1.7 UMPC Accessories
AC Adapter
The AC Adapter supplies external power to your UMPC and charges the
internal battery pack simultaneously. The AC adapter has an auto-switching
design that can connect to any 100VAC ~ 240VAC power outlets. Change the
power cord if you are going to use your UMPC in countries with different
connector outlets.
When you connect the AC adapter, it charges the battery whether or not the
UMPC is powered on.
Battery Pack
Aside from the AC adapter, your UMPC 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 UMPC
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.
