English 33 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. • Delivers a battery-low warning. The battery is recharged whenever you connect the computer to the AC adapter. 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. 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. 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 without turning 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.
