Sleep Talking PCs Save Energy and Money
San Diego, CA, April 23, 2009 — Personal computers may soon save large amounts of energy by “sleep talking.” Computer scientists at UC San Diego and Microsoft Research have created a plug-and-play hardware prototype for personal computers that induces a new energy saving state known as “sleep talking.” Normally PCs can be in either awake mode—where they consume power even if they are not being used—or in a low power sleep mode—where they save substantial power but are essentially inactive and unresponsive to network traffic. The new sleep talking state provides much of the energy savings of sleep mode and some of the network-and-Internet-connected convenience of awake mode.
