Thank you! I used the DSDT you provided but i'm still unable to mute the audio or adjust the levels. I can use the keyboard function key to attempt to mute audio, and it displays the line through the speaker symbol on screen, but it still plays audio at 100%. Adjusting the audio with the slider in the OS X menubar has no effect on anything. To what extent must I have graphics working in order to get sleep to work? I now have CI enabled, but I've yet to get QE.

So, there is no need for a custom/hacked AppleIntelHDGraphicsFB.kext?

Dear Friends, The following is my hardware: HP Probook 4320t Notebook Intel Celeron Processor P4500 “Arrandale” (1.86 GHz, 2 MB L3 cache) Intel HM57 Chipset Intel GMA HD Graphics "Ironlake" 1366x768 32-bit @59 Hz Display Audio - I have sound with VoodooHDA, but I cannot control audio level and I cannot mute Sleep - doesn't seem to work at all Display Brightness - can't adjust at all Power Management seems to be an issue as well. I get very poor battery performance. I have deleted NullCPUPowerManagement.kext and installed FakeSMC 4.3.25 with Hardware Monitor app. i have also installed a hacked AppleACPIPlatform.kext and VoodooBattery as well as SleepEnabler.kext. HWMonitor shows CPU temps and "CPU Package" consistently at around 900 MHz. Battery % monitoring works. As stated above, sleep doesn't seem to work. I am also attempting to get CI/QC working for my graphics card based on the promising but *very* recent work being done here for Intel HD graphics. It is suggested that the DSDT should not have a DSM method in the GFX0 (or VID) section. I have native resolution and few glitches at the moment, so the computer is useable, but the lack of hardware acceleration makes some UI features slow. Overall, though, CI/QC is not a priority. Any help would be appreciated. Thanks! Send me erepere.zip
