Using MobilePro's Power Sources
The NEC MobilePro 800 can be powered using the AC
adapter or the system's main battery, making it a truly
portable system. The MobilePro also contains an internal data
backup battery that recharges whenever the unit is connected
to an AC power source. Read the following sections for
information about using the NEC MobilePro's power sources.
Determining Battery Status
You can determine battery status by using the battery icon on
the left side of the display panel or through the power icon on
the lower right side of the taskbar. The icon on the taskbar
displays as an electrical plug when the battery is fully
charged (battery charging LED lights green) or as a battery
while charging (battery charging LED lights amber).
To display battery status, use one of the following methods:

Tap the battery icon on the left side of the MobilePro
display panel.

Tap the battery/plug icon on the taskbar, if present.
Recharging the Main Battery Pack
The main battery pack contains rechargeable Lithium-Ion
cells. Recharge a battery pack when the system displays a
low battery warning.
To recharge a battery pack installed in the battery bay,
connect the AC adapter. See "Connecting the AC Adapter" in
Chapter 1.
It takes approximately 4.5 hours to recharge a fully depleted
battery pack regardless of the system's power state.
