Once I do force poweroff then only I am able to send any command to ME. I don't know what is the relation of power to ME access on i2c bus.
I have been told that this is not expected behavior and that you can 
file an IPS ticket for support.

The biggest issue with force poweroff using the power button while the 
system is off is that it will first start booting the system then 
immediately shut it down which is not desired behavior.

What happens if you try to power on in the failure?  Will it go to the 
On state where you can issue a ForceOff?

Thanks,
