I swapped the bottom half of our clicky keyboard XO-1.75 with Tank, a
prototype XO-1.5. The mouse problem followed the touch pad with
identical jumpy behaviour when plugged into the XO-1.5. The XO-1.75
performed normally with the XO-1.5's touch pad. The touch pad assembly
is different in these two laptops. Is there anything you want me to
record (model number? from where?). One has a blue circuit board and the
other a green one, I'll post photos shortly.

The actual swapping operation was quite involved. I think maybe it would
have been easier to unplug at the motherboard end? The clicky keyboard
has 5 extra screws not mentioned in
http://wiki.laptop.org/go/Disassembly_bottom which had me stumped for a
while.

I'll update #11171.
