Introduction to Your MobilePro Power System 3
Backup Battery
The MobilePro is equipped with a built-in backup battery to protect
against data loss, should the main battery become discharged or be
removed. The backup battery is recharged whenever the unit is connected
to its AC adapter. Once your unit is powered off due to low battery, the
backup battery, together with the charge remaining in the main battery,
can maintain your data for up to a week.
The backup battery is not a user serviceable part.
For details about installing the battery and connecting the unit to an AC
power source, refer to Chapter 1, “Getting Started,” in the NEC
MobilePro User’s Guide.
Determining Battery Status
You can determine battery status using the power icon in the Control
Panel. For additional details, refer to the section, “Determining Battery
Status,” in Chapter 2 of the user’s guide.
Recharging the System Batteries
Recharging the MobilePro’s main and backup batteries couldn’t be easier!
Simply connect the unit to an AC power source. Recharging time for the
system batteries is approximately 5 hours with the system on or off.
