Energy Usage Research on Laptops and MacBooks

Although there are many articles and published papers on energy consumption related to computer equipment, it’s almost impossible to find detailed specifications of this equipment. Here, you will find both: actual measurements (not averages or estimates) and also the specifications of the devices, which can help with comparison and identification.
Please note: More devices are added monthly, so please make sure to keep tuning in.

Parameters

  • Testing Procedures:
    – Devices with an Operating System (Desktops, Laptops, etc) were monitored in different states as the Operating System is able to use technology such as SpeedStep and Cool’N’Quiet. These modes in particular were measured:
    * Within BIOS: No power saving technology implemented – Computer was left at BIOS screen
    * Within OS – Balanced, Power Saver, or Degrade (XP): Windows is allowed to manage the processor speed as required by the OS – These are the names of power profiles as used by older and newer versions of Windows. The frequency may also be noted next to the power reading.
    Note: When no power profile is specified, it is assumed Balanced or Power Saver is in use by default
    * Within OS – None (XP) or High Performance: Windows applies no power saving technology and allows CPU to run at full speed
    * Stand by or Hibernate – Computer set to sleep or standby typically using S3/S4 states
    * Off: The computer has been completely shut down but still plugged into the wall
    * Live CD – Helps to see a comparison between Windows and Linux Live CDs power consumption
    * Benchmark or stress test – Performed gaming or applications such as Prime95, HeavyLoad, CPU Stability Test or Folding@home; as a stress test is performed, this raises energy consumption of the computer to maximum
    – For other Devices with no Operating System with power saving technology capabilities (TVs, Modems, Routers, etc), these were allowed to run and operate normally as the power measurement was taken
