Do you like having a second screen with your computer setup? What if your laptop could carry a second screen for you? That’s the idea behind Lenovo’s latest proof of concept, the ThinkBook Modular AI PC, announced at Mobile World Congress in Barcelona.Lenovo is never shy to show off wacky, weird concept laptops. We’ve seen a PC with a transparent screen, one with a rollable OLED screen, a swiveling screen, and another with a flippy screen. At CES earlier this year, the company showed off a gaming laptop with a display that expands at the push of a button. Sometimes, these concepts turn into real products that go on sale (often in limited quantities).At MWC 2026, Lenovo trotted out three concepts. While it’s unclear whether any of them will become real, purchasable products, there’s some unique utility here, and a peek at how computing experiences could change in the future.A Laptop With a Built-In Portable ScreenThe ThinkBook Modular AI PC has a second screen hanging magnetically off the back of the laptop, and it can show content to people sitting in front of you.
