NEC has announced a new ultrabook today called the LaVie Z that claims to be the world's lightest with a weight of 875 g. NEC used a new alloy for the first time made from a lithium-magnesium die casting process to make the ultrabook thin and lightweight. Despite how light the machine is it still has a 13.3-inch display.
The special lithium-magnesium die casting process allows NEC to integrate the display enclosure housing to the display directly making for a narrow frame that is thinner and weighs less. The keyboard housing is also integrated into the design. The body is 14.9 mm thick at its thickest part. The machine uses a battery that can recharge to 80% capacity in one hour.
Other features include the ability to boot in about two seconds from sleep mode using Quick Power On feature. The display has a resolution of 1600 x 900, and the machine uses a Network Duet feature to share data storage space with another machine on the network. The ultrabook can be had with either a Core i7-3517U processor and 256 GB of SSD storage or a Core i5-3317U with 128 GB of SSD storage. Both versions use 4 GB of RAM and promise 8.1 hours run time per battery charge. The machines also feature integrated Bluetooth, Wi-Fi, and a 720p webcam. The ultrabook will launch on August 23 at an undisclosed price.
