AC Adapter 
The AC Adapter supplies external power to your notebook computer and 
charges the internal battery pack simultaneously. The AC adapter has an auto-
switching design that can connect to any 100VAC ~ 240VAC power outlets. 
You just change the power cord if you are going to use your notebook in other 
countries with different connector 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.
