Sony's VAIO SA Laptop
Sony’s VAIO SA ultrathin laptop touts a 13.3-inch screen, up to 12 hours of battery life, and both Intel Core i7 and AMD Radeon HD 6630M GPU. But it’s clear the portable PC was also built with power efficiency in mind, especially when you look closely at its keyboard.
The Windows 7-based notebook comes equipped with a full backlit keyboard that seems to have a mind of its own. Its light fades after a period of idleness, conserving energy when it’s not needed and automatically adjusting itself to produce only the amount of light needed to be visible in a certain environment.
Put simply, the SA series "knows" when a user is in a brightly-lit environment and dims itself automatically to save power.
Sony has also partnered with IBM’s World Community Grid to donate the processing power of Sony VAIO PCs during idle time to fuel research of global environmental issues, AIDS, cancer, and muscular dystrophy.
