The power button on my Nokia N9 became stock, so I disassembled the device, and there's the chassis: http://www.imagebanana.com/view/ht53hmyn/12090026.jpg

As you can see there's a missing orange dot at the right. I found the little orange dot but it seems pretty impossible to get back on...

How would you recommend to repair it?

Would you recommend to buy a new chassis and if yes what is it called?

SOLVED. See last post.
