Environmentally sound techniques to preserve power

Continuing with the idea of listing every topic of the exam objectives in order to present them as a way to prepare the exam (sort of a personal guide in order to get the certification).

Identify and implement environmentally sound techniques to preserve power.

  • Power management (Power saving features)
    • BIOS settings
      • ACPI
      • Screen brightness
      • Power saving profile
      • Wake on LAN
      • CPU states
        • SpeedStep™(Intel processors)
        • PowerNow!/Cool’n’Quiet™(AMD)
        • LongHaul™ (Via CPU)
        • LongRun™ (Transmeta)
      • Fan speeds
      • Power on and power off timers
    • OS settings
      • Automatic standby after a specified time limit of non-use
      • Hard disk power down time
      • Wireless and Wired NIC power saving settings
      • Sleep, standby, hibernate modes
      • USB Suspend settings
      • PCI Express power management
      • Search and Indexing power saving mode
      • Windows Vista DreamScene™ power setting modes
      • Multimedia Power settings
      • Power utility in control panel
    • IT policy and procedures
      • Shutdown/power off procedures/policies at end of day
      • Shutdown scripts
      • Group policy
    • Consolidation of office equipment
      • Multifunctional devices
      • Power management PCs and lower power servers replace large desktops with energy efficient laptops and thin clients
      • Consolidation of vendors and/or orders to reduce shipping
    • Reduce graphic card performance to minimum requirements
      • Motherboard video output using low 3D performance or power
      • Select GPU based on average wattage or performance/watt
    • No video card – use of shared terminals and thin clients
    • LED monitors and LED lights
    • Use Power over Ethernet (PoE)
    • Wireless AP Auto Transmit Power or Manual Transmit Power
    • Light/power timer on routers and/or networking equipment
    • Active cooling (water or fan) vs. Passive (heatsink only)

This is part of the Green IT Technologies and Techniques domain of the certification.

As said before, this is just a list. As soon as each of the lines gets a blog post it will be linked from here.
