Elevated performance & on-the-go productivity
The Lenovo ThinkBook 13x Gen 4 (13" Intel) laptop features the business-class performance of Intel® Core™ Ultra processors and the Lenovo LA3 AI chip. Laptops powered by Intel® Core™ Ultra offer high productivity and amazing AI experiences without lags or battery drain. The processors are optimized for multitasking in productivity apps while on the go. Easily create content, upload huge files, and video conference with colleagues without slowing down — all while unplugged. Get battery life like you’ve never known, lasting up to a full day between charges.

Built to never compromise
As an Intel® Evo™ Edition laptop, the ThinkBook 13x Gen 4 was designed to do everything you need. Experience all-day battery life, less than one-second instant wake, and best-in-class connectivity. Plus, with Intel® Unison™ 2.0, you can sync your laptop with any iOS or Android smartphone to keep you in your flow without switching devices. Call or text without reaching for your phone — and transfer files, photos and videos with ease.

Let AI accelerate your experiences
Create images or music from text. Improve photos or videos in a few clicks. And more. With more than 100 AI experiences possible, your favorite AI-accelerated software runs exceptionally well. 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. Enjoy more AI-accelerated experiences, while enabling performance optimization and power savings resulting from putting the right workload on the right engine.

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
The future of work is about people, not places. Lenovo Magic Bay Accessories provide an all-new computing experience for professionals on the move. 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. And watch CES ‘24 for Lenovo Magic Bay Studio — a 4K camera and speaker exclusive to the ThinkBook 13x Gen 4. Attach the module of your choice via seamless pogo pin connectivity and you’re ready for any hybrid work situation.
