2.1Using the Battery Pack
The notebook is designed to operate with one of the following power sources:
•With AC power using the AC adapter connected to an electrical outlet.
•With a Lithium-Ion (Li-Ion) battery pack.
You should use the AC adapter whenever it is possible, relying on the battery pack only when AC power is unavailable.
Before you use your notebook computer, install and recharge the battery pack first. The rechargeable Li-Ion battery pack allows you to operate the notebook without an external power source. When you connect the AC power adapter, the battery immediately starts to recharge. For maximum battery performance, fully discharge the battery before recharging it the first time. To do so, unplug the AC adapter, turn off power management features (through Setup and Windows), and turn on the system. Once the battery is fully discharged, plug in the AC adapter and recharge the battery.
If you do not discharge the battery completely, it may fail to accept a full recharge.
+Li-Ion battery is vulnerable, do not charge it with other power adapter, or it may cause fire or explosion.
