E7270 Nice but Trackpad issues

Recommended Posts

Hi,

I've got myself a nice Latitude E7270 refurbished, and manage to have everything working with dynamic patching via Clover, and the replacement of the intel wifi by a DW1560.

 

The card reader is not working since it's an rtsx, I tried sinetk driver to no avail ... anyway I can go without it.

 

 However the trackpad is still costing me long hours trying to get what I had on the E7240, a trackpad with the Apple trackpad prefpane working. I tried almost every kext I found on this site (and others) to no avail. I got one that works fine, but doesn't show after sleep ... keyboard still works, fingers on the trackpad generate random right click patterns. So I reverted back to the basic ApplePS2Controller kext.

 

The log show grep identify the touchpad as an ALPS V8 TouchPad with ID: E7=0x73 0x03 0x28, EC=0x73 0x01 0x13; I.m wondering if this is a I2C trackpad or if it can still attach reliably with a voodoo kext to PS2.

 

I would like to keep most of the patching thru Clover, and that's why I didn't modded the dsdt and ssdt. 

 

Any thoughts - help appreciated.

Thanks Hervé and Jake Lo! I will continue my tryouts with the trackpads ... and study the api methods, looks like the trackpad is not woken up correctly.
