Fujitsu unveils 1.7-pound 13-inch notebook
Fujitsu yesterday unveiled possibly the world's lightest 13-inch notebooks: The LifeBook UH75/B1 is a consumer notebook which weighs a feather-light 1.72 lbs (777g) The business model, the U937/P, weighs 1.76 lbs (799g). In comparison, the Lenovo LaVie Z and LG Gram 13 weigh 1.87 lbs (848g) and 2.16 lbs (980g), respectively.
How did Fujitsu get these laptops so incredibly light? Part of it is the material: the consumer model is made from magnesium-lithium alloy—a material that weighs only half as much as aluminum—while the business model is standard magnesium alloy and so is a bit heavier. However, much of the weight cut is also from a small battery. To get these laptops at their lightest weight possible, you'll need to order them with a tiny 25 Wh battery. However, there is the option of a larger 50 Wh battery. Fujitsu notes that the higher-capacity model weighs just over 2 lbs (913g)—but makes up for that extra weight with an alleged 17 hours of battery life.
The LifeBooks will sport Intel Core i5-7200U CPUs, a fingerprint sensor, and a full array of ports, including HDMI, Ethernet, and USB 3.0 (2 x Type-A, 1 x Type-C). There is no word yet on whether the notebooks will be available outside of Japan.
