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 2.5 hours (Long Life battery).
• 4 hours with the computer on (Standard battery) and 5 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 27 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 10oC or over 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.
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.
