charge is below 90%, the battery begins charging and the Charging icon appears in the Status display. If the battery charge is 90% or higher when you connect DC power, the battery will not charge, preventing battery overcharging.
2.Look at the Battery Gauge icon in the Status display to determine the percent of charge in the battery. See “Status Display” in Chapter 1 of this manual for a description of the Battery Gauge icon.
As long as DC power remains connected to the Tablet PC, the charging process continues until the battery charge reaches 100%. Approximate charge times shown in Table

Table 2-2. Battery Charging Time
Also note the following with respect to charging the battery:
•You can use the system, suspend system operation, or shut down and turn off the system without interrupting the charging process; however, using the system while the battery is charging will cause the battery to charge at a slower rate, as noted in Table 2- 2, “Battery Charging Time".
•As noted in the procedure above, the system will not begin charging the battery if the battery charge level is 90% or higher when the system is initially connected to external DC power. (This prevents the battery from being overcharged.)
•The battery uses Lithium ion battery cells which have no “memory effect.” You do not need to discharge the battery before you begin charging.
•If a charged battery is not available, save your work and close all running programs, then shut down the system or Hibernate
•Plug in an external DC power source.
2.Slide the battery release latch in the direction indicated. (See Figure
3.Pull the battery away from the system, as shown in the illustration and remove the battery from the Tablet PC.
If you are using an external battery charger, refer to the instructions provided with the battery charger.
Under Federal, state, or local law, it may be illegal to dispose of batteries by putting them in the trash. Be sure to dispose of batteries in accordance with local government regulations.
To install the battery:
1.Orient the battery with the slides in the empty battery tray. Slide the battery into the tray and press it firmly until it is seated. When it is properly seated, the battery release latch should return to position and lock the battery.
Figure 2-4. Removing the Battery
Once the battery is installed, you can resume system operation or start and use your system normally.
REMOVING AND INSTALLING THE BATTERY
The battery can be removed from the Tablet PC and swapped with a charged battery. The battery can then be charged in an external charger if one is available. To remove the battery from the Tablet PC:
1.Choose one of the following:
•If a charged battery is available, you can suspend system operation. A
TIPS FOR CONSERVING BATTERY POWER
You can extend the charge life of your battery by conserving battery power. (Your results may vary depending on your application and how the system is configured.) Here are some suggestions to help you conserve battery power:
•Use an external power source such as the AC adapter whenever the system is docked.
•Suspend system operation if you know that you won’t be using the system for a while.
•Shut down the system if you won’t be using the system for an extended period of time.
