With a dedicated AI engine, the ThinkBook 13x Gen 4 offers adaptive performance while enabling you to unlock new AI experiences to boost your productivity.

Portable style you’ll want to take everywhere
Ultrathin and ultralight, the ThinkBook 13x Gen 4 is ultra-easy to take with you anywhere — and you’ll want to show it off wherever you go. Its exquisite aluminum design and dual-tone Luna Grey cover will make an impression, as will the esthetically pleasing edge-to-edge keyboard. Or opt for the Special Edition, constructed from corrosion-resistant stainless magnesium and finished in a patterned dual-tone Seashell colour.

Superlong battery life
Forgot your charger? No problem! The ThinkBook 13x Gen 4 can last all day with the largest-capacity battery ever in a 13" laptop. Its power usage is streamlined, thanks to an ultralow-power display panel with attention- and presence-based brightness and refresh rate, plus AI-enhanced battery optimization. And with WiFi 6e and three blisteringly fast Thunderbolt™ 4 ports, connectivity won’t be an issue, either.

Keeps you and your data private
Rest easy with the protection of the ThinkBook 13x Gen 4 laptop’s biometrics — from a fingerprint reader integrated with the power button, to facial recognition software that works with the infrared (IR) camera. ThinkShield, our comprehensive suite of security solutions, ensures your system is protected. A discrete Trusted Platform Module (dTPM) encrypts your data, and a webcam privacy shutter ensures you won’t appear on-camera unless you want to.

A rich audiovisual experience
Supernarrow bezels give the ThinkBook 13x Gen 4 laptop a 97% screen-to-body ratio — an industry first in 13" devices. Between this and its 3:2 aspect ratio, the 13.5" display is actually larger than a 14" display in 16:9. Visuals are stunning in superhigh brightness and Dolby Vision®, with a fast adaptive refresh rate. It’s also Eyesafe® low blue-light certified, helping to protect your vision. Four Harman Kardon® speakers with Dolby Atmos® yield incredible sound in addition to the visuals.

Flexible expansion with Lenovo Magic Bay

Adapt and enhance your PC experience with this ecosystem of ultraportable, detachable modules — including Lenovo Magic Bay Light, Lenovo Magic Bay LTE, and Lenovo Magic Bay 4K Webcam.
