Get all the performance you can out of your laptop computer. Don't let Windows, or applications conserve a small amount of electricity just so they can feel green, or put a certification on your device. Set Windows power scheme to high performance to allow your PC to run as fast as it wants, however this is not a setting for moble laptop use. Changing this setting will not increase the speed or performance of your desktop PC, but can with a laptop depending on current settings.
Windows and manufactures are under pressure from various government agencies, consumer groups, and certifiers to reduce the overall electrical consumption of their devices. In order to meet certain criteria, or receive a certification manufactures include a means to reduce the electrical consumption of their devices. One way this is achieved is with the Windows power plan. Windows power plans vary in execution, some are custom configured by the device manufacture, or certification groups like Energy Star, which then would then certify the device as Energy Star compliant. In general Windows power plans are great for laptops, and devices to help keep them cool, and running longer on batteries.
Changing this setting will not make your personal computer any faster, and your computer will seem like nothing has changed, and that is normal. High performance just tells Windows, and applications not to reduce power usage. You many notice the fan running a bit louder, and that is normal it is because Windows is allowing your desktop PC to work a little harder at keeping itself cool. Over the years manufactures have improved these settings as hardware has improved, yet they are still questionable in their application. Not all power plans work well, and some reduce the devices performance down to a snails pace.
If you are trying to conserve power, or are using a portable device then leave the power scheme set to balanced or the manufactures default setting. When running on batteries every ampere hour counts. However, If you meter your device at the wall and use both settings, the difference is negligible. When a laptop is used as a desktop, or it will always be plugged in then PCMD recommends using the high performance power plan. Laptops tend to be slower than the average desktop, and squeezing every bit of performance out of one can improve the overall experience.
