AJ-e.book Page 39 Friday, April 11, 2003 5:18 PM 2 Operating on battery power AJ-e.book Page 40 Friday, April 11, 2003 5:18 PM The computer operates on AC or battery power. This chapter contains the information you need to know to operate the computer on battery power. It also includes information on how your computer manages and saves power. AJ-e.book Page 41 Friday, April 11, 2003 5:18 PM 41 Battery pack The computer uses a battery pack that gives you long use between charges. Battery pack characteristics The battery pack has the following characteristics: • Employs current battery technology standards The computer uses a Lithium-Ion battery pack which does not have the memory effect problem of Nickel Cadmium (NiCd) batteries. Li-Ion batteries consistently provide the longest battery life, best-suited for road warriors. • Battery-low warning When the battery charge level becomes low, the status indicator of the computer flashes at regular intervals. This tells you that the battery power is critically low (and you should save your work). You can correct this situation by recharging the battery pack. Whenever possible, use the AC adapter. 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. The computer supports a secondary battery pack, swappable with the optical drive. See your dealer for more details. Using a battery pack for the first time When using a battery pack for the first time, follow these steps: 1. Connect the AC adapter to a power source and to the computer and fully recharge the battery. 2. Disconnect the adapter to use up the battery before recharging again. You only need to do this once or twice with a new battery or with a battery that's been stored without being used for a long time. If the computer is to be stored for more than two weeks, we suggest you remove the battery pack. Battery power from a fully charged battery pack depletes in roughly a day with the computer in Standby mode, a month in Hibernation mode or when power is off. Warning! Do not expose battery packs to temperatures below 0ºC (32ºF) or above 60ºC (140ºF). This may adversely affect the battery pack. AJ-e.book Page 42 Friday, April 11, 2003 5:18 PM 42 2 Operating on battery power Installing and removing the battery pack Important! Before removing the battery pack, make sure that you have an AC adapter connected to the computer; otherwise, turn off the computer. To install a battery pack: Insert the battery at an angle (1); press gently on the battery (2) until it click into place. Then slide the lock/unlock latch into the lock position (3). AJ-e.book Page 43 Friday, April 11, 2003 5:18 PM 43 To remove the battery pack: Slide the lock/unlock latch into the unlock position (1); slide and hold the battery release latch (2); remove the battery pack by using the built-in slot in the battery pack (3). Charging the battery To charge the battery, install the battery pack and plug the AC adapter into the computer and an electrical outlet. Charging modes The adapter has two charging modes: • Rapid mode The computer uses rapid charging when power is turned off and a powered AC adapter is connected to it. In rapid mode, a fully depleted battery gets 95% charged in approximately 1.5 hours. • Charge-in-use mode AJ-e.book Page 44 Friday, April 11, 2003 5:18 PM 44 2 Operating on battery power When the computer is in use with the AC adapter plugged in, the computer also charges the battery pack if installed. This mode will take longer to fully charge a battery than rapid mode. In charge-in-use mode, a fully depleted battery gets 95% charged in approximately 4 hours. Note: We suggest that you charge the battery pack before retiring for the day, letting it charge overnight before traveling. This ensures a fully charged battery for use the next day. Checking the battery level The Windows battery meter indicates the present battery level. Simply rest your cursor on the battery meter (or AC plug) icon on the taskbar to see the present charge level of your battery. Optimizing battery life This section helps you get the most out of battery operation. Optimizing battery life prolongs the charge/recharge cycle and improves recharge efficiency. Follow these suggestions to optimize and maximize battery power: • Purchase an extra battery pack. • Use the AC adapter whenever possible so that the battery is reserved for onthe-go computing. • Keep the battery pack in the computer powered by the AC adapter. The constant trickle charge maintains the battery level to eliminate the battery self-discharge effect. The charge-in-use function also charges the battery pack. • Eject the PC card from the card slot when it is not in use, since the PC card draws extra power. See “Ejecting a card” on page 56. • Store the battery pack in a cool, dry place. The recommended storage temperature for battery packs ranges from 10 to 30 degrees Celsius. The higher the storage temperature, the faster the battery pack self-discharges. • The batteries can be recharged about 400 times when used as directed. Excessive recharging decreases battery life. • Take care of your battery pack and AC adapter. See “Care and maintenance” on page ix of the preface. AJ-e.book Page 45 Friday, April 11, 2003 5:18 PM 45 Battery-low warning You never have to worry about battery power as long as you are using the AC adapter. However, when you operate the computer on battery power, pay extra attention to the power indicator on the display panel. During a battery-low condition, the power indicator flashes at regular intervals until battery power is depleted. Warning! Connect the AC adapter to the computer as soon as possible. Data is lost when computer power is cut off during Standby mode. The following table shows the recommended course of action to take when you encounter a battery-low condition. Situation Recommended Action AC adapter and power outlet available 1. Connect the AC adapter to the computer. 2. Save all necessary files. 3. Resume work. Power off the computer if you wish to recharge the battery rapidly. An extra fully-charged battery pack available 1. Save all necessary files. 2. Exit the application. 3. Power off the computer. 4. Replace the battery pack. 5. Power on the computer and resume work. AC adapter or power outlet not available 1. Save all necessary files. 2. Exit the application. 3. Power off the computer. Power management This computer has a built-in power management unit that monitors system activity. System activity refers to any activity involving one or more of the following devices: keyboard, mouse, floppy drive, hard disk, peripherals connected to the serial and parallel ports, and video memory. If no activity is detected for a period of time (called an inactivity timeout), the computer stops some or all of these devices in order to conserve energy. This computer employs a power management scheme that supports ACPI (Advanced Configuration and Power Interface) which allows for maximum power
