Using a Battery 47Using a BatteryBattery PerformanceNOTE: For information about the Dell warranty for your computer, see the ProductInformation Guide or separate paper warranty document that shipped with your computer.For optimal computer performance and to help preserve BIOS settings, operate your Dell™ portable computer with the main battery installed at all times. One battery is supplied as standard equipment in the battery bay.NOTE: Because the battery may not be fully charged, use the AC adapter to connect your new computer to an electrical outlet the first time you use the computer. For best results, operate the computer with the AC adapter until the battery is fully charged. To view battery charge status, place the mouse cursor over the battery icon in the Windows notification area.NOTE: Battery operating time (the time the battery can hold a charge) decreases over time. Depending on how often the battery is used and the conditions under which it is used, you may need to purchase a new battery during the life of your computer.NOTE: It is recommended that you connect your computer to an electrical outlet when writing to media.Battery operating time varies depending on operating conditions. Operating time is significantly reduced when you perform operations including, but not limited to, the following:• Using optical drives.• Using wireless communications devices, ExpressCards, memory cards, or USB devices.• Using high-brightness display settings, 3D screen savers, or other power-intensive programs such as complex 3D graphics applications.• Running the computer in maximum performance mode (see "Configuring Power Management Settings" on page 50 for information about accessing Windows Power Options Properties or Dell QuickSet, which you can use to configure power management settings).
48 Using a BatteryYou can check the battery charge before you insert the battery into the computer. You can also set power management options to alert you when the battery charge is low.CAUTION: Using an incompatible battery may increase the risk of fire or explosion. Replace the battery only with a compatible battery purchased from Dell. The battery is designed to work with your Dell computer. Do not use batteries from other computers with your computer. CAUTION: Do not dispose of batteries with household waste. When your battery no longer holds a charge, call your local waste disposal or environmental agency for advice on disposing of a lithium-ion battery (see "Battery Disposal" in the Product Information Guide).CAUTION: Misuse of the battery may increase the risk of fire or chemical burn. Do not puncture, incinerate, disassemble, or expose the battery to temperatures above 65°C (149°F). Keep the battery away from children. Handle damaged or leaking batteries with extreme care. Damaged batteries may leak and cause personal injury or equipment damage. Checking the Battery ChargeYou can check the battery charge on your computer using any one of the following methods:• Dell QuickSet Battery Meter• Microsoft Windows battery meter icon located in the notification area• Battery charge/health gauge located on the battery• Low-battery warning pop-up windowDell QuickSet Battery MeterTo view the Dell QuickSet Battery Meter:• Double-click the Dell QuickSet icon in the taskbar, and then click BatteryMeteror• Press <Fn><F3>The Battery Meter displays the status, battery health, charge level, and charge completion time for the battery in your computer.
Using a Battery 49For more information about QuickSet, right-click the QuickSet icon, and then click Help.Microsoft® Windows® Battery MeterThe battery meter indicates the remaining battery charge. To check the battery meter, double-click the icon in the notification area. Charge GaugeBy either pressing once or pressing and holding the status button on the battery charge gauge, you can check:• Battery charge (check by pressing and releasing the status button)• Battery health (check by pressing and holding the status button)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. Therefore, a battery can show a status of charged, but maintain a reduced charge capacity (health).Check the Battery ChargeTo check the battery charge, press and release the status button on the battery charge gauge to illuminate the charge indicator 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 lights are on. If no lights are on, the battery has no charge.Check the Battery HealthNOTE: You can check battery health in one of two ways: by using the charge gauge on the battery, as described below, and by using the Battery Meter in Dell QuickSet. For information about QuickSet, right-click the QuickSet icon in the notification area, and then click Help.To check the battery health using the charge gauge, press and hold the status button on the battery charge gauge for at least 3 seconds to illuminate the health indicator lights. Each light represents incremental degradation. If no lights appear, the battery is in good condition, and more than 80 percent of its original charge capacity remains. If five lights appear, less than 60 percent of
50 Using a Batterythe charge capacity remains, and you should consider replacing the battery (see "Battery" on page 185 for more information about the battery operating time).Low-Battery WarningNOTICE: To avoid losing or corrupting data, save your work immediately after a low-battery warning, then connect the computer to an electrical outlet. If the battery runs completely out of power, Sleep state begins automatically.A pop-up window warns you when the battery charge is approximately 90 percent depleted. The computer enters Sleep state when the battery charge is at a critically low level.You can change the settings for the battery alarms in Dell QuickSet or the Power Options window (see "Configuring Power Management Settings" on page 50).Conserving Battery PowerTo conserve battery power on your portable computer, do any of the following:• Connect the computer to an electrical outlet when possible; battery life is largely determined by the number of times the battery is used and recharged.• Configure the power management settings using either Dell QuickSet or Microsoft Windows Power Options to optimize your computer’s power usage (see "Configuring Power Management Settings" on page 50). • Use the Sleep power state when you leave the computer unattended for long periods of time (see "Using the Sleep Power State" on page 51).Configuring Power Management SettingsYou can use Dell QuickSet or Windows Power Options to configure the power management settings on your computer.• For information on how to use the Dell QuickSet Power Management wizard, right-click the QuickSet icon in the notification area, click Help,and then select Power Management.
