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 major 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:
Attached File  dsdt-original.aml.zip   19.42KB   5 downloads

And here is my patched DSDT that results in 4 warnings from the compiler and does not allow me to boot into MacOS:
Attached File  DSDT-patched-4warnings.aml.zip   19.84KB   4 downloads

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.

Finally, one other issue I have, which is minor, and that occasionally the Kernel panics (using no DSDT) during boot up and forces me to force shutdown and try to get into MacOS again, but it's random (doesn't always happen!). When I do get into MacOS (and I usually do with no DSDT), the system is fully functional. I am hoping that with a correct DSDT that this will also fix this issue as well.

Lastly, I can reboot and shutdown with no problems, sound works, webcam works, graphics work with perfect resolution, and speed is great.
