Ultra Low Voltage Notebooks Buying Guide - Buying Guides - Harvey Norman

What Is An Ultra-Low Voltage Notebook?

Ultra-thin notebooks are lightweight, super-slim portable computers that are often referred to as "ULVs" because they are powered by "ultra-low voltage" processors that use less power compared to conventional ones. These processors are deliberately "underclocked", which means that the computer's settings run at a slower rate than usual.

As a result, an ultra-low voltage notebook uses less power than a standard laptop. What this means is that ULVs have a longer battery life; some manufacturers claim that it can last up to eight hours, which is twice as long between charges compared to traditional laptops.

The nature of ultra-low voltage processors – slower timing, lower energy consumption – means they operate under less stress, which makes them more stable and increases hardware longevity.

Why Are ULVs So Light and Compact?

Traditionally, laptops deal with the heat build-up of internal components by using fans and other cooling components. Due to running at a slower rate, ultra-low voltage notebooks generate less heat, to the point where cooling devices are not required. The lack of a fan means these ULVs can run quieter than conventional laptops.

Removing the cooling components frees up weight and space, so ULVs are lighter and thinner. These sleek laptop designs are less than an inch thick and weigh one to 2.5kg, making them very easy to carry. Plus, you still have the flexibility of choosing a full-size screen, ranging from 10 to 16 inches, so that won't compromise usability.

What Are The Benefits Of ULVs?

All these features make ULVs great for travelling light and still providing the power and performance you need for all your music, videos, photos and more.

Combining form and function, an ultra-low voltage notebook promises less weight and longer battery life than a traditional notebook computer, as well as better performance, plus a bigger screen and keyboard than a netbook.
