Most of my A600 Key´s did not work. (maybe 10% did work)
I tried 2 Motherboards. Same result on both.
Not sweet at all
I thought i need a new Membrane/Ribon cable.
But then i took a very sharp Scissor and i cut 1mm of the Ribbon Cable´s End.
Result is that all Keys are working now.

PS: Funny, Flip79 and i had the same idea
