No news on the schedule, but with 9.1 Beta, the code has finally been fixed to deal with several issues and the correct answer is: performance_cx_lowest="Cmax" economy_cx_lowest="Cmax" And, no, I don't recall where it is documented, only that I could not find it and the Andriy, the developer, told me in response to my query on acpi@. I can tell you that it works correctly on my ThinkPad T520. -- R. Kevin Oberman, Network Engineer E-mail: kob6558@gmail.com
