I suppose you made some mismtakes:
I had in E/E:
What remained in E/E is (recalling my brain:
Concerning sound I have to fire up Windows with Aida64 to see what I have. I might be wrong with the sound as I just assumed it by reading reviews for the series. One review even states a Nvidia GT216 High Definition Audio Controller. I am confused and have to check.
I fired up the fixed DSDT yesterday and the lap started well. Speedstep and brightness works now. However I tested Sleep and strangely had trouble with wake. Have to investigate further.
- you don't need GraphicsEnabler=Yes key in Boot.plist if you're using gfx fix in DSDT
- do you really need JMicron36xSATA?
- EvOreboot, LegacyAppleRTC, NullCPUPowerManagement never were needed
Please attatch your latest: DSDT.dsl, smbios.plist, Boot.plist. Leave in /E/E only Fakesmc, ACPIPS2Nub, VoodooPS2, remove VoodooHDA and boot your lap without your custom DSDT ('DSDT=No' at boot or move it somewere out of the /Extra) and save once more IORegEpl and attach it also.
