Power save
mode uses a battery efficiently to conserve a computer's energy.
Laptops have introduced convenience and mobility into the world of computing, but these ultra-modern devices are easily put out of action by a dying battery. Power save mode was designed to offer computer users the option of enabling low-power settings that conserve energy and extend battery life.
Description
Power save mode consists of a group of settings that can be used to reduce the amount of energy consumed by a computer's display and hard drive. These power options are especially useful when a laptop is unplugged, and they're included with the major operating systems, Windows OS and Mac OS.
Display Settings
In power save mode, the computer can automatically dim the backlight in the screen or shut off the display entirely after a specified time, reducing the energy required to power the machine.
Hard Drive Settings
Depending on the operating system version, a computer can be programmed to automatically shut down or to enter hibernate, sleep or standby mode. In hibernation, sleep or standby modes, the computer remains on but switches to a low-power setting. These conservation modes are set to go into effect when the computer is idle or when you close a laptop.
Considerations
Energy Star, a program of the Environmental Protection Agency, estimates that activating the recommended power management settings could result in as much as $352 in energy savings for the average computer user over a four-year period.
