A Word About Power

Depending on the support your laptop manufacture provides, you might have some or a lot of control over how much power your laptop consumes over time. Power consumption is an important issue for laptop users due to the limited storage of laptop batteries.

When you open your Control Panel and select Power Options, you'll see a window similar to the Power Options Properties window in Figure 17.6. From this window, you can select the power scheme that best suits the way you work. If you change the option to Always On, your laptop battery will be utilized to its fullest because Windows XP will always keep your monitor on and your hard disks spinning. By selecting other options, you can control how long your keyboard sits idle because Windows XP stops your hard disk and blanks out your monitor to save battery life. When you press any key, after one of these power-saving features starts, you will notice a pause while Windows XP brings the disk back to its full speed or powers the monitor once again.
