Lenovo just unveiled new laptops within the ThinkPad L-Series, the L390 and L390 Yoga models. Both laptops are expected to pass the Mil-Specs (military specifications) test and they’re destined for business users and people who “work in the field”.

L390 is a follow-up to the appreciated ThinkPad L380 and it starts at $659, while the Yoga version starts at $889. Both units can be configured with 32 GB of RAM and 512 GB of SSD storage. The CPU options go up to an Intel Core i7 7th gen and there’s also at least a Core i5 version. The ThinkPad L390 is a 3.2 pound notebook, that uses a 13.3 inch Full HD touchscreen display, with a 180 degree hinge.

The L390 Yoga is a 3.5 pound convertible with pen support and a 360 degree hinge. They have Whiskey Lake CPUs inside, which should offer a small boost compared to the Kaby Lake-R chips, while also supporting Gigabit WiFi. Both units are expected to come this month, being available in stores already.

Both models have USB Type-C ports, two USB 3.1 Type-A ports, HDMI 1.4 ports and mini Ethernet ones, as well as a microSD card slot. Both pack 45 Whr batteries, even though Lenovo estimates that you’ll get up to 2 hours longer battery life for the non convertible model. Color versions are black and silver. The convertible one has the Lenovo Active Pen, that gets a special slot in the computer, when it’s not being used.
