Promotional renders suggest Lenovo is reviving its detachable tablet line with the ThinkPad X13 Detachable Gen 1. The leaked images show an "Eclipse Black" device with a 13-inch screen and thinner bezels, representing a clear size upgrade over the prior X12 model. This positions it directly against Microsoft's Surface Pro 11 and 12.

Web sleuths analyzing the renders focused on USB-C ports marked with lightning bolt symbols, a strong indicator of Thunderbolt 4 support. This implies the device will use a modern Intel processor, with speculation pointing to a Core Ultra 3 "Panther Lake-H" chip. This would address criticisms that the previous generation's Meteor Lake CPUs were underpowered for a professional device.

The leak confirms Lenovo has preserved core ThinkPad hallmarks for this form factor, including the classic keyboard layout, a TrackPoint nub, physical mouse buttons, and a circular fingerprint reader. These features are critical for its professional audience. The device is now anticipated to debut at MWC 2026 in Barcelona from March 2 to 5.

This leak signals Lenovo's intent to seriously compete in the premium detachable market by combining a larger, modern display with expected Thunderbolt 4 performance and the beloved, productivity-focused input features that define the ThinkPad brand.
