Using a Battery37 Using a Battery Battery Performance NOTE: For information about the Dell warranty for your computer, see the Product Information 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 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, access the Control Panel, click Power Options, and then click the Power Meter tab. 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. 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, media memory cards, or USB devices Using high-brightness display settings, 3D screen savers, or other power-intensive programs such as 3D games Running the computer in maximum performance mode (See Configuring Power Management Settings on page 41.) NOTE: It is recommended that you connect your computer to an electrical outlet when writing to a CD or DVD. You can check the battery charge (see Checking the Battery Charge on page 38) before you insert the battery into the computer. You can also set power management options to alert you when the battery charge is low. See Configuring Power Management Settings on page 41 for information about accessing QuickSet or the Power Options Properties window. 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 a battery from other computers with your computer.
38Using a Battery 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 Charge The Dell QuickSet Battery Meter, the Microsoft® Windows® Power Meter window and icon, the battery charge gauge and health gauge, and the low-battery warning provide information on the battery charge. Dell™ QuickSet Battery Meter If Dell QuickSet is installed, press to display the QuickSet Battery Meter. The Battery Meter displays status, charge level, and charge completion time for the battery in your computer. For 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 icon on the taskbar. For instructions on accessing more information about the Power Meter, see Configuring Power Management Settings on page 41. If the computer is connected to an electrical outlet, a icon appears. Charge Gauge By either pressing once or pressing and holding the status button on the charge gauge on the battery, 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. That is, a battery can show a status of charged but maintain a reduced charge capacity (health). Check the Battery Charge To check the battery charge, press and release 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 four of the lights are on, the battery has 80 percent of its charge remaining. If no lights appear, the battery has no charge.
Using a Battery39 Check the Battery Health NOTE: You can check battery health in one of two ways: by using the charge gauge on the battery as described below or by using the Battery Meter in Dell QuickSet. For information about QuickSet, right-click the icon in the taskbar, and 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. 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 on page 157 for more information about the battery operating time. Low-Battery Warning NOTICE: To avoid losing or corrupting data, save your work immediately after a low-battery warning, and then connect the computer to an electrical outlet. If the battery runs completely out of power, hibernate mode begins automatically. By default, a pop-up window warns you when the battery charge is approximately 90 percent depleted. You can change the settings for the battery alarms. See Configuring Power Management Settings on page 41 for information about accessing QuickSet or the Power Options Properties window. Conserving Battery Power Perform the following actions to conserve battery power: Connect the computer to an electrical outlet when possible because battery life is largely determined by the number of times the battery is used and recharged.
