I have laptop with probably broken BIOS. C1E is not enabled and with Linux I get poor batery life (1-1,5h). C1E is not enabled because content of MSRC001_0055 is 0. I could rewrite it, but I don't know IoAddres value. So request for anyone with working C1E on AMD laptop, could you provide your content of MSRC001_0055?

C1E may be not enabled because CLMC (centralized link management controller, part of HyperTransport) is enabled. How to check if it is enabled and how to do warm reset to deactivate it?
Both AMD and Acer support didn't want to help me.
