[T60p] Trackpoint issue

[Poukin]

Hello,

I have a new issue since i updated my t60p. I opened it to add a SSD and a new processor (T7200), and since i reassembled it, my trackpoint doesn't work unless i unplug the palm rest (so the touchpad id unplugged).
If I plug the palm rest, the trackpoint stops to work. It does it even on a linux live cd, so it is not a driver problem.
In the bios both trackpoint and touchpad are set on "automatic".

Do you know this issue guys ?

Thanks
