High-end laptops are lucky to squeeze 3 hours of run time out of a single charge, and if you're looking for ultra long battery life, your best bet is a netbook. Or is it?
Asus had on display at CES a performance-oriented laptop the company hopes will redefine the high-end genre. The UL80JT, as it's currently called, can switch back and forth between a high-end Nvidia GeForce 310 and Intel's lowly GMA graphics. Combined with a Core i7 CPU capable of re-clocking itself on a second-by-second basis and other micromanagement tricks, Asus claims users can expect up to 12 hours of run time.
Even cooler, the whole process is transparent to the user, meaning you don't have to fiddle with power settings. The laptop decides for itself when to clock the dual-core Core i7 chip up or down and when to switch between graphic chips, and while we're skeptical we'd actually see 12 hours of run time, we would expect the UL80JT to run a lot longer than a typical high end notebook.
