I have generated a ssdt according to the script of Pike R Alpha. I have also managed to create a dsdt with the help of someone else. I have used Chameleon. Enabled drop SSDT, disabled generating C and P states.
Everything except the trackpad is fine even powermanagement (sleepmode) until I touch the trackpad. Then - although the trackpad does not function - the keyboard gets blocked. I have to reboot.
Now here is an even more strange thing. If I use a dsdt I have extracted on this laptop (but not patched at all) then everything is fine including the trackpad but power management is not there of course. Even if I remove the VoodooPS2Trackpad.kext, the trackpad keeps on working. In fact I have removed all things I could find relating to the trackpad, but that does not bother the trackpad. It keeps on going.
So now here are my questions:
- How can it be that the trackpad keeps on running if I cannot find a kext/driver referring to the trackpad?
- What is wrong with the dsdt file? If I use it the trackpad will not work but touching it only once will block the keyboard until reboot (IRQ conflict?)
I have attached the dsdt file which causes the trackpad to malfunction and also ssdt.aml and org.chameleon.Boot.plist.
Uhm...: Forgot to tell you that the trackpad pane in system preferences tells me: " Trackpad not found" ...
DSDT blocks keyboard

Hi,
I have recently installed Yosemite on my Medion Akoya E6221 laptop.
Spec: i3- 2310M (2330M?) processor, Sandy Bridge, Intel 6 series/C200 chipset.
