So, I've gotten 10.7.1 running on my laptop. I could say 95% of it is working. My VGA port is not working, the battery life is meh even with Native SpeedStep working, and the audio through HDMI isn't working. I have a ALC272 on this laptop running with Voodoo HDA, but I would prefer if I can get it working without it.

Many of the fixes that I've see that might work use DSDT and I no nothing. I've tried following tutorials but that isn't working... anyone want to help me with this daunting task?

VGA will not work without a Framebuffer edit. If you extract your IOreg and DSDT and post them here I will take a look.

Here are the files that you requested. Keep in mind I have QE/CI with FullRes enabled using native Lion Drivers with GraphicsEnabler=Yes, and AtiConfig=Orangutan. The HDMI works without sound, but the VGA does not.

DSDT: https://www.dropbox....acq9tl/dsdt.dsl

IOREG: https://www.dropbox....mousginni.ioreg

I tried attaching them as attachment but for some reason it wouldn't let me so I used dropbox instead.

Attached is a new DSDT. Install in your Extra folder and then restart. Also attached is a working AppleHDA for ALC272 which should enable onboard audio.

I also injected your GPU into the DSDT so you should no longer need GraphicsEnabler=Yes

Post a new IOreg after restart.

Hey I tried your new DSDT and the driver for ALC272 and the VGA port worked with the new DSDT. I'm having trouble using it though as if I turn on mirroring the screen on the external gets distorted and without mirroring it works fine. I also need to add a higher resolution as all the resolutions listed are not the full resolution of my monitor. The modified ALC272 kext on the other hand did not work. I used kextstat to see if the kext was loaded and it wasn't loaded so maybe I need to add my device IDs or something. I will send you the new IOreg. Also would it be possible for you to send me the modifications you made in the DSDT as I have another DSDT with the VGA not working but it has shutdown and restart working perfectly so hopefully I can combine them together or something.
