How to Save Laptop Battery Power When You Really Need it(2)

3.Choosing a Power Scheme

Windows XP offers two Power Schemes appropriate for laptops on the go. These are

Portable/Laptop and Max Battery. They can both be chosen in the Power Schemes tab of the

Power Options Properties box. Both power schemes conserve battery power. But Portable

laptop adjusts what it conserves to the amount of power you need at the time, while Max

Battery is much less flexible. It keeps your computer at a very low constant power rate no

matter what you may be doing. So if you are planning on watching a DVD on that flight, which

uses a lot of battery power, I don’t recommend using the Max Battery power scheme. It might

not give you enough power.

Each power scheme also has its own settings for when the monitor and hard disks should be

turned off. Remember that both are huge energy hogs, and that both the monitor and hard disk

remain on longer under Portable/Laptop than they do under Max Battery.

The power scheme you choose also determines how long the computer will wait to go into

Standby mode or Hibernate after remaining idle. Standby conserves energy because it turns off

your hard disk and monitor. However, whatever you were working on at the time stays in

memory (RAM) instead of being saved safely to your hard drive. The upside of Standby, though,

is that when you press any key your computer will come out of the mode rather quickly.

Hibernation saves even more energy because it saves your work to the hard drive and then

shuts your computer down almost all the way. Inherently, of course, this means it takes the

computer longer to wake up to its normal state, but when everything does come back on, it looks

the same as before. To switch your computer to Standby mode manually, click on Start, then on

Turn off Computer, then on Standby. To make your computer Hibernate manually, click on Start

and Turn off Computer again, but this time hold down the Shift key down afterward. The

Standby key switches to “Hibernate.?Click it and your computer will go into Hibernation mode.
