Lenovo's Modular ThinkBook AI Concept Leaks Ahead of MWC 2026

Just days after Lenovo's Legion Go Fold concept with its massive 11.6-inch screen made waves, the tech giant appears to be preparing an even more ambitious modular laptop concept for Mobile World Congress 2026.

What We Know So Far

According to reliable industry tipster Evan Blass, Lenovo is developing a modular laptop concept likely to be branded as the "ThinkBook Modular AI PC." The leak consists of only two images shared via X/Twitter, with no accompanying specifications or technical details.

Design Analysis

The images reveal what appears to be a traditional clamshell design with a twist. The top half houses what seems to be a standard display, while the bottom section appears to function as a modular hub for accessories.

In the first image, the display has been detached and moved to the side, with a traditional keyboard taking its place. The second image shows a secondary display where a keyboard would typically rest, suggesting a highly flexible configuration system.

This modular approach could allow users to swap between different input methods, displays, or even specialized hardware modules depending on their needs. The AI branding in the rumored name hints at potential on-device AI processing capabilities or specialized AI-focused components.

Context and Competition

Lenovo has been pushing the boundaries of laptop design recently, with their Legion Go handheld gaming device and now these concept devices. The modular approach positions Lenovo against other innovative laptop designs like Framework's upgradeable laptops and Dell's Concept Luna sustainable design.

What to Expect at MWC 2026

With Mobile World Congress just around the corner, laptop enthusiasts won't have to wait long to learn more about Lenovo's modular ambitions. The company is expected to officially unveil the concept during the event, potentially revealing:

• Specific modular components and their functions
• AI capabilities and hardware specifications
• Potential release timeline and pricing (if moving beyond concept stage)
• Integration with Lenovo's existing ThinkBook lineup

Industry Implications

If realized, a modular ThinkBook could signal a significant shift in the business laptop market. The ability to customize and upgrade components could extend device lifespans, reduce e-waste, and provide businesses with more flexible computing solutions.

However, modular designs often face challenges with durability, thickness, and cost. Lenovo will need to balance flexibility with the reliability and performance expectations of business users.

Looking Ahead

While release dates and pricing remain unknown, the leak suggests Lenovo is serious about exploring new form factors and functionality in the business laptop segment. The ThinkBook brand, positioned as a more affordable alternative to ThinkPad, could benefit from such innovative features to differentiate itself in an increasingly competitive market.

As MWC 2026 approaches, all eyes will be on Lenovo to see whether this modular concept becomes a reality or remains an intriguing glimpse into potential future directions for business computing.
