hi Sniki thanks for the help.

I have updated my profile spec. Audio seems to not work even after installing
  • ALC292
  • CodecCommander
using kext wizard and applied the alc_fix . Any solution?

managed to fix the audio problem.

The problem is that i copied patched folder (from efi config, ssd, themes zip file) into efi/clover instead of efi/clover/acpi.

One more question. I see that SDT (CPU Power Management SSDT) is already provided in the patched folder. Do i still have to run the following step?

Power Management

for Power Management you have to create a SSDT from PikerAlpha`s script.
Please follow the Rehabman Guide for the Instructions:

No idea what you're referring to (you didn't attach complete "Problem Reporting" files).
But your ioreg in post #82 shows CPU PM not implemented.

hi Rehabman. sorry for being an complete idiot. i re-run the ioreg and uploaded the clover files. Can you guide me in solving the native power management?

This ioreg shows CPU PM implemented (via SSDT.aml in ACPI/patched).

oh. so it's safe to say cpu pm is implemented? Battery seems to be depleting fast though

Yes.

Battery seems to be depleting fast though
May be other factors:
- unsupported PCIe devices without drivers (therefore not running in a low power state). I think I see unsupported WiFi and a card reader
- serial port enabled, but probably not needed
- brightness set high
- USB not implemented correctly (for example, you have EHCI controllers enabled, although they seem to be unused)
- could be background processes using CPU resources (check Activity Monitor)
- USB WiFi tends to not be power efficient
- FakeSMC sensors are not efficient
- Google Chrome is hooking your USB ports (see FAQ)
