NOTE: You can use your media base to charge a computer battery. However, a battery in a media base does not power the media base or the computer. In addition, when your computer is connected to a media base (docked), the Battery Meter window includes a Dock Battery tab, which displays the charge level and current status of the media base battery. The following icons appear in the Battery Meter window: l The computer or media base is running on battery power. l The battery is discharging or idle. l The computer or media base is connected to an electrical outlet and running on AC power. l The battery is charging. l The computer or media base is connected to an electrical outlet and running on AC power. l The battery is idle. For more information about QuickSet, right-click the icon in the taskbar, and click Help. Microsoft Windows Power Meter The Windows Power Meter indicates the remaining battery charge. To check the Power Meter, double-click the about the Power Meter tab, see "Power Management." icon on the taskbar. For more information If the computer is connected to an electrical outlet, a Charge Gauge icon appears. Before you insert a battery, press the status button on the battery charge gauge to illuminate the charge-level lights. Each light represents approximately 20 percent of the total battery charge. For example, if the battery has 80 percent of its charge remaining, four of the five lights are on. If no lights appear, the battery has no charge. Health Gauge The battery operating time is largely determined by the number of times it is charged. After hundreds of charge and discharge cycles, batteries lose some charge capacity, or battery health. To check the battery health, press and hold the status button on the battery charge gauge for at least 3 seconds. If no lights appear, the battery is in good condition, and more than 80 percent of its original charge capacity remains. Each light represents incremental degradation. If five lights appear, less than 60 percent of the charge capacity remains, and you should consider replacing the battery. See "Specifications" for more information about the battery operating time.
