    IT has a new best friend

    The ThinkCentre M820z provides the security your IT team is looking for, safeguarding your enterprise data via embedded Trusted Platform Management (TPM) 2.0 data encryption, BIOS-based Smart USB protection, and an intrusion switch that sends alerts if someone attempts to open the chassis. It’s also quick and easy to deploy, with a conveniently small footprint.

    Unmatched productivity

    With its PCIe SSD powered by 3D NAND technology and optional Intel® Optane™ Memory, the ThinkCentre M820z promises responsive computing and seamless multitasking. We’ve engineered this all-in-one PC with productivity-boosting features like USB 3.1 Gen 2** and USB-C ports for faster data transfers, so you can keep your business moving.

    Maximum protection

    The ThinkCentre M820z AIO’s integrated Trusted Platform Module (TPM) 2.0 firmware encrypts your data and passwords. Its BIOS-based Smart USB Protection lets you further protect your data—simply configure the USB ports to respond only to specific devices, preventing unauthorized copying of files. With the optional Fingerprint Reader Mouse, add another level of biometric security when you log in with Windows Hello.

    Easy to set up…

    This compact AIO takes up hardly any space, keeping your desk space tidy and professional. It’s also VESA-mountable, and the borderless display and monitor stand make it even less intrusive on your workspace.

    …and easy to use

    Little features make the ThinkCentre M820z convenient and manageable. With the Keyboard Power On feature, you can boot up your system from the keyboard. The Smart Webcam rotates 180 degrees horizontally and 50 degrees vertically, enabling you to switch between front and rear cameras, making video conferences a snap. This PC also comes with ThinkShutter — a physical cover you can toggle on and off to protect your privacy when the camera is not in use.

    Steadfast reliability

    Tested to meet military specifications, the ThinkCentre M820z is durable enough to last. It’s tested against eight MIL-SPEC standards: low pressure (altitude); vibration; high temperature; low temperature; sand/dust; temperature shock; humidity; and shock. In other words, you can depend on this AIO.

    Also protects eyes

    The ThinkCentre M820z display helps reduce eye strain; its antiglare panel scatters light and stays flicker-free, and its Eye Comfort and Low Blue Light certifications ensure your eyes will stay comfortable when working those long hours.
