Using a Battery: Dell Latitude ATG D620 User's Guidefollowing:● Using optical drives ● Using wireless communications devices, PC Cards, ExpressCards, media 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) 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) 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). 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. 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 MeterIf Dell QuickSet is installed, press <Fn><F3> to display the QuickSet Battery Meter.

That is, a battery can show a status of "charged" but maintain a reduced charge capacity (health). file:///H|/My%20Documents/Cellular/User%20Guides/Notebooks/D620%20ATG/battery.htm (3 of 9)4/13/2007 4:36:30 PM
Using a Battery: Dell Latitude ATG D620 User's GuideCheck 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 the battery has 80 percent of its charge remaining, four of the lights are on. If no lights appear, the battery has no charge.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 Battery 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. Then connect the computer to an electrical outlet, or install a second battery in the media bay. If the battery runs completely out of power, hibernate mode begins automatically. The battery status light on the hinge cover (at the lower-right corner of the display) flashes orange when the battery charge is low, and it is solid orange when the battery charge is critically low. Also, a pop-up window warns you when the battery charge is approximately 90 percent depleted. If two batteries are installed, the low-battery warning means that the combined charge of both batteries is approximately 90 percent depleted. The computer enters hibernate mode when the battery charge is at a critically low level.You can change the settings for the battery alarms in QuickSet or the Power Options Properties window. See Configuring Power Management Settings 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 file:///H|/My%20Documents/Cellular/User%20Guides/Notebooks/D620%20ATG/battery.htm (4 of 9)4/13/2007 4:36:30 PM
