Engineered for the modern workplace
Meet the ThinkCentre M90a Gen 3 all-in-one, a premium desktop PC for today’s work-from-anywhere world. Sleek, secure, and smart, it’s powered by up to 12th Gen Intel® Core™ i9 with Intel vPro® platform and optional NVIDIA® graphics. While its AI noise-suppression and Dolby Atmos® audio enhance your videoconferences, the phone and keyboard docks help save on desk space.

Protecting your data, ideas, & more
With ThinkCentre comes ThinkShield, end-to-end security combining industry-leading hardware, software, and services. The ThinkCentre M90a Gen 3 all-in-one also taps up to Intel vPro® Enterprise for hardware-enhanced PC protection. Other safeguards include BIOS-based Smart USB Protection and an optional physical shutter to close the webcam.

Meetings will never be the same again
With an industry-first tiltable camera and an optional conference call base, every meeting runs more seamlessly. Quad-array far-field microphones, with 360-degree pickup, use AI to suppress annoying background sound. As well as four Harman® speakers, super-fast USB-C connectivity brings even more clarity and richness to your meetings, while a single click fires up Microsoft Teams.

Cooler, quieter, smarter
Thanks to our Intelligent Cooling Engine (ICE) 4.0, the ThinkCentre M90a Gen 3 all-in-one has different power modes based on your computing needs. Boost the power by up to 15%, lower normal system noise by three decibels, or go for maximum cooling. This very modern PC also has optional smart human presence detection that knows when you’re away, enabling a new level of security and energy efficiency.

Pushed to the limit, & then some
As well as our own rigorous in-house tests, the ThinkCentre M90a Gen 3 all-in-one is measured against 12 US military-grade requirements, including more than 200 quality checks to ensure it can run in extreme conditions. They cover harsh variables like Arctic wilderness and desert dust storms, including tests for temperature, pressure, humidity, vibration, and more.

Sustainably designed & packaged
By 2025, Lenovo is committed to obtaining 90% of our global operations electricity from renewable sources, removing one-million tons of greenhouse gas emissions from our supply chain. It’s why this all-in-one PC, for instance, comes with 90% sustainable packaging and comprises recycled materials. And why it also meets global standards for energy-efficiency and health & safety.
