Quick Overview
Intel Pentium Gold G5400 (2C, 3.7GHz, 4MB), 4GBx1, 500GB 7200rpm 2.5", 21.5" FHD (1920x1080) WVA Anti-glare, Intel UHD Graphics 610, DVD±RW, Intel 8265 ac, 2x2 + BT4.2, Windows 10 Pro 64
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 Intel® Optane™ Memory, the M820z promises responsive computing and seamless multitasking. And its USB 3.1 Gen 2 and USB-C ports enable fast data transfers, to keep your productivity high.
Maximum protection
The M820z AIO’s integrated firmware, Trusted Platform Module (TPM) 2.0, 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. An intrusion switch deters unapproved physical access. And with the optional Fingerprint Reader Mouse, you can log in with Windows Hello.
Easy to set up…
This compact AIO takes up hardly any space, keeping your desk space tidy and professional looking. It’s also VESA-mountable, and its borderless display and optional stand make it even less intrusive on your workspace.
…and easy to use
Little features make the M820z convenient and manageable. With the Keyboard Power On feature, you can switch on the AIO from the keyboard. The Smart Webcam rotates 180 degrees horizontally and 50 degrees vertically, enabling you to switch between front and rear cameras, while making video conferences a snap. It also comes with ThinkShutter, protecting your privacy when the camera is not in use.
Steadfast reliability
Tested to meet military specifications, the 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. You can depend on this AIO.
Also protects eyes
The 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.
