Fujitsu Claims 634-gram 14-inch Core I7 Laptop Is World's Lightest

Fujitsu Japan's client computing operation claims to have seized the title of world's lightest laptop, after launching the 634-gram "FMV Zero."

Manufacturers' attempts to make lightweight laptops have often resulted in compromised bills of materials. Not so with the FMV Zero, which boasts a 14-inch WUXGA (1920 x 1200) LCD.

Under the hood you'll find a Core Ultra 5 125U or Core Ultra 7 155U processor, depending on your whims. Both are Meteor Lake parts built on the Intel 4 process and launched in Q4 of 2023. Memory options range from 8GB to 64GB, and solid state disks can be had in 256GB, 512GB, 1TB or 2TB. Sadly, Fujitsu's product page and build-to-order facility doesn't update the machine's weight as you change components.

The one item Fujitsu has skimped on is the battery, which stores just 31Wh – meaning the machine is rated for six hours of unplugged operations. A weightier model that tips the scales at a back-breaking 888 grams has a 64Wh powerpack. Both models measure 308.8 × 209 × 15.8～17.3mm, with the thickness figures reflecting the tapered shape typical of most laptops.

Physical connectivity comes courtesy from an RJ45 socket, a pair of USB-A ports, a sole USB-C connector, a microSD slot, and an HDMI connection. Wi-Fi 7 and Bluetooth 5.4 handle wireless comms.

The base configuration costs ¥197,000 ($1,300), but maxing out processor, memory, and storage specs more than doubles the price.

If you're keen to buy it, the machine is only sold at WebMart – Fujitsu Japan's online store.

Those of you imagining you might be able to scoop one on a trip to Japan will need to plan carefully. Fujitsu's site advises a month-long delay before delivering, and hardware options add further waits of two or more weeks. The Register waded through the purchase process – but stopped when registration was required, so can't say if Fujitsu will deliver to a hotel.

And given the brand has quit Europe's PC market, the chance of these featherweights reaching a wider set of Reg readers appears slim – although the machines' use of a keyboard that doesn't offer Japanese kana notation means one less thing for English speakers to worry about.

Fujitsu is not alone in making sub-1kg laptops, but dipping beneath 650 grams does appear to be a realm only the Japanese giant has entered. ®
