Dubbed the LG gram series, they can be found at Microsoft stores across the country and online at Microsoft Store and Amazon.

OK, they do not weigh a gram, but it is unlikely the target audience would know what one of those was. The LG gram 14 is among the lightest laptops in the 14-inch category, weighing only 2.16 pounds - less than the 11" MacBook Air. The body is made of carbon-lithium and carbon-magnesium, the same materials found in spacecraft and race cars, and anti-depression pills.

At just a half-inch thin, the LG gram 14 can be packed up and taken anywhere easily.

David VanderWaal, vice president of marketing, LG Electronics USA said that this was an extremely competitive category, and are confident consumers will respond well to this product that combines powerful performance with lightweight design.

It is also being used to show case some of Microsoft's Windows 10. All are Microsoft Signature Edition laptops, which means a clean, fast and protected experience - each PC is free of installed bloatware and has a fully virus-protected system.

There is a choice of fifth generation Intel Core processor (either Intel Core i5 or i7).

It supports the latest standards for connectivity, including Wi-Fi and Bluetooth wireless technology, along with extra ports for USB 3.0, a micro-USB and micro-SD slot. It comes with a built-in HDMI port, which is uncommon among laptops of this size, which generally require HDMI adaptors.

With LG gram's instant boot feature, the operating system starts up immediately when the user opens the display whether it's totally powered off or simply in sleep/hibernation mode. It also boasts a battery life of up to 7.5 hours.

The LG gram series has a 1920 x 1080 resolution screen and 16:9 aspect ratio. The display also features LG's In-Plane Switching (IPS) technology, which ensures accurate colour saturation and contrast, even at wide viewing angles.

"Reader Mode" provides optimal conditions for reading by reducing blue light, helping to protect your eyes and allow for comfortable reading during extended periods of time. LG gram series also offers advanced sound quality thanks to its built-in Digital-to-Analog converter (DAC), which allows users to experience hi-fi quality sound with less noise and distortion.
