Ahead of CES this year, Lenovo refreshed its lineup of ThinkPads with eighth-generation U-series processors. The new PCs come with a built-in privacy guard for the camera, USB Type-C charging that's designed for mechanical docking, and more.

The ThinkPad T480 is considered to be the workhorse of the lineup. With a somewhat rugged design, users can hot swap the battery. There's an internal 24Wh battery, and an additional battery that comes in 24Wh, 48Wh, and 72Wh sizes. As long as that internal battery has a charge, you can swap out the external one without ever turning off the device.
