Charging a New Battery Pack, Monitoring the Charge of a Battery Pack, Calibrating a Battery

Page 52 highlights

Power Charging a New Battery Pack Fully charge the battery pack while the tablet PC is connected to external power through the AC adapter. A new battery pack that has been partially but not fully charged can run the tablet PC, but the battery light may be inaccurate. The primary battery pack charges when it is inserted into the tablet PC and the tablet PC is connected to external power. Charging an In-Use Battery Pack To prolong battery life and increase the accuracy of battery light: ■ Allow a battery pack to discharge to 10 percent of a full charge through normal use before charging it. ■ When you charge a battery pack, charge it fully. Monitoring the Charge of a Battery Pack This section explains several ways you can determine the amount of charge in your battery pack. Obtaining Accurate Charge Information To increase the accuracy of all battery charge displays: ■ Allow a battery pack to discharge to about 10 percent of a full charge through normal use before charging it. ■ When you charge a battery pack, charge it fully. ■ If a battery pack has not been used for one month or more, calibrate the battery pack instead of simply charging it. For calibration instructions, refer to the "Calibrating a Battery Pack" section in this chapter. Hardware and Software Guide 2-22

Charging a New Battery Pack
Fully charge the battery pack while the tablet PC is connected to
external power through the AC adapter.
A new battery pack that has been partially but not fully charged
can run the tablet PC, but the battery light may be inaccurate.
The primary battery pack charges when it is inserted into the
tablet PC and the tablet PC is connected to external power.
Charging an In-Use Battery Pack
To prolong battery life and increase the accuracy of battery light:
Allow a battery pack to discharge to 10 percent of a full
charge through normal use before charging it.
When you charge a battery pack, charge it fully.
Monitoring the Charge of a Battery Pack
This section explains several ways you can determine the amount
of charge in your battery pack.
Obtaining Accurate Charge Information
To increase the accuracy of all battery charge displays:
Allow a battery pack to discharge to about 10 percent of a full
charge through normal use before charging it.
When you charge a battery pack, charge it fully.
If a battery pack has not been used for one month or more,
calibrate the battery pack instead of simply charging it. For
calibration instructions, refer to the
“Calibrating a Battery
Pack”
section in this chapter.
