i added a few more fixes and some new lines, hopefully it will work now, your dsdt seems fine, first startup the system then shutdown after a few seconds, if it works, try to sleep once booted up, then check if your fans and lights turns off,, if you can wake from any state of sleep and sound works, you are on your way to native power management.
replace all the files with the edited ones
wow, that was some ride there...
I used the two files, then restarted, and then shut down.
Shutdown worked. And again. and again, and again. Wow, awesome!
Then i selected 'Sleep' from the menu bar, the machine switched off the monitors, and made a restart sound (fans revving up). Only it didn't do anything anymore. Forcing it off via the power button and then back on resulted in a continuous lights/lights off/lights/lights off/lights/lights off state, and it didn't get to the POST screen. The only thing that helped was resetting the CMOS. Thankfully, the BIOS was still intact, and defaults could be loaded. After Clover booted ElCap again, i noticed no Apple start logo and it went directly to the password screen.
So it's a failed attempt at a sleep state, i imagine.
No matter, i'll never use Sleep anyway. (only now it's a self destruct button)
I see you've checked a few of the 'new fixes' in addition to the old ones, i was trying my hand at the S3 Fix before you've posted the fixed files.
RazerX, try these:
Also the size of the dsdt is different, what did you change?
So summary; shutdown works, sleep self destructs, dsdt file got smaller.
