With AMD Ryzen™ 7030 PRO Series Mobile Processors and integrated AMD Radeon™ graphics, plus oodles of memory and storage, it can zip through any task. And with a long-lasting battery, it can run all day.

Designed for your well-being
The ThinkPad L15 Gen 4 laptop makes working from anywhere and videoconferencing a breeze. In addition to a large TrackPad, it has an FHD RGB webcam, user-facing Dolby Audio™ speakers, and Dolby Voice® AI noise-suppressing technology. It also offers, via Lenovo View 3.0, image processing & advanced computer vision framework that enhances camera quality.

All the right connections
Wherever you need to work from, the ThinkPad L15 Gen 4 laptop has got your back. Its array of ports includes USB-C and HDMI, enabling you to connect to the devices and data you need to get the job done. In addition, there’s the option of up to WiFi 6E* and 4G LTE WWAN** connectivity, ensuring Gigabit Internet access from anywhere.

Hardwired security, from inside out
As well as the added security of Microsoft 11 Secured-core PCs, the ThinkPad L15 Gen 3 laptop has layers of ThinkShield protection. This includes an optional FHD + IR hybrid camera that lets you log in with smile and a Power-On touch fingerprint reader for faster access. It also has AMD’s multi-layered safeguards for enterprise-class security and a webcam privacy shutter.

Reliability you can trust
We use the US Department of Defense's MIL-STD 810H standards to ensure that every ThinkPad is reliable and durable. We test against 12 standards and more than 200 quality checks to ensure they run in extreme conditions. These tests cover harsh variables like Arctic wilderness and desert dust storms, including temperature, pressure, humidity, vibration, and more.

Sustainably made & packaged
Every Lenovo device is manufactured using a low-temperature solder process to reduce emissions. By 2025, we’re committed to obtaining 90% of our global operations electricity from renewable sources, to remove one-million tons of greenhouse gas emissions from our supply chain. Meanwhile, this laptop uses plastic-free packaging, with 90% sustainable packaging and is comprised of recycled materials.
