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.
