How to install Lenovo ThinkCentre M820z

• Unbox the ThinkCentre M820z and place it on a stable desk in the desired workspace. Ensure there is adequate clearance for ventilation and access to the rear ports.

• Power on the system and follow the on-screen prompts to complete the initial Windows setup or the configured operating system installed by your IT team. Connect to your network (wired or wireless) and verify basic connectivity.
• Run essential updates to the operating system, drivers, and firmware. Use Lenovo Vantage or Lenovo System Update to obtain the latest security patches and performance improvements for the M820z.
• Configure security features and user access: enable TPM 2.0 if not already active, set up secure boot, and establish user accounts with appropriate permissions. IT teams may also deploy corporate security policies and tools via centralized management consoles.
• Calibrate display and peripherals: adjust brightness and color settings for your environment, connect printers or displays as required, and verify video and USB peripherals function correctly.
• Consider IT deployment options: if your organization uses centralized imaging or asset management, prepare the M820z for bulk deployment and policy enforcement. For shared workspaces, set up power on delay, privacy settings, and accessibility options as needed.
• Optional enhancements: if you anticipate growth, inquire about memory or storage upgrade paths supported by your specific configuration, and plan cable management or VESA mounting if your workspace requires a wall- or arm-mounted solution.
