For a computer to receive an Energy star certification, which element needs to meet the specified requirements?

Question

Options

• APower density
• BPower management
• CPower source

• A
  6% (3)
• B
  89% (42)
• C
  4% (2)

Explanation

Power management is the correct answer because Energy Star certification for computers requires that the device meets specific criteria for how it handles power consumption during idle and inactive periods - such as automatically entering sleep or low-power states after a set time. These requirements ensure the device actively reduces energy use rather than simply consuming less at peak load.

Power density (A) is a measure of power per unit area or volume, more commonly referenced in data center and server efficiency discussions - it is not a criterion in the standard Energy Star computer certification framework. Power source (C) refers to where a device draws electricity from (e.g., AC outlet, battery), which Energy Star does not mandate; it focuses on how efficiently a device uses whatever source it has.

Memory tip: Link "Energy Star" to "Sleep Timer Activation Requirements" - Energy Star rewards computers that automatically manage their power down to a sleep state, making management the key word to remember.
