Touchpad issue #1
Comments
Update the Bios, put the EFI debug in a USB and start at the end of the procedure if you start normally you will find in EFI USB some extracted files attach them here + ioreg and let's see what you can do. |
I don't have windows installed. And Bios is already upgraded. Maybe that is the problem, the trackpad model. I will look for it and take a look at this ACPI too. |

from this EFI there is not touchpad and keyboard. Changing the ACPI, the notebook freezes, but it is saying my touchpad is ELAN0504 OC0.7.3 => here keyboard is working, no touchpad. |
ioreg OC 0.7.6 describe the precise specifications of your laptop even if it has a discrete GPU as well as integrated ACPI.zip |

This EFI works well, keyboard is working but touch not yet. Checking an EFI from another laptop I found this: Known Issues
Could this be the same problem? |
of the efi I pass you I need ioreg, otherwise I'm in the dark |

Keyboard not working yet. |
I have the same results here. |
Try this, I extracted the kext keyboard from VoodooPS2.kext let me know if it works. |
I had tried a new installation of Big Sur and still the same issue. Really strange because it works well there for you. But thanks for all your effort |
Try replacing VoodooPS2Controller.Kext 2.2.7 with earlier versions, such as 2.2.6 or even earlier |
It doesn't work yet. I had tried the same thing with VoodooI2c and VoodooPS2 from OC0.7.3 but nothing has changed... Thank you for your help |
