6Quick Reference Guide 13 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 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, access the Control Panel→ 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. You can install an optional second battery in the media bay to significantly increase operating time. Operating time is significantly reduced when you perform operations including, but not limited to, the following:

• 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 3D games

• Running the computer in maximum performance mode (see "Configuring Power Management Settings" on page 17) 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 before you insert the battery into the computer (see "Checking the Battery Charge" on page 14). You can also set power management options to alert you when the battery charge is low (see "Configuring Power Management Settings" on page 17). 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 lithium ion 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.14 Quick Reference Guide 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 <Fn><F3> to display the QuickSet Battery Meter. The Battery Meter displays status, battery health, charge level, and charge completion time for the battery in your computer. For more information about QuickSet, click the QuickSet icon in the Microsoft

taskbar, and click Help. Microsoft

Power Meter The Windows Power Meter indicates the remaining battery charge. To check the Power Meter, double- click the icon on the taskbar. 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 the battery has 80 percent of its charge remaining, four of the lights are on. If no lights appear, the battery has no charge.Quick Reference Guide 15 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 and by using the Battery Meter in Dell QuickSet. For information about QuickSet, right-click the QuickSet icon in the Microsoft

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" in your online User’s Guide 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. 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 in QuickSet or the Power Options Properties window. See "Configuring Power Management Settings" on page 17 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.

• Place the computer in standby mode or hibernate mode when you leave the computer unattended for long periods of time (see "Power Management Modes" on page 15).

• Use the Power Management Wizard to select options to optimize your computer’s power usage. These options can also be set to change when you press the power button, close the display, or press <Fn><Esc>. NOTE: See "Power Management Modes" on page 15 for more information on conserving battery power. Power Management Modes Standby Mode Standby mode conserves power by turning off the display and the hard drive after a predetermined period of inactivity (a time-out). When the computer exits standby mode, it returns to the same operating state it was in before entering standby mode. NOTICE: If your computer loses AC and battery power while in standby mode, it may lose data.16 Quick Reference Guide To enter standby mode:

• Depending on how you set the power management options in the Power Options Properties window or the QuickSet Power Management Wizard, use one of the following methods: – Press the power button. – Close the display. – Press <Fn><Esc>. To exit standby mode, press the power button or open the display depending on how you set the power management options. You cannot make the computer exit standby mode by pressing a key or touching the touch pad or track stick. Hibernate Mode Hibernate mode conserves power by copying system data to a reserved area on the hard drive and then completely turning off the computer. When the computer exits hibernate mode, it returns to the same operating state it was in before entering hibernate mode. NOTICE: You cannot remove devices or undock your computer while your computer is in hibernate mode. Your computer enters hibernate mode if the battery charge level becomes critically low. To manually enter hibernate mode:

• Depending on how you set the power management options in the Power Options Properties window or the QuickSet Power Management Wizard, use one of the following methods to enter hibernate mode: – Press the power button. – Close the display. – Press <Fn><Esc>. NOTE: Some PC Cards or ExpressCards may not operate correctly after the computer exits hibernate mode. Remove and reinsert the card (see "Installing a PC Card or Express Card" in your online User’s Guide), or simply restart (reboot) your computer. To exit hibernate mode, press the power button. The computer may take a short time to exit hibernate mode. You cannot make the computer exit hibernate mode by pressing a key or touching the touch pad or track stick. For more information on hibernate mode, see the documentation that came with your operating system.Quick Reference Guide 17 Configuring Power Management Settings You can use the QuickSet Power Management Wizard or Windows Power Options Properties to configure the power management settings on your computer.

Performance and Maintenance

Power Options . For information on any field in the Power Options Properties window, click the question mark icon on the title bar and then click on the area where you need information. Charging the Battery NOTE: With Dell™ ExpressCharge™, when the computer is turned off, the AC adapter charges a completely discharged battery to 80 percent in about 1 hour and to 100 percent in approximately 2 hours. Charge time is longer with the computer turned on. You can leave the battery in the computer for as long as you like. The battery’s internal circuitry prevents the battery from overcharging. When you connect the computer to an electrical outlet or install a battery while the computer is connected to an electrical outlet, the computer checks the battery charge and temperature. If necessary, the AC adapter then charges the battery and maintains the battery charge. If the battery is hot from being used in your computer or being in a hot environment, the battery may not charge when you connect the computer to an electrical outlet. The battery is too hot to start charging if the light flashes alternately green and orange. Disconnect the computer from the electrical outlet and allow the computer and the battery to cool to room temperature. Then connect the computer to an electrical outlet to continue charging the battery. For more information about resolving problems with a battery, see "Power Problems" in your online User’s Guide. Replacing the Battery CAUTION: Before performing these procedures, turn off the computer, disconnect the AC adapter from the electrical outlet and the computer, disconnect the modem from the wall connector and computer, and remove any other external cables from the computer. 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. NOTICE: You must remove all external cables from the computer to avoid possible connector damage. For information about replacing the second battery, which is located in the media bay, see "Using Multimedia" in your online User’s Guide.18 Quick Reference Guide To remove the battery:
