This chapter provides information for operating on battery power, as well as information on how your computer manages and saves power. 33 Battery pack The computer uses a battery pack that gives you long use between charges. English Battery pack characteristics The battery pack has the following characteristics: · · Employs current battery technology standards. Delivers a battery-low warning. The battery is recharged whenever you connect the computer to the mains power supply. Your computer supports charge-in-use, enabling you to recharge the battery while you continue to operate the computer. However, recharging with the computer turned off results in a significantly faster charge time. The battery will come in handy when you travel or during a power failure. It is advisable to have an extra fully charged battery pack available as backup. Contact your dealer for details on ordering a spare battery pack. Maximizing the battery's life Like all other batteries, your computer's battery will degrade over time. This means that the battery's performance will diminish with time and use. To maximize your battery's life, you are advised to adhere to the recommendations set out below. Conditioning a new battery pack Before you use a battery pack for the first time, there is a "conditioning" process that you should follow: 1 2 3 4 5 Insert the new battery without turning the computer on. Connect the AC adapter and fully charge the battery. Disconnect the AC adapter. Turn on the computer and operate using battery power. Fully deplete the battery until the battery-low warning appears. 34 Operating on battery power English 6 Reconnect the AC adapter and fully charge the battery again. Follow these steps again until the battery has been charged and discharged three times. Use this conditioning process for all new batteries, or if a battery hasn't been used for a long time. If the computer is to be stored for more than two weeks, you are advised to remove the battery pack from the unit. Warning: Do not expose battery packs to temperatures below 0°C (32°F) or above 60°C (140°F). Extreme temperatures may adversely affect the battery pack. By following the battery conditioning process you condition your battery to accept the maximum possible charge. Failure to follow this procedure will prevent you from obtaining the maximum battery charge, and will also shorten the effective lifespan of the battery. In addition, the useful lifespan of the battery is adversely affected by the following usage patterns: · Using the computer on constant AC power with the battery inserted. If you want to use constant AC power, you are advised to remove the battery pack after it is fully charged. Not discharging and recharging the battery to its extremes, as described above. Frequent use; the more you use the battery, the faster it will reach the end of its effective life. A standard computer battery has a life span of about 500 charges. · · Installing and removing the battery pack Important! Before removing the battery from the unit, connect the AC adapter if you want to continue using your computer. Otherwise, turn off the computer first. To install a battery pack: 1 Align the battery with the open battery bay; make sure that the end with the contacts will enter first, and that the top surface of the battery is facing up. 35 2 Slide the battery into the battery bay and gently push until the battery locks in place. Slide the battery release latch to release the battery. Pull the battery from the battery bay. English To remove a battery pack: 1 2 Charging the battery To charge the battery, first make sure that it is correctly installed in the battery bay. Plug the AC adapter into the computer, and connect to a mains power outlet. You can continue to operate your computer on AC power while your battery is charging. However, charging the battery with the computer turned off results in a significantly faster charge time. Note: You are advised to charge the battery before retiring for the day. Charging the battery overnight before traveling enables you to start the next day with a fully charged battery. Checking the battery level The Windows Power Meter indicates the current battery level. Rest the cursor over the battery/power icon on the taskbar to see the battery's present charge level. Optimizing battery life Optimizing battery life helps you get the most out of battery operation, prolonging the charge/recharge cycle and improving recharging efficiency. You are advised to follow the suggestions set out below: · · · · Purchase an extra battery pack. Use AC power whenever possible, reserving battery for on-the-go use. Eject a PC Card if it is not being used, as it will continue to draw power. Store the battery pack in a cool, dry place. The recommended temperature is 10°C to 30°C. Higher temperatures cause the 36 Operating on battery power English battery to self-discharge faster. · · Excessive recharging decreases the battery life. Look after your AC adapter and battery. Battery-low warning When using battery power pay attention to the Windows Power Meter. Warning: Connect the AC adapter as soon as possible after the battery-low warning appears. Data will be lost if the battery to become fully depleted and the computer shuts down. When the battery-low warning appears, the recommended course of action depends on your situation: Situation The AC adapter and a power outlet are available. Recommended Action 1.

System activity refers to any activity involving one or more of the following devices: keyboard, touchpad/mouse, hard disk drive, optical drive, peripherals connected to the computer, and video memory. If no activity is detected for a period of time (the settings are controlled in Windows Power Management), the computer turns off some, or all, of these devices in order to conserve power. Your computer employs a power management scheme that supports Advanced Configuration and Power Interface (ACPI), enabling maximum power conservation without compromising system performance. ACPI allows Windows to control the amount of power given to each device attached to the computer. In this way, Windows handles all power-saving chores for your computer. Refer to Windows Help and Support for more information.
