Your computer system uses both a lithium-ion battery pack and a nickel-metal hydride (NiMH) coin cell battery. For instructions about replacing the
lithium-ion battery pack in your computer, see "Replacing the Battery." The NiMH battery is a long-life battery, and it is very possible that you will
never need to replace it. However, if this battery ever needs to be replaced, the procedure must be performed by an authorized service technician.
Do not dispose of these batteries along with household waste. Contact your local waste disposal agency for the address of the nearest battery
deposit site.
About Battery Power
You automatically conserve battery power each time you connect the computer to an electrical outlet. The battery is even being recharged when
you use AC power. The battery's life expectancy is largely determined by the number of charges it receives, so use an electrical outlet to run the
computer whenever possible.
You can customize power management by individually controlling the computer's power management features. These features reduce power
consumption by monitoring application programs and computer devices for inactivity and slowing down or stopping some of the computer’s
internal devices.
Experiment with power conservation features to achieve the optimum power conservation for your work environment.
Turning On the Computer
To turn on the computer, press the power button.

NOTES: When you use power conservation features, you often trade some of the performance of the computer for increased battery
operating time. For example, if you turn off the hard-disk drive, you may experience a delay the next time the computer tries to access
the hard-disk drive.
Other power conservation features, such as suspend (or standby) mode, stop almost all system activity. They allow you to maximize
power conservation when your work is interrupted.
NOTES: If your computer's operating system is "locked up"—that is, it does not respond to commands—press and hold down the power
button for at least five seconds to turn off the computer.
If the operating system locks up and does not respond to the power button, you can restart the computer using the reset switch on the
bottom of the computer. To do so, straighten a paper clip and press it into the reset switch access hole for about one second.
