Premium performance.
Optimized for large enterprises, these are the first ThinkCentre desktops to include 2nd generation Intel Core processors, with Hyper-Threading and Turbo Boost technology for more powerful performance and faster multitasking. Transfer data in a flash with SATA III hard disk drives — rated at 6GB per second (twice as fast as SATA II). Maximize productivity with their support of up to four independent displays in discrete graphics mode. Lenovo Enhanced Experience 2.0 for Windows 7 with optional RapidDrive lets you start your PC faster and open applications more quickly. And the Secure Managed Client 2.0 solution can help your enterprise reduce IT costs with the potential to save up to 40 percent over three years as compared to a managed PC environment, and up to 63 percent in total cost of ownership as compared to a virtual desktop implementation.

Best-in-class manageability.
You'll appreciate how easy it is to manage these desktops, starting from the moment you order them. They're configure-to-order, customizeable and scalable, with plenty of options for your enterprise's specific needs. They're available in three form factors: Tower (25L), Small (11L) and Eco Ultra-Small (4.5L). Intel vPro with Intel Active Management Technology (AMT) allows your IT personnel to access, diagnose, repair, manage and secure the desktops from remote locations, saving time and reducing maintenance costs. Intel Stable Image Platform Program (SIPP) enables smooth transition to new technology generations by aligning and stabilizing platform components, enhancing software stability and reducing the need for driver changes. Even hands-on maintenance is a snap, thanks to the easy access to our tool-less chassis.

Tight security.
Keep your investments safe and clean with some of the industry's best security features. Lenovo’s Hardware Password Manager enables remote and central management of keys and passwords for self-encrypting hard disk drives. An embedded Trusted Platform Module (TPM) chip protects your data while allowing you to manage encryption keys and processes. The option to disable individual USBs allows you further security. And on the small form factor machine, RAID with ODD support gives you the peace of mind of secure data and an added backup mechanism.

Environmental responsibility.
The M91/M91p are our most eco-friendly, power-saving business desktops, thanks to features such as the ENERGY STAR-compliant power supply unit and the latest Lenovo Power Manager tool. These desktops will use energy more efficiently and give you increased power savings over a three-year life cycle. They use up to 42-percent post-consumer content, bolstering your company's commitment to the environment. Not to mention your employees' physical environment, which benefits from ergonomic design features like easy expansion of system components, a top handle for easier mobility and front I/O ports and a top power button for easy access.
