1. Open the MobilePro display panel. 
2. Locate the stylus holder on the lower right of the dis-
play panel. To remove the stylus, slide it away from the

!CAUTION 
Although you can use your fingertip to activate the 
touch screen, never use hard-pointed or sharp ob-
jects. These objects can damage the touch screen. 
3. Gently touch the pointed tip of the stylus to the screen 
to select an object. When you are done using the stylus, 
return it to its convenient holder on the MobilePro. 
USING MOBILEPRO’S POWER SOURCES 
The NEC MobilePro 780 can be powered using the AC 
adapter or the system’s main battery, making it a truly 
portable system. The MobilePro also contains a built-in, 
backup battery that recharges whenever the unit is con-
nected to an AC power source. Read the following sec-
tions for information about using the NEC MobilePro’s 
power sources. 
Determining Battery Status 
You can determine battery status by using the power icon 
on the lower right-hand side of the taskbar or through the 
power icon in the control panel. 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).  
						

							  
Introducing the NEC MobilePro  2-11 
To display battery status, use one of the following meth-
ods. 
!Double tap the battery/plug icon on the taskbar, if pre-
sent. 
!Go to Start, Settings, Control Panel, and double tap the 
power icon. 
Recharging the Main Battery Pack 
The main battery pack contains rechargeable Lithium-Ion 
cells. Recharge a battery pack when you see the following 
message displayed on your screen. 
Main Batteries Very Low 
To recharge a battery pack installed in the battery bay, 
connect the AC adapter. See “Connecting the AC Adapter” 
in Chapter 1. 
The battery charging LED indicates the charging status of 
the main battery pack when the NEC MobilePro is con-
nected to an AC power source. The LED status displays as 
follows: 
!Lights amber while charging. 
!Lights green when fully charged. 
It takes approximately 4.5 hours to recharge a fully de-
pleted battery pack regardless of the system’s power state. 
However, if the main battery has been depleted for a pro-
longed period, you must also allow time for the backup 
battery to fully recharge (see the section, Recharging the 
Backup Battery).  
						

							  
2-12 Introducing the NEC MobilePro  
 Note: Through normal use, the capacity of a 
battery pack gradually declines. Should you notice 
that the battery does not stay charged as long as ex-
pected, it is probably necessary to replace the bat-
tery with a new one. Please refer to the section 
Battery Replacement in this chapter. Depending 
upon use, a battery pack should recharge from full 
depletion approximately 300 times during the life of 
the battery. 
Recharging the Backup Battery 
The backup battery charges while the main battery is 
charging. It usually takes approximately 4.5 hours to re-
charge both the main and backup batteries together. 
A full 10 hours charging time is required under either of 
these circumstances: 
!this is the first time you have used your MobilePro 
!the main battery has been in a depleted state for a pro-
longed period. 
In these cases, allow ten hours for both the main and 
backup batteries to charge, even if the LED indicator on 
the front of the MobilePro lights green before the full 10 
hours are passed. 
To protect your data, do not use the system until the 
backup battery is charged. 
To recharge the main and backup batteries, connect the 
AC adapter. See the section, “Connecting the AC Adapter” 
in Chapter 1.  
						

							  
Introducing the NEC MobilePro  2-13 
MobilePro Power Management 
When your MobilePro is connected to an AC power source 
and the main battery is removed from the system, be sure 
to replace the main battery before disconnecting the AC 
adapter to prevent possible data loss. 
!CAUTION 
The MobilePro’s internal data backup battery pro-
vides power to maintain the memory contents for a 
limited period of time when the main battery is re-
moved and the unit is not connected to an AC power 
source. The backup battery does not provide suffi-
cient power to operate the system. 
Do not remove the main battery from the unit for an 
extended period of time unless the unit is connected 
to an AC power source. The backup battery is not 
user replaceable. 
Battery Replacement 
Note the following when replacing batteries: 
!If the main battery becomes weak, the MobilePro auto-
matically turns off. Recharge or replace the main 
battery immediately if the power goes off. 
!MobilePro has a built-in backup battery that maintains 
your data for several hours whenever the main battery 
is depleted or removed. The backup battery is re-
charged whenever the unit is connected to an AC power 
source. 
!If you fail to replace a depleted main battery for an ex-
tended period of time and the back-up battery is weak, 
the contents of the MobilePro memory and all user data 
may be lost.

Removing and Inserting the Battery Pack 
Should you notice the life of a charged battery pack is 
short, replace it with a new one. Follow these instructions 
to replace a battery pack. 
1. Save your data, turn off unit power, and close the dis-
play panel. Disconnect any cables attached to the unit, 
such as the AC adapter cable. 
 Note: If you receive messages indicating that 
both the main battery and the backup battery are 
very low, immediately connect the AC adapter to 
charge both batteries. 
2. Have a new Lithium-Ion battery pack available.
