It is not appropriate to hijack threads unrelated to your own issue/hardware.

Made those changes using Clover Configurator, just to be sure.

Updated IOREG file is attached.

Has that helped in any way? The battery drain is/was horrible.

The extra SSDTs are gone (you can check your self by looking at AppleACPIPlatformExpert -> ACPI Tables.

Have you tested your pstates with DPCIManager?

*Update - since I implemented those changes my speed stepping seems fairly limited and stuck between two states.

Or is that how it's supposed to work?

Apologies, it's an i7 3632qm. Core clock of 2200MHz and a multiplier of 22 I think.

I had an inkling that something related is affecting my battery life.

I'll update my profile when I'm not on my mobile.

Your profile lists HD4000/HD7950 as graphics. Is that true? You have both on this laptop? Do you have the Radeon disabled in BIOS? If you don't, it will eat battery.

The 7950 is in my desktop hackintosh build. There's an nvidia gt635 in the lenovo laptop but it's disabled in BIOS.

As an aside for anyone attempting to implement sleep - the kp I received was related to

"unable to find a driver for this platform: ACPI [blah-blah] in IOPlatformExpert.cpp:1504"

It's a clover issue I imagine

Probably Clover auto-patching for DSDT. Best to avoid that feature and patch the DSDT the old fashioned way...

Yes, just realised that there is auto patching in the Clover config provided by Ppogorze for ALC269 audio. Will try manual edits tomorrow and post results.

Does that speed stepping seem ok btw?

A bit surprised there isn't levels between idle and nominal (22), but...
