The 13-inch U310 and the 14-inch U410 are between 18 mm and 21 mm thick and weigh 3.7 and 4.2 lbs, respectively.
Due to their mainstream focus, both models compromise on mass storage and use a hybrid HDD-SSD solution rather than a solid state drive alone. Lenovo chose to use 500 GB and 1 TB HDDs and a 32 GB SSD to serve as data cache that support fast-boot and fast-resume.
The systems are available with Ivy Bridge i3, i5 and i7 processors, Intel's WiDi technology, Dolby Home Theatre v4 sound, and Nvidia discrete graphics. Prices start at $750 for the U310 and at $800 for the U410.
