Battery Pack
Aside from the AC adapter, your computer can also be powered through
the internal battery pack. The battery pack uses rechargeable Lithium-Ion
(Li-Ion) battery cells that provide long computing hours when fully
charged and power management enabled. You should always leave the
battery inside your computer even when using the AC adapter as it also
acts as a back-up power supply in case power from the AC adapter is cut
off. It is also very important to have the battery pack always charged to
prevent battery cell degradation.
