回覆: [x86-power-control]: press the power button for a long time that can't force turn off system power

[Chris Chen (TPI)]

Hi Jason,

Thanks for your prompt reply.

The system stays on, because I can hear the fan in PSU is still running and CPU heatsink is hot, besides, the log would show "Graceful power-off timer completed" and "Host0: Moving to "On" state" after 5 minutes. Here are all logs of the power-control for your reference. Hope this can provide more details.

Hi Chris,

Holding the power button should force a hardware shutdown.  The BMC only
monitors this flow and doesn't participate.

Did your system shut down correctly and you just not see the logs in
BMC?  Or, did the system stay on?

Thanks,
