Multi Media Functions/Equipment 45 Using the Battery Your computer uses a smart rechargeable Lithium-ion (Li-ion) battery pack for power when the AC adapter is not attached to an electrical outlet. The smart battery gives a accurate measurement of the current battery capacity which helps extend operating time by enabling effective power management in operating systems that take advantage of the accurate information supplied by the battery. Charging the Battery Your computer’s battery starts charging automatically when you connect the power to the computer and to an electrical outlet. If the computer is off, the battery charges faster than if the computer’s power is on. Approximate charging times for the Li-Ion battery are: • 1.5 hours with the computer off (Standard battery) and 3 hours (Long Life battery). • 4 hours with the computer on (Standard battery) and 8 hours (Long Life battery). While the battery is charging normally, the battery Status LED on the computer is amber (See “Reading the System Status LEDs” on page 26 for the location of the battery Status LED). When the battery is fully charged, the LED changes to green. When you use a new battery pack for the first time or use a battery after a long period of storage, the initial battery life is shorter than normal. Normal battery life resumes after a few discharge-recharge cycles. Follow these rules for charging your battery: • A battery normally discharges power when not used for long periods of time. Be sure to recharge the battery every two months when it is not in use. • Make it a practice to discharge your battery fully before recharging the battery. This can help extend the life of the battery. • Do not attempt to charge the battery in temperatures of under 50o F(10o C) or over 90o F(32oC.) • If you will not be using the computer for a long period of time (a month or more), you should completely charge the battery. After you have done so, remove the battery from the unit. 46 UsersManual All batteries eventually wear out and lose the ability to hold a charge. You may need to replace your battery pack after a year of average usage. All batteries lose their charge if they sit unused for an extended time period. When not used, battery can discharge fully in 2 to 3 months. Increasing Battery Life If you plan to use your notebook computer without the docking station, increase battery life using the following methods. General Environment Using the methods below you can increase battery life by as much as 1.5 times. • Detach the docking station. • Detach any unnecessary USB and PS/2 devices -(camera, mouse, keyboard etc.) • Do not use any Multimedia programs -(Windows Media Player, audio/video CDs) unless absolutely necessary. Adjust LCD Brightness Reducing the LCD display brightness will reduce the power consumption of the battery. However, if you require the screen to be bright the computer will automatically reduce the brightness after 20 minutes of inactivity. The screen will be returned to original settings when you resume your activities. To reduce the LCD display brightness use the key combination. + Power Management To change the time until your computer goes into reduced power modes, use the system power management function. 1. Click Start > Settings > Control Panel. 2. Double-Click Power Options. The power options panel enables you to reduce the time until your computer goes into standby mode for example. See “Using Power Management Options” on page 57 for instructions on how to use this battery saving tool.

To calibrate the battery complete the following steps: Calibration Notes: You should start the battery calibration process with a fully charged battery, battery status LED is green. The power meter may not show 100%. Before you commence the battery calibration process you should fully charge, then fully discharge and finally fully recharge the battery again. 1. Disconnect the AC power adapter after turning off the system. 2. Restart your computer and press to enter BIOS setup. 3. Using the arrow keys, highl...
