Using the Battery   37

Your computer uses a rechargeable lithium-ion battery pack for 
power when the AC adapter is not attached to an electrical 
outlet. 

Your computer’s battery starts charging automatically when 
you connect the AC adapter to the computer. If the computer is 
off, the battery charges faster than if the computer’s power is on.

Approximate charging times for your battery are

•

3 hours with the computer off

•

5 hours with the computer on

While the battery is charging, the battery charge light on the 
computer is amber (see Figure 9 on page 21 for the location of the 
battery charge light). When the battery is fully charged, the light 
changes to green.

You can also use the optional external battery cradle to charge 
the battery while it is not in the computer. (See “Battery Cradle” 
on page 92 for more information.)

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 

41
