What to do if a Lenovo ThinkServer RD240 does not turn off?
- Ccarrie21Sep 2, 2025
If the Lenovo Server is not turning off, determine if you are using an Advanced Configuration and Power Interface (ACPI) or a non-ACPI operating system. If using a non-ACPI system: 1. Press Ctrl+Alt+Delete. 2. Turn off the server by pressing the power-control button for 5 seconds. 3. Restart the server. If the server fails POST or you are using an ACPI-aware operating system, suspect the system board.
