Probook 4540s Turbo boost not working


7 posts in this topic

Recommended Posts

Hi,

 

I have Probook 4540s without dGPU and CPU Power Management is driving me insane. When I inject AppleIntelCPUPowermanagement kexts, system boots properly and Turbo Boost is active for about 30 seconds. That's followed by instant reboot. I managed to stop the reboot process by adding debug statement to boot-args, but now the screen freezes instead of going into reboot. In System Logs (checked with Hackintool) I can't see nothing specific to that timing.

 

Does anyone have any idea? Or guide me how to check the logs properly? Or how to actually see the exception created on freeze?

 

Thanks!

Ok. Now that I'm all set maybe it's good to remind people about the original ask:

You should check the system logs

Use the Console app (Applications > Utilities > Console) to check logs during boot and after the freeze. Look for entries around the time of the freeze or reboot.
Ensure you have the latest version and check the "Logs" section for any clues.

I did check the kernel logs (collected by Hackintool) but it seems that even the logging stops exactly on the freeze. I can attach then here if someone is willing to take a look.

 

However, from reading so far, it seems that I might need AppleIntelCPUPowerManagement.kext(s) from Monterey (version 12.6 at least or something like that) but the only kexts I have are Vanilla kexts from OCLP github. Can someone please attach the right ones?

 

Thanks!
