At least wanted to answer more quickly ... Yes exactly, this was my idea. Have all the tools from earlier experiments. (HDX fan control) Unfortunately it is not so simple and yet determined I need ideas for a meaningful "DSDT Mod". All that from next week. I'm glad you're still in the boat. And just to clarify, all the tools and the foundation of my ideas based on your postings. That's what we have at the same time, the same ideas. Thank you very much. You have but to me a decisive advantage, you mastered English.
