You can always count on Lenovo to show up at a tech conference with a cool laptop concept or two. HAS CES 2026we glimpsed the Legion Pro Rollable Laptop with a screen that expands laterally and the ThinkPad Rollable XD Laptop with a display that extends upwards. And now, not even two months later, Lenovo is showing off 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 features a removable secondary display that creates several different ways to divide up your work.
In addition to this latest laptop concept, Lenovo announced a number of products at MWC that will ship this year. I’ll return to the other laptop updates on the show, but first, let’s take a look at Lenovo’s awesome, modular ThinkBook concept.
ThinkBook Modular AI PC Concept
This ThinkBook concept looks like a typical laptop, except it has an additional screen on the outward-facing top cover. Each screen is a 14-inch panel, but the secondary screen can be detached and deployed in different ways.
With the secondary display attached to the laptop’s top cover behind the primary display, you have the best way to transport the ThinkBook in transit. This back-to-back display arrangement can be used to present to someone sitting across from you: whatever you see on the screen in front of you, they can see on the screen in front of them.
The other two display modes are more useful:
1. Remove the keyboard (yes, the keyboard comes off too), swap the second screen in its place and you get 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 install it next to the laptop as a second display on the side, just as you would with a portable monitor. The removable kickstand, hidden in plain sight at the bottom of the laptop, magnetically attaches to the screen to support it in landscape or portrait mode. You’ll need to use the included cable to connect the display to the laptop, which creates some bulk, but it’s still a useful setup for those busy times of the day when you need to keep an eye on more things than can fit on a single 14-inch screen.
With the detachable Bluetooth keyboard, you can use the ThinkBook Modular AI PC with its two screens arranged vertically side by side.

Additional modularity comes from the ThinkBook’s ports. Ports include USB-A, USB-C, and HDMI; these can be exchanged for each other. A bay is located on either side of the laptop for these modular ports, and the extras are housed in a small AirPod-like case.
The ThinkBook Modular AI PC has modular ports that you can swap.
Josh Goldman/CNETThis is a dual-screen laptop concept that I’d really like to see because you don’t pay a weight penalty to benefit from the versatility of this modular design. Many dual-screen laptops are so heavy that I’d rather just have a desktop with two monitors.
But with the ThinkBook Modular AI PC concept, it’s as portable as most 14-inch laptops, weighing just 3 pounds. The detachable screen is so thin and light that I thought it was just a mockup when I first picked it up and not a real working screen.
My only notes would be to encourage Lenovo to reinforce the kickstand on the back of the modular display. It’s too puny to provide a solid basis for the display. And I would like a little rubber button on the end so it doesn’t slide around so easily.
The kickstand is a little too fragile.
Josh Goldman/CNETThinkPad updates also focus on serviceability
Lenovo announced a series of ThinkPad laptop updates at MWC, and modularity appears in a few of them. In the ThinkPad T-series laptop and ThinkTab X11 tablet, Lenovo introduced a battery that can be removed without tools for better serviceability. Just press two tabs and the battery comes out immediately. ThinkPad T-series laptops also feature easier-to-remove bottom panels, a simplified internal layout, and user-replaceable USB-C ports.
The ThinkPad T14 Gen 7 features up to 14-inch 2.8K OLED display powered by the latest Intel and AMD processors. The ThinkPad T14 weighs almost 3 pounds, or 2.8 pounds, according to Lenovo. The thinner ThinkPad T14 weighs less than 2.5 pounds, which is exceptionally light for a 14-inch laptop.
Stop the presses! Is this a ThinkPad in a color other than black?
Josh Goldman/CNETIn 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’s actually navy blue in color.
But if you think the keyboard will also get the Cosmic Blue treatment, you’ll be disappointed to know that the keys remain basic ThinkPad black.
Both ThinkPad T-series laptops will be released in the second quarter, with the ThinkPad T14 starting at $1,799 and the ThinkPad T14 starting at $1,899.
Meanwhile, the ThinkTab X11 is a rugged Android tablet with an 11-inch 2.5K display and powered by a Qualcomm Snapdragon
We’ll have to wait until the second half of the year for the detachable ThinkPad X13.
Josh Goldman/CNETLenovo also introduced a larger, less robust tablet in the ThinkPad X13 detachable. It has a 13-inch screen that you can detach from the keyboard for a true tablet experience. Its battery and USB-C ports are also user-replaceable, once again showing Lenovo’s focus on repairability and product longevity. The ThinkPad X13 detachable will only be available in the third quarter, starting at $1,999.
