Hey Tristan,

Yes, it has been a while, but as I recall this cable is underneath the 
hard drive.  The  cable is supposed to run NEXT to a support stud that 
comes off the metal frame, but this cable is prone to slipping over this 
"stud."  Once the cable is between the "stud" and the top plate of the 
chassis that houses the keyboard, etc. pressure on this top plate near 
the track pad can "crush" the track pad cable between this "stud" and 
top chassis plate.  I guess this "crush" can cause a short that causes 
this "freeze."  Worst case, this cable could sever and I think that's a 
big deal, but if your computer works occasionally, then I would bet that 
this cable is just getting shorted out as described.

Best of luck.  It's a great machine when it works.

Sincerely,
Brad
