Improved and Standard User Interface for Power Management Bruce Nordman Lawrence Berkeley National Laboratory BNordman@LBL.gov http://eetd.LBL.gov/Controls May, 2000 sponsor: California Energy Commission

Overview: 

Overview Energy Implications Facts and Assumptions Non-Office Eqt. Controls Office Equipment Controls Project Elements

Office Equipment Energy UseAnnual Electricity (TWh/year): 

Office Equipment Energy Use Annual Electricity (TWh/year) No Power Management Now (ENERGY STAR) Potential (100% Enabling)

Energy Savings: 

Energy Savings TWh/year $billion/year Existing 27.1 2.2 Potential 16.7 1.3 Current Power Mgmt. Enabling Rates: PCs: 25% Monitors: 60% Printers: 80% Copiers: 70%

Facts: 

Facts PC power management enabling rates are low; other devices could be higher PM Controls and Indicators are inconsistent and often confusing or ambiguous Potential PC PM savings are increasing

Assumptions: 

Assumptions More understanding of existence and operation of power management will lead to it being used better and more often. Improved and Standard User Interface elements will improve understanding. Existence of Standard and advocates for it will lead to adoption of it for new products.

Our Project: 

Our Project Goal: Save extra energy by getting more use out of already existing power management capability in office equipment. Means: Over a few years achieve a broad similarity of user experience of power management across all office equipment. Do this via a voluntary standard.

Office Equipment:The “Standby” Problem: 

Suspend mode is known as standby mode under the Microsoft Windows 98 operating system. For systems with ACPI compliance, suspend mode is known as sleep mode” (Dell) stand-by mode” — Fully ready to copy but not copying. (ASTM Copier Test Procedure) “Stand-By — … an optional operating state of minimal power reduction …” (VESA Standard) “Standby power — The lowest power mode in which the appliance is plugged in …” (LBNL-Leaking/Standby Electricity) “Standby is … the lowest power state where the system is responsive to interrupts …” (PowerPC Reference Platform) "Suspend is currently ignored under Windows 95/98 and Windows 2000 because the terminology is ill-defined. “ (Microsoft) There is no distinction between Suspend and Standby in OnNow as there was previously under APM definitions" (Microsoft) Office Equipment: The “Standby” Problem
