Happy Work, Happy Life: This records my happy work

A power scheme is a collection of settings that controls the power usage of your computer. You can use power schemes to reduce the power consumption of individual devices or the entire system.

In Windows XP, User can set options for a power scheme in the Power Options dialog box. Windows XP comes with several pre-configured profiles, they are Home/Office Desk, Portable/Laptop, Presentation, Always on, Minimal Power Management and Max Battery. User also can easily create custom profiles that fine tune the properties for his particular circumstances.

In Max OS, Laptops get a menu option in the Energy Saver panel: Optimize Energy Settings. These are energy profiles you can quickly switch between depending on the circumstance: Better Battery Life, Normal, Better Performance and Custom.

In KDE, KPowersave ships with a set of four preconfigured schemes which you can adjust to your needs. To switch schemes with KPowersave just right-click the panel icon and select Set Active Scheme. The following schemes are available:

• Performance Keep your machine running with full power and full speed to achieve maximum performance.

• Acoustic Apply any measure that makes sure your machine runs as quietly as possible.

• Presentation Disable any display power management and screen savers to make sure that your presentation is not interrupted by a blanked display or such like.

• Powersave Apply aggressive power management methods to make sure that your machine runs as long as possible when put on battery power instead of AC power.

How about GNOME Power Manager? Do we need such options which allow user select power profiles which they like?
