This chapter provides information for operating on battery power, as well as information on how your computer manages and saves power. As1300_E.book Page 29 Tuesday, July 9, 2002 2:01 PM 29 Battery pack Your computer uses a re-chargeable Ni-Mh or Li-Ion battery pack. Battery pack characteristics The battery pack has the following characteristics: • Employs current battery technology standards. • Delivers a battery-low warning. To prolong the life of your Ni-Mh battery pack, fully deplete the battery before recharging. A Li-Ion battery, however, can be recharged at any time. 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 Insert the new battery in the computer. Do not turn the computer on. 2 Connect the AC adapter and fully charge the battery. 3 Disconnect the AC adapter. 4 Turn on the computer and operate using battery power. 5 Fully deplete the battery until the battery-low warning appears. 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. English As1300_E.book Page 30 Tuesday, July 9, 2002 2:01 PM English 30 Operating on battery power 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 lifespan 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. 2 Slide the battery into the battery bay and gently push until the battery locks in place. To remove a battery pack: 1 Slide the battery release latch to release the battery. 2 Pull the battery from the battery bay. As1300_E.book Page 31 Tuesday, July 9, 2002 2:01 PM 31 Charging th...
