HP ENVY

Released on October 15, 2009.^[1] All models have a standard battery that fits in the chassis as well as an optional slice battery that fits below the chassis, in each case promised by HP to more than double the battery life. Both machines are also constructed from layered magnesium and aluminum etched with a subtle design pattern. The slice battery adds about 1.5 inches to the laptop's height and a pound and a half. However, it more than doubles the battery life. The AC adapter is also of considerable size since it must power and charge the slice and battery in the laptop.
