energy saving PC

Indian-American helps design energy-saving PCs

Personal computers may soon save large amounts of energy by "sleep talking".

Doctoral researcher Yuvraj Agarwal of the University of California San Diego (UCSD) in collaboration with computer scientists has created a plug-and-play hardware prototype for personal computers (PCs) that induces a new energy saving state known as "sleep talking".

Normally PCs can be in 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.
