At A Glance

The U31Jg is ideal for getting work done on the road, but movie and music buffs should look elsewhere.

Manufacturer’s Description

With its supercharged performance, the ASUS Super Hybrid Engine boosts the U31JG notebook performance up to 15 percent in demanding tasks, thanks to its dynamic overclocking technology. It's not simply about cranking up the CPU though, ASUS engineers have specifically tuned several system-wide values to optimise the performance gains for the energy used, and Super Hybrid Engine is designed to work specifically on Intel Core i3, i5 mobility processors! The Super Hybrid Engine boosts performance only when required by CPU-intensive tasks, like games and high definition movies, without sacrificing any stability and reliability.
