As part of our ThinkShield security solutions, we offer a combination of hardware and software that work together to keep your system and your data safe. The ThinkCentre M90a all-in-one boasts smart USB ports to prevent unauthorized people from uploading files, while a chassis intrusion switch detects any attempts to remove the system cover. Trusted Platform Monitor encrypts your data and your passwords. And biometrics let you use your face to log in with the optional hybrid IR camera.

The optional PrivacyGuard display panel on the M90a features an electronic filter to keep your screen private—and it’s easily controlled with just the touch of a button. When on, if someone glances at your screen from an angle, the panel appears black. What’s more, the display automatically blurs when you look away, which further secures your critical data.

ThinkCentre PCs are tested against 10 military-grade requirements and more than 200 quality checks to ensure they run in extreme conditions. From the Arctic wilderness to desert dust storms, from temperature extremes to vibrations and shocks, you can trust your ThinkCentre M90a all-in-one will handle whatever life throws its way.

With our next-gen Intelligent Cooling Engine (ICE) 4.0, the M90a delivers unparalleled efficiency using three different modes. Best Performance (BP) Mode provides a 15% power increase to your system. BE Mode provides a quieter experience, running 3 decibels lower than BP Mode. Full Speed Mode provides maximum cooling to prevent your system from running hot.
