USB map - fix #4

Closed topiga closed 3 years ago

topiga commented 3 years ago

Hi, I was curious as my power consumption is higher than I thought it would be, did you make an USB fix/USB map like in dortania's guide ? I experience some issue with "uia_exclude=HS07" that doesn't work. Do I need to add ";" after it ?

  1. I haven' t made a USB map.... it was not needed. Of course you can make one just to disable the fingerprint scanner.
  2. I also have seen that uia_exclude=HS07 seems to not work any more.
  3. ";" is not really necessary, unless there are more ports to disable.
  4. Power consumption is higher than expected due to touchpad working in polling mode. That results to much higher cpu usage in idle and when using touchpad.

Comparing to my older thinkpad t460 with DDR3, the cpu utilization of the Ideapad at idle is 400% more and power consumption at idle is 0,60 watts more.

The biggest bet is making touchpad work reliably in GPIO pinning mode. The closest is the the SSDT-TPAD-Air14IML.aml.... but alas it s practically unusable. It work s in pinning but its choppy and uses even more power.

Okay so I'm going to see if with a USB map, less power is used, and I'm going to try pinning mode with SSDT-I2C-SPEED (Maybe it is the solution ?).

Do you know some tools to see power usage of each component in macOS ?

  1. You can try... but it is probably a faulty ACPI implementation of our laptops .. .many have tried... all have failed up to today.
  2. Saddly no. I only use Intel Power Gadget, coconut battery and IOReg exlorer

Okay. Can you tell me all the changes you made to add the trackpad support please ? (to not mix polling and pinning patches)

Hasodikis commented 3 years ago

In the EFI of the release its the SSDT-XOSI and the relevant patches of the config.plist (i think) .. I am at the office now and dont have the laptop with me.

We have lost numerous hours trying to pin the touchpad. I think that marianopela will be of more assistance to you on this matter. I have given up with it.

Its one of the reasons that I stopped using the Ideapad as my road everyday laptop .... and hackintoshed the older T460
