Hewlett-Packard has announced the availability of its latest Pavilion laptop with Google's Chrome OS as the PC maker tries to improve laptop sales by offering an alternative to the Windows OS. The Pavilion 14 Chromebook has a 14-inch screen and runs on a dual-core Intel processor. The laptop is roughly 21 millimeters thick, and weighs 1.8 kilograms. It offers just over four hours of battery life, said David Conrad, director for product management at HP's consumer products group.
