battery pack begins to charge as
soon as the Notebook PC is connected to external power using the
power adapter. Fully charge the battery pack before using it for the
first time. A new battery pack must completely charge before the
Notebook PC is disconnected from external power. It takes a few
hours to fully charge the battery when the Notebook PC is turned
OFF and may take twice the time when the Notebook PC is turned
ON. The battery status indicator on the Notebook PC turns OFF when
the battery pack is charged.
The battery starts charging when the charge remaining in
the battery drops below 95%. This prevents the battery from
charging frequently. Minimizing the recharge cycles helps
prolong battery life.
