metacollin Posted January 15, 2012 Share Posted January 15, 2012 (edited) So I have a Dell E5420 and successfully installed Lion. I can tell the DSDT needs some work. I already applied all the changes I could diagnose, but there are still some major issues. It also doesn't help that Dell uses atypical names for lots of stuff. The hardware is pretty typical of a sandy bridge laptop: hm65 chipset, HD3000 graphics, i7 2620m CPU, HD+ display, and no web cam or biometric sensor. My vanilla DSDT is attached, see below for the edit. e5420vanilla.zip Edited January 23, 2012 by Guest Quote Link to comment Share on other sites More sharing options...
metacollin Posted January 23, 2012 Author Share Posted January 23, 2012 I am stuck no longer! I *think* I caught everything, I've gone through the interesting parts of it line by line. It certainly seems to be running like a champ, I am working on getting sleep and speedstep running. I am not using NULLCpupowermonitor.kext and generating C/P states, I am not sure if anything interesting is happening yet. Here is the (tentative) final DSDT edit for an E5420 with an HD+ display, no discrete GPU, webcam, or biometric sensor. I am working in winmerge to organize my changes into a universal patch for all e5420 configurations without a discreet GPU.
