Hi Jayeff,
Thanks for the input. I have looked at the video and a couple others doing tear downs of the S7 and managed to get a hold of the service manual.. Not for the faint hearted indeed. The keyboard itself is clearly a membrane with keycaps. No fixing there.
I'll engage Acer (minimum 2 week turn around) but I'll let them dig into it properly and cover any mistakes made on a very tight chassis.
Thats again.
