I am currently battling this problem. On four occasions I have fixed it only for it it occur a short while later. My

My
problem seems to be associated with the ribbon clamp at the front end of the trackpad cable (under the front edge of the MB. When I re-seat it I get full functionality back (on one occasion only the keyboard came back however). The problem first occurred after carrying the MB in a bag against my back on a brisk walk, so it got a bit of a shake and some bending load. Since then it has become more and more fragile - I daren't move it now! The ribbon has a couple of stress relieving kinks in it next to this end which would normally reduce a pull on the connector if the battery where to move (or swell), but these create the unfortunate consequence that if pressed by the cover if it is slightly dented, by my back for example, will produce quite a large force to dislocate the ribbon end. I

I
have inserted a little pad under the ribbon end this time to try to maintain some upward pressure on it to resist better any more compressions. Will it work for long? Lets see.. (I would add that there is no difference in appearance between a working clamped ribbon and a non working one, it is something very subtle and sensitive that is going wrong here)
