10.9 on ThinkPad Edge E320 | Power Management, Overheating, Battery Life Issues | Please Help

Hi all.
I just got into the Hackintosh scene a couple of weeks ago, and got 2 Hackintosh builds up and running from doing a lot of reading on tonymacx86Reddit/r/Hackintosh,OSXLatitudeInsanelyMac
I got a Desktop configured, which was relatively easy compared to getting OSX running on my ThinkPad E320.

What’s working so far

I got almost every little frigging thing working on the ThinkPad E320 (minus the Wifi, which is a very typical Laptop woe I’ve found. I’ve resorted to a nano USB wifi adapter while a Broadcom chip ships).
 

  • CPU
  • GPU
  • Webcam
  • Intel HDA
  • Keyboard/Trackpad
  • Ethernet
  • USB Wi Fi
  • Bluetooth
  • Internal Display, HDMI out, VGA out


So what’s wrong?

The only problem is that the laptop overheats
I do not know what exactly is wrong, but I think the fans are simply not spinning fast enough. I used to run Linux and Windows on this very laptop before, and the fans would spin up significantly every time the processor load would increase.
After I Hackintoshed it, the fans can barely be heard even when the CPU temp goes up to 80-90 degrees celsius! And even though my CPU is detected (with 25 P-States) the battery life is really really bad. I get roughly 2 hours on a full 100% charge on a 6 Cell Battery.
I tried patching my DSDT and a little bit, but mostly it’s the same from another DSDT I found for my motherboard and model - its the Intel HM65 Chipset. The DSDT worked well, and I had to make a slight tweak for getting the Intel HDA. I used Piker-Alpha’s ssdtgen script to create the SSDTs for my machine and everything boots up and gets detected like I said.


What I’ve tried so far / more information for diagnosis

1. Underclocking with SSDT/DSDT - Fail

I’ve tried solving the overheating/battery life issues by forcing an under clock. I entered lower values into Piker’s script to do this (the script generates SSDTs without any errors when I put in lower Base Frequency and Turbo Frequency and TDP values) but the SSDTs cause the infamous error-

P-Step Stepper Error 18 at step 35 Error.

I think the newer SSDTS should work, but I think my DSDT is referencing the old SSDT with 25 P-States or something like that, and that’s causing the P-Step error on boot (this is just my hypothesis, I’m entirely unsure). I have included my working DSDT and SSDT in the post here so the community can have a look and help patch these files to underclock my processor to 1.8 Ghz with 2.2 Turbo (think that would be easier on the overheating/battery drain).

2. Underclocking with Clover - Fail again

My second approach to under clock was to edit the CloverCPU configuration portion. I entered lower Frequency and Bus Speed and 0x00FA Latency values (according to Clover Wiki that Latency is best for Notebooks). But I saw no difference, and this experimentation failed as well. :(


Some other weird things

Looking at HWSensors app and Intel Power Gadget I can see the CPU stepping working (variation in the frequency curve) but I definitely don’t see 25 steppings (as the chart’s jumps are not that granular) which Piker’s script outputs for my current (working, stock clocked, linked in post) SSDTs. DPCI Manager shows around 6 P-States in fact. 

AppleIntelCPUPowerManangementInfo.kext by Rehabmanshows around 25 P-States, but then again the kext only outputs those messages during boot. Could it be that during boot 25 P-States are detected initially and as the kernel loads it’s lost for some conflict? 

HWSensors also does not have a Fan control portion either (are my fans not being detected at all?). So I can’t manually control my Fans either. :(
 

Please help. I would ideally like my CPU under clocked and my fans working properly. This is the only step left for my beloved HackBook. Could the USB wifi adapter be screwing things up? The laptop goes into sleep, deep sleep and wakes up fine. I spent a lot of time getting it to this far, just need help with the power management/fan control portion, so please help if possible.

I’m attaching some files so that maybe you guys could take a look and help diagnose the issue -
[1] My Clover Config 
[2] DSDT/SSDT 
[3] IOReg 
[4] AppleIntelCPUPowerManagementInfo.kext output (I installed the kext and it only shows the output in the boot log :/ ) 
[5] KextStat dump

Laptop Detailed Specs

LENOVO ThinkPad Edge E320 
Model - 1298CTO 
Mobo - Intel Express HM65 Chipset 
CPU - Core i5 2520M (Sandy) (2.5 Ghz to 3.2 Turbo) 
GPU - Intel HD 3000 (650 Mhz can go upto 1.3 Ghz [not sure]) 
RAM - 2x 4 GB Corsair SO-DIMM 1333MHz 
Storage - SanDisk 128GB SSD


Any help at all will be greatly appreciated.

Thank you.

SSDT won't help you here (other than for PM, which is only prevents further heat output, but won't fix fan control). Due to the fact that many of them are black boxes and OEM-specific, no laptop's Embedded Controller is supported by LPCSensors (in HWSensors), so you'll need to find the proper registers in ACPI. You need to do (fairly complicated) DSDT edits (finding the registers yourself) to enable fan control using ACPISensors. Actually, you might only need to use an OS Check Fix to mask Darwin as Windows in order to make the fans to behave how they do in Windows.

      A big thanks to wegface for teaching me a lot of things.
       
       
      Tested on Catalina 10.15.4 and Clover EFI 5104 (Catalina Patcher)
       
      Not Working:
      - realtek sd card reader (pm me if you have a fix)
       
      Notes:
      **CPU patches are disabled, if you are using a locked BIOS you must enable them**
       
      Clover EFI:
      - Install it in UEFI Mode and change your hdd partition table to GPT.
      - You will be able to install ANY OS in EFI mode, even if this pc does not support EFI at all! (No guide available for this)
       
      You will need:
      My unlocked BIOS (OPTIONAL) (here) Latest Clover config from CCE Bank (here) (asus k53sj-kylon) Rehabman Voodoo PS2 Controller (here) acidanthera AppleALC (here) acidanthera Lilu (here) acidanthera VirtualSMC (here) acidanthera SMCBatteryManager (here) acidanthera SMCLightSensor (here) acidanthera WhateverGreen (here) Mieze Realtek RTL8111 (here)

      Opencore is running really really slow on Catalina 10.15.4. So It was running perfectly before I put the ssdt-pnlf for enabling Brightness control. it is running really slow and I verified my config with the sanity checker and its all correct. can someone please help. I am attaching my oc folder.
