The AC adapter has an autoswitching design that can connect to any 100VAC ~ 240VAC power outlets.

When you connect the AC adapter, it charges the battery whether or not the notebook computer is powered on. 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. 28
