[Guide] Native Power Management for Laptops

[RehabMan]

Good Evening sir @RehabMan. Here's my IOReg and Patchmatic files.

Looks correct.

Looks correct.

Hmm, that's a relief then. But do you know why my battery drops when I do a restart? And by the way, is my AMD Radeon graphics completely shutoff?

Battery status has nothing to do with power management: http://www.tonymacx86.com/yosemite-...de-how-patch-dsdt-working-battery-status.html

And by the way, is my AMD Radeon graphics completely shutoff?

It is not showing on the PCIe bus in ioreg.

I'm using a SMBIOS (Macbook Pro 9,2) corresponding my laptop specification (Ivy Bridge). I generated the SSDT following the steps from: https://github.com/Piker-Alpha/ssdtPRGen.sh
After I placed the generated SSDT to Extra folder, at boot I get this panic:

If I choose another SMBIOS; for example Macbook Pro 8,1 (for Sandy Bridge), the computer boots correctly.

DropSSDT=Yes

DropSSDT=Yes

I already set it. No change.

Re-download Yosemite from Mac App Store. Fresh install.

Make sure you set correct SMBIOS and reboot before using ssdtPRgen.sh.

I installed it yesterday. And I made sure to select an appropriate SMBIOS before rebooting; if I select a SMBIOS that doesn't correspond to Ivy Bridge I can't even generate the SSDT with ssdtPRgen.sh

Your SMBIOS must be in place and active prior to running ssdtPRgen.sh. Eg. you must install SMBIOS, then reboot, then generate SSDT.

Make sure you have Generate C/P States=No.

Make sure you obtained your copy of Yosemite from the Mac App Store.

Consider using Clover and perhaps -xcpm.

I followed this steps carefully.

Can't this bootflag be used in Chimera?
