We recently reported on a Lenovo MWC leak that claimed Lenovo would show off a Legion Go Fold at Mobile World Conference in Barcelona in early March. Now, a new leak shared by evleaks on X has shown off what Lenovo will apparently call the “ThinkBook Modular AI PC Concept.” The leaker didn’t provide much information other than the name and two images of the device, but the combination of the word “modular” in the name and the clues from the images provide a pretty clear idea of what’s going on.
From the looks of it, the ThinkBook concept will have a traditional clamshell design, but the space where the keyboard deck would usually be on a traditional laptop will instead be a space for modular accessories. The accessories shown off in the leaked renders of the device are a laptop keyboard and a display equal in size to the main display in the top of the clamshell. This looks to be an iteration of devices like the Lenovo ThinkBook Flip, although the ThinkBook Modular AI PC Concept could achieve a similar effect, especially in terms of screen real-estate and possibly ergonomics, although likely with significantly lower costs, thanks to a simpler design without a flexible OLED panel. The new concept would also offer users more flexibility—you could just leave the lower display at home or pack both displays and a mechanical keyboard and mouse for better ergonomics and all the other benefits better peripherals offer.
