Running the computer on battery power

The computer contains a removable lithium ion (Li-ion) battery pack that provides power to the computer when it is not connected to an AC outlet. You can recharge the battery many times.

In addition to the removable lithium ion battery, the computer has an internal real-time clock (RTC) battery. This is a nickel metal hydride (NiMH) battery. The RTC battery powers the RTC memory, which stores your system configuration settings and the current time and date for up to a month while the computer is turned off.

TECHNICAL NOTE: For optimum DVD performance, always play DVDs while your computer is connected to AC power.

Maximizing battery life

A battery can be recharged many times. Gradually over time it will lose its ability to hold a charge. To maximize the life of your battery:

❖Avoid leaving the computer plugged in and unused for more than a few hours. Overcharging the battery may shorten its life.

❖If you are not going to use the computer for a long period of time, remove the battery.

❖Alternate between battery packs if you have a spare.

❖Make sure your computer is turned off, or in Hibernation mode, when you are replacing the battery.

❖Store spare battery packs in a cool dry place out of direct sunlight.
