The world’s lightest laptop is lighter than nothing Apple iPad Pro


The laptop comes with a 12-generation Intel Core processor (either 1235U or 1255U) and 8GB, 16GB or 32GB LPDDR4x memory (dual channel and soldered onboard. Onboard storage ranges from 256GB to 2TB and there’s even an option for an external optical drive, still a common thing in Japan. The display is a whopping 13.3-inch full HD matte display with a HD webcam at the top with a privacy shutter. Wireless connectivity is achieved via an Intel AX201 chipset that delivers Bluetooth 5.1 and WiFi-6.

One corner has been cut though, and disappointingly, it’s battery capacity. At 25WHr, it’s about a quarter of what you will find on some heavier rivals, but that’s perfectly acceptable given the fact that you should in theory be able to trickle charge it using a phone charger or even an emergency power bank. Surprisingly, the manufacturer quotes an estimated battery life of 11 hours, which we feel is highly unlikely.

One unexpected freebie is a three-year warranty and a three-year subscription to McAfee Livesafe security software. That goes towards sweetening the rather steep price of 317,222 yen (about £1950, $2,400, AU$3,400) for its top of the range model (Core i7, 32GB RAM, 2TB SSD, Windows 11 Pro). We have asked Fujitsu for a sample for a review and will update this post if we hear anything from them.

Story Highlights

  • The ridiculously light Lifebook WU-X/G2 from Fujitsu weights only 634g. The lightest laptop in the world has been secretly released by Fujitsu, although it is now only available in Japan. The WU-X/G2 is a member of the company’s Lifebook line and weighs just 634g (or 22.4 ounces and a little under 1.4 pounds) when uncharged. It indicates that this business laptop is lighter than the 682g Apple iPad Pro 12.9 tablet. At 307 x 197 x 15.5mm, it is somewhat huge, allowing for a larger screen, greater connectivity, and, dare we say it, a nicer keyboard with a large Enter key and tactile buttons on its touchpad. Size-wise, it is straightforward.

  • Despite its weight, the WU-X/G2 has a full array of ports that would put laptops weighing two or three times more to shame. There’s one card reader, three USB ports, a full size HDMI port and even a Gigabit Ethernet port plus the power button doubles as a fingerprint reader. No need for a laptop docking station. Sadly, Fujitsu didn’t resort to any magic tricks to achieve so much weight saving, instead using carbon fiber as the main material for its chassis.
