(Acer Aspire 5740-6378) Need a DSDT that works to enable sleep mode! ;(

Hey guys!

 

So I successfully installed MacOS 10.8.3 on my Acer Aspire 5740-6378. I also have successfully installed the Intel HD Graphics kexts (QE and CI for 10.8.3). I found a working kext to make the touchpad fully functional and another working text to have a working battery status indicator. My only real issue is sleep mode. I can't get it work no matter how hard I try.

 

I've tried:

 

1) SleepEnabler and removing nullcpupowermanagement.kext

Result: Sleep Mode = black screen and then fan buzz, while computer never completely turns "off"

 

2) Extracting and patching my DSDT with the "Aspire 5740" DSDT from olarila.

Result: Can't boot into MacOS

 

When I tried rebuilding my DSDT (using DSDT Editor) and fixing for errors - I got 4 warnings that I couldn't "fix". When attempting to use the DSDT (putting it in the Extras folder), I kept getting kernel panics when trying to boot into MacOS. I then had to remove the DSDT to get back into MacOS (I am not using a DSDT at the moment!).

 

3) Using no DSDT with nullcpupowermanagement.kext (currently what I am doing now)

Same result as #1

 

I have made a backup of my DSDT (unpatched) using this perl code via terminal:

dsdt-original.aml.zip

 

And here is my patched DSDT that results in 4 warnings from the compiler and does not allow me to boot into MacOS:

DSDT-patched-4warnings.aml.zip

 

Please help me fix my DSDT, as I heard this might be the best way to fix the sleep mode issue! Also, does anybody know if I need an SSDT as well? I've never made one nor have any idea on how to make one for this laptop.

 

To conclude: The system is fully functional. I can reboot and shutdown with no problems, sound works, webcam works, graphics work with perfect resolution, speed is great, and bootup usually works without any kernel panics.
