All rights reserved.IntroductionThe electronics industry has been proactive in including product features that reduce power le
10、vels whenpossible to save energy and extend battery life. Much of this has been accomplished through industry workwith the U.S. EPA ENERGY STAR programa, and globally, billions of dollars worth of electricity aresaved each year through the use of power management (Kawamoto, et al. B2b). Despite this
11、 success, manydevices that are capable of power management are not saving energy because the power managementfeatures are disabled, incorrectly configured, or thwarted by hardware or software conflicts (PIER 500-03-012f B3), (Roberson, et al. B5), (Webber, et al. B6). For PCs, the great majority are
12、 not power-managing. For monitors, printers, and copiers, the rates are above 50%, but significant improvement is stillpossible. Thus, there is the potential for considerable additional savings through higher enabling rates inpower management. In addition, there are a variety of reasons to expect th
13、at the opportunity for energysavings from power management will only increase in coming years, such as more devices and device typesthat can power manage, greater number of hours these devices are wanted to be available, and greaterdifference between on and sleep states.The goal of this standard is
14、to capture energy savings by increasing the rate at which power managementfeatures are enabled and operate successfully. This standard should lead to other benefits such as improvedease of use and reduced burden of customer support on manufacturers.At present, power management controls in office equ
15、ipment and other electronic devices show littleconsistency in the terms, symbols, and indicators used and in their overall structure. This is particularly trueacross device types (e.g., between a PC and a copier), but often holds even within the same type of device.For example, the standby mode on s
16、ome copiers refers to the state when they are fully on and immediatelyready to act, but the standby mode on some computers and monitors refers to a low-power mode in whichthey have reduced capability and take time to recover. “Standby power“ also is used for a devices minimumpower state, which is an
17、 off state for most devices. The combination of controls and indications of powerstatus is the user interface.The confusion and ambiguity of so many power controls preclude many people from being able tounderstand power controls and power status. The problematic interfaces further deter these people
18、 andothers from attempting to change power management settings or successfully doing so. This standard is intended to accomplish a broad similarity of experience of power controls of any electronicdevice that is used in a normal work or home environment. It is intended to do this through voluntary m
19、eans.It is not intended to stifle innovation in user interfaces, nor preclude deviations from the standard whereclearly warranted.The first draft of this standard was based on research (Nordman, et al. B4) conducted at LawrenceBerkeley National Laboratory, and funded by the Public Interest Energy Re
