Lenovo Unveils a 'Build-It-Yourself' Laptop: Ports You Can Swap with Your Fingers and a Second Screen You Can 'Tear Off' and Put on Your Desk

At the MWC 2026 trade show, Lenovo didn't just stick to updating its business lineups. As per tradition, they also unveiled two concept devices that are, to say the least, unconventional. We're talking about the modular ThinkBook and the 'three-dimensional' Yoga Book. The first one aims to solve the eternal dilemma of choosing between ultra-portability and functionality, while the second tries to make 3D technology practical for designers.

The ThinkBook Modular AI PC Concept is hard to define as a laptop in the classic sense; it's more of a building kit. This laptop features a second display that attaches to the back of the lid with magnets, looking like part of the cover until you take it off. In reality, it's a fully autonomous and incredibly thin screen. You can remove the standard keyboard (it's wireless) and place this display in its spot, creating a vertical dual-screen setup. Alternatively, you can use it as a standalone monitor via USB-C, especially since a magnetic stand is included in the package.

The connectivity ports on this model are also modular. If you need to move the HDMI port to the other side or swap out a port entirely, you simply switch the modules around. For carrying these 'spare' connectors, there's a case that looks just like a wireless earbuds charging case. From the looks of it, this is one of the most thoughtfully designed concepts Lenovo has come up with in recent years.

The second concept (the Yoga Book Pro 3D) targets a more specific audience. It's a laptop built for 3D modelers and designers who work with spatial objects. The device comes with two PureSight Pro OLED screens, and the top one can display images in 3D without needing special glasses. This is achieved through AI algorithms that convert flat images into volumetric ones. What's more, the neural network can build out the environment around an object, turning a simple model into a finished scene.

Users can control the models with gestures, which are tracked by a built-in infrared camera. Meanwhile, the bottom screen acts as a control panel. You can place 'clothespin' style sliders on it to adjust lighting, viewing angles, or tones, keeping the main 3D display free of interface clutter. The concept packs serious hardware: an Intel Core Ultra 7 processor and a GeForce RTX 5070 graphics card. Lenovo believes demand for such devices will grow; they project the market for 3D displays will triple by 2032.

Both devices currently exist in a "look what we can do" status. There are no prices or release dates. However, while the ThinkBook looks almost ready for production, the Yoga Book Pro 3D seems more like an attempt to gauge interest and figure out if designers actually need a portable 3D screen.

So, would you find the ability to move ports from one side of your laptop to the other actually handy, or is it just a cool but useless feature? Let us know in the comments.
