First thing: Check the little ribbon cable between the keyboard and the mainboard. Where it pluggs into the mainboard is not very secure.

Hi 

It looks like what happened to mine...

I sent the CZ1 to a tech, but it is still there.

The problem seems to be a CI that controls the keyboard and is hard to find...

He told me he finds one (after several months) and it fix up the problem, but it was heating up very much, and he would have to find another....

 

It's a real pain...
