Have you try ACPIBatteryManager.kext? What do you have for battery kext?

http://www.hackintoshosx.com/files/file/316-lapic-kernel-patcher-v07/ for sound, you can change the setting in info.plist of voodoohda example VoodooHDAEnableHalfMicVolumeFix VoodooHDAEnableHalfVolumeFix VoodooHDAEnableMuteFix VoodooHDAEnableVolumeChangeFix DSDT HP Pavilion.aml 2.zip

Your wireless card is not supported. MyHack is not Yosemite ready but there are plenty of guide here you can find that will. Use our search option. Attached is for the LAN RealtekRTL8100.kext.zip

Here DSDT HP Pavilion.aml.zip

See here.

check here if sandflee's file are not working for you

Wern has a working DSDT for Nvs4200m that has sleep working here http://www.insanelymac.com/forum/files/file/342-latitude-e6420-nvs-4200-dsdtaml/

Did you use myHack to build your system? If so, run myHack/myfix (quick).

Please include your system specs CPU GPU resolution? Try booting with -f -v and post the error or where it hangs.

Try this one, remove EAPDfix

Here, try this patched AppleHDA. Remove AppleHDAALC and the 3 patches in config.plist. Install to S/L/E with any kext utility. Make a backup of the vanilla AppleHDA. Repair permission and rebuild cache. AppleHDA.kext.zip

i3-???? Please be more specific

in your installer? here AppleHDA.kext.zip

You need : vanilla version of AppleHDA.kext (un patched) restore to S/L/E dummy AppleHDAALC.kext I posted in the link install to S/L/E the 3 patches in Clover config (in guide) Audio layout-id of 1 in DSDT (in guide)

Did you try this version of AppleHDAALC?

Thanks for chiming in LexHimself, but that's for HD 4000, not HD 3000.

Don't forget step #8 of Post Installation 8. Tuned up your system

Download the bootpack, update some files from the update section if you're building from 10.10.2. Remove the 2 FB and keep only the one from 10.10.2 update. If you encounter KP, most like you have NullCPUPowerManagement.kext renamed to NullCPUPowerManagement.kext.bak. Please post your KP.

Download is fine. Re-try the download.

Check /Extra/Extensions and /System/Library/Extensions to see if you have both install or run kextstat | grep PS2

One or the other, not both. With Voodoops2controller from my bootpack, you'll be able to scroll with your touchpad and trackstick. ApplePS2Controller will only act as a regular mouse. To drag and drop, make sure to enable Clicking in Trackpad preference.

Restored AppleACPIPlatform.kext with 10.10.2 unpatched. Issue is fixed.

You didn't install the updated 10.10.2 files. AppleHDAController (266.5) is 10.10.1 file Download the updated files and install to /S/L/E

run from terminal and post output kextstat | grep AppleHDA kextstat | grep voodoo
