You can always count on Lenovo to show up at a tech conference with a cool laptop concept or two. At CES 2026, we glimpsed the Legion Pro Rollable laptop with a display that expands sideways and the ThinkPad Rollable XD laptop with a display that extends upward. And now, not even two months later, Lenovo has another laptop display concept at Mobile World Congress 2026: the ThinkBook Modular AI PC Concept.
Instead of a rollable or foldable display, this ThinkBook concept has a detachable secondary display that creates a couple of different ways to spread out your work.
In addition to this latest laptop concept, Lenovo announced a number of products at MWC that will ship this year. I’ll get to the other laptop updates from the show, but first, let’s get our heads around Lenovo’s funky, modular ThinkBook concept.
ThinkBook Modular AI PC Concept
This ThinkBook concept looks like a typical laptop, except that it has an extra display on the top cover that faces outward. Each display is a 14-inch panel, but the secondary display can be detached and deployed in a few different ways.
With the secondary display attached to the laptop’s top cover on the back of the primary display, you’ve got the best way to carry the ThinkBook in transit. This back-to-back display arrangement can be used to present to someone sitting across from you — whatever you’re seeing on the screen facing you, they can see on the screen facing them.
More useful are the other two display modes:
1. Remove the keyboard (yes, the keyboard comes off, too), swap the second display in its place, and you’ve got a dual-screen laptop with double the workspace. The detachable keyboard has Bluetooth, so you can use it in this dual-screen mode.
2. Remove the rear secondary display, then set it up next to the laptop as a second screen off to the side, as you would with a portable monitor. The removable kickstand, hidden in plain sight on the bottom of the laptop, magnetically attaches to the display to prop it up in either landscape or portrait mode. You’ll need to use the included cable to connect the display to the laptop, which creates some clutter, but it’s still a useful setup for those busy times of day when you need to keep an eye on more things than will fit on a single 14-inch screen.
With the detachable Bluetooth keyboard, you can use the ThinkBook Modular AI PC with both of its displays arranged vertically side by side.
The keyboard and secondary display connect via pogo pins that Lenovo has favored for its Magic Bay ecosystem of swappable accessories. Each is easy to swap in and out, and they create a satisfying connection when snapped into place.
Additional modularity comes by way of the ThinkBook’s ports. The ports include USB-A, USB-C and HDMI; these can be exchanged for one another. A bay is located on each side of the laptop for these modular ports, and the extras are housed in a small AirPod-like case.

This is one dual-screen laptop concept that I would really like to see because you aren’t paying a penalty in weight to gain the versatility of this modular design. Many dual-screen laptops are so heavy that I’d rather just have a desktop with two monitors instead.
But with the ThinkBook Modular AI PC Concept, it’s as portable as most 14-inch laptops, weighing just 3 pounds. The detachable display is so thin and light that I thought it was just a mockup when I first picked it up and not an actual operational display.
My only notes would be to encourage Lenovo to strengthen the kickstand on the back of the modular display. It’s too puny to provide a solid base for the display. And I’d like a little rubber nub on the end of it so it doesn’t slide around so easily.
The kickstand is a bit too flimsy.
ThinkPad updates also include a focus on serviceability
Lenovo announced a slew of ThinkPad laptop updates at MWC, and modularity shows up in a couple of them. In both the ThinkPad T series laptop and ThinkTab X11 tablet, Lenovo has introduced a battery that can be removed without tools for greater serviceability. Just press two tabs, and the battery comes right out. The ThinkPad T series laptops also feature bottom panels that are easier to remove, simplified internal layouts and user-replaceable USB-C ports.
The ThinkPad T14 Gen 7 features up to a 14-inch 2.8K OLED display powered by the latest Intel and AMD processors. The ThinkPad T14 weighs close to 3 pounds — 2.8 pounds, according to Lenovo. The slimmer ThinkPad T14s weighs less than 2.5 pounds, which is exceptionally light for a 14-inch laptop.
Stop the presses! Is that a ThinkPad in a color other than black?
In a major shakeup for a ThinkPad, the ThinkPad T14 will be available in a color other than black. You can get it in Cosmic Blue, which is a blue so dark it might as well be black. But, hey, when the light catches it just right, you can see that it is, in fact, navy blue in color.
But if you think that the keyboard will also get the Cosmic Blue treatment, you’ll be disappointed to know that the keys remain a basic, ThinkPad black.
Both ThinkPad T series laptops will start shipping in Q2, with the ThinkPad T14 starting at $1,799 and the ThinkPad T14s starting at $1,899.
Meanwhile, the ThinkTab X11 is a rugged Android tablet featuring an 11-inch 2.5K display and is powered by a Qualcomm Snapdragon X series CPU. It’s expected to be available in Q2, starting at $499.
You’ll need to wait until the second half of the year for the ThinkPad X13 Detachable.
Lenovo also introduced a larger, less rugged tablet in the ThinkPad X13 Detachable. It has a 13-inch display that you can detach from the keyboard for a true tablet experience. Its battery and USB-C ports are also user-replaceable, again showing Lenovo’s focus on repairability and product longevity. The ThinkPad X13 Detachable won’t start shipping until Q3, starting at $1,999.
