ruorbe Posted June 14, 2013 Share Posted June 14, 2013 I've made my own DSDT and I got almost everything working smoothly Shutdown, sleep, audio, etc. but I cannnot get speedstep working I only get 2 steps. I've tried ssdt, generate P and c states and both without any luck. I'd really appreciate your advice. Thanks.
