HP Probook 650 G5 Ventura Opencore v1

Hello,

 

I am currently using a HP Probook 650 G5 with Ventura and Opencore V1

 

This device is running a i5-8265U cpu. I am currently encountering 2 remaining issue with this one and hope someone in the forum can help me.

 

First is the trackpad (I think it's a Synaptics one with L2C connection), it is working and do appears in the Mac OS settings but the performance of it are very bad, it is very slow and sometimes I am loosing the tracking of the curso. I think there is something wrong with my choice of kext or acpi patches.

 

The second issue is during every boot, I am getting the HP message saying that my system clock is not correct. I thought that SSDT AWAC would fix this but I am still getting the message at every boot. 

 

Could  someone please help me with the remaining issue?HP 650 G5 Ventura.ioreg

 

Thanks in advance for your help.

Ok so I finally fixed the BIOS clock error at boot (had to change RTCchecksum setting to "false" in OC config.plist)

 

Everything is now working on this laptop but the touchpad is really jerky and super slow, laggy. On my previous HP Laptop (X360 1030 G2) the trackpad was working beautifully (better than in Windows!) but this one was an ELAN

I finally seems to fix all of my issue including the touchpad. I share here my EFI and DSDT dump to help others.

 

It seems that the device is working well but I have the feeling that this could be better. So if someone would like to check my EFI and correct things, you are welcome. The zip file contains my EFI, DSDTT dump and also Jorge extract .

 

Thanks in advance for your help.

My EFI was made after original ACPI study extracted from your Bios. On the left of the image of the Ioreg file is mine, on the right is ioreg of your efi. As you can see, drivers are missing.

In your I2C1 you need USTP=One the solution

That's where I found the solution in DSDT

If you carefully compare Ioreg of the 2 EFIs you will find the reason for the improvement you found.
