- Lenovo unveiled modular proof of concept ThinkBook at Mobile World Congress 2026.
- It features a detachable dual screen and keyboard and swappable ports.
- Although it’s still in development, it looks like Lenovo is close to a finished product.
Lenovo is showing off some serious conceptual muscle with its proof-of-concept PC. Last year, I tested the ThinkBook Plus Gen 6 Rollable and found its 17-inch rollable screen to be surprisingly practical—if not entirely polished.

Now at Mobile World Congress, Lenovo unveiled a concept that’s even more ambitious: the ThinkBook Modular AI PC, a dual-screen laptop with a detachable display, keyboard, and mix-and-match I/O ports for a fully customizable workstation that changes shape in multiple configurations.
Lenovo has really been moving toward a modular laptop over the past few years, but this model may be the most serious commitment yet to the idea with a mainstream 14-inch laptop that feels surprisingly close to a finished product, even if there are still some hiccups.
disassemble and replace
By default, the laptop’s second display resides behind the main display, but it can be turned off to take the place of the keyboard or propped up next to the laptop like a standalone portable monitor.
If you want to use it as a standalone external monitor, there’s a built-in kickstand on the back that allows the monitor to be propped up in landscape or portrait mode. However, keep in mind that you have to keep it connected to the laptop only with a USB-C cable.

In my dealings with the kickstand, I found it a bit awkward and difficult to maneuver, and it’s one of the weaker physical elements of the laptop’s design, but probably one of the easiest for engineers to improve.
Similarly, the keyboard/trackpad is also completely detachable and can be placed anywhere using Bluetooth to stay connected. It’s similar to the design we saw on the ZenBook Duo – easy to use but a little awkward, freeing up placement on your desk. I still wish there was a snap-to mechanism that attaches it to the bottom of the laptop.
modular i/o
Although the swappable display and keyboard is nice, personally what I found most interesting were the swappable ports, which show a level of modularity we haven’t yet seen on Lenovo’s mainstream laptop line. Only the Framework laptops (the 16-inch is one of my favorite laptops of last year) have this type of swap-and-go I/O, so it’s notable in a Thinkbook.
While the Framework’s ports are plastic modular ports that all connect via integrated USB-C connections, however, the ThinkBook’s I/O is not. Additionally, the port type is also more limited, with only USB-C, USB-A, and HDMI available so far.

Still, being able to take the ports out and swap sides if you need HDMI on the right, or a charger on the left, is infinitely convenient and reflects a more flexible device concept.
The ThinkBook Modular AI PC is a big step in an exciting direction, and although it’s a conceptual device with no release date, it looks like Lenovo is on to something here. After all, it’s just a ThinkBook chassis with some special adjustments to the form factor here.
Lenovo made an indirect statement at CES on its commitment to taking modularity and repairability seriously with the ThinkPad X1 Carbon Gen 14 Aura Edition. That laptop saw a redesigned, double-sided motherboard to improve accessibility and part replacement for the end user, and was also featured on the flagship laptop lineup no less.
Next, I hope Lenovo continues to replicate these ideas and put them into mainstream laptops like ThinkPads and Yogas. There is certainly consumer interest in this.
