Power 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 been unused 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, later in this chapter. Displaying Charge Information on the Screen This section explains how to access and interpret battery charge displays. Viewing Charge Displays To view information about the status of any battery pack in the notebook: » Select the Power Meter icon in the notification area (at the far right of the taskbar). - or - » Select Start > Control Panel > Performance and Maintenance > Power Options > Power Meter tab. 2-24 Hardware and Software Guide
