66 Mobile Computing Charging the main battery Wall Outlet-The fastest way to charge your tablet is with the included AC adaptor plugged into a wall outlet. To charge the main battery, plug the device into a live electrical outlet. The battery charges whether the device is On or Off. TECHNICAL NOTE: The recharging of the battery may not occur when your device is using all of the power provided by the AC adaptor to run applications, features, and devices. Your device's Power Options utility can be used to select a power level setting that reduces the power required for system operation and will allow the battery to recharge. The battery may not start charging immediately under the following conditions: ❖ The battery is extremely hot or cold. To ensure that the battery charges to its full capacity, wait until it reaches room temperature (50 to 80 degrees Fahrenheit, 10 to 26 degrees Celsius). ❖ The battery is almost completely discharged. Leave the power connected and the battery should begin charging after a few minutes. HINT: Once the battery is fully charged, we recommend that you periodically operate your device on battery power until the battery discharges completely. Please make a complete back up of your data to external media before discharging the battery. For more information, see "Backing up your work" on page 61.
