Trackpad suddenly stops working. Please help!

[David Tirddea]

@MaLd0n Hello. i am sorry to bother you again but my trackpad suddenly stopped working. while checking the ioreg it seems the i2c devices aren't getting fully recognized. Idk why. Maybe you can take a look please:) Thank you so much and sorry for bother. some infos that may help you I guess: apic id - TPD0, trackpad - syna2b52 which is i2c and smbus at the same time. thats how i remember from windows thoough. Thank you

Hi Mald0n. I kinda remade my EFI and added the DSDT you patched. Well, I dont know why but it's not working whatever I do. I did change the kext order in different ways, like google says and a lot more. What else can I do more?

Okay. I did some researches on my own but no luck. I tried your efi, trying to adapt it with your patched dsdt but no luck. I guess there's something in the DSDT which makes the i2c controllers to not be recognized also in ioreg and settings. the thing is, using my previous efi with ssdt and ssdt xosi + patch for it, it WORKS but badly if I don't use the command that forces polling mode! but breaks during sleep. while booting with your dsdt + no other ssdt + no patch for xosi, it doesn't work. Tho, it is not being recognized in the ioreg, neither in the settings. I am posting my previous EFI + my new EFI (the one which contains your patched dsdt) + ioreg when booting with my previous efi + ioreg when booting with my new efi. Maybe can I get some help, sir?

first of all, i'll be sending the dsdt you patched: https://we.tl/t-ttpOIbdoTV

i decided to send you the runme when using the old efi: https://we.tl/t-Cg2sp9gRnL

and about when using the old efi, it just makes the i2c controllers (there are 2), being recogznied as pci... something like that, and no, it doesn't work. I ll appreciate your help through this. Thank you

synaptics devices die after sleep if using voodooi2c

um yeah i knoow. should i try voodoormi instead? it is i2c and smbus trackpad from what i've seen from windows. Maybe using the smbus kext will make it work better than the i2c? the thing is isn't being recognized neither after sleep. Just if I using the ssdts i mentioned, it is working normally, but breaks during sleep which is normal. Should be there something I can do by myself? I have no idea at the moment,

[MaLd0n]

i never try voodoormi but many people report sucess

u need test
