Actually I once made a mistake when screwing back together A1k keyboard. I learned the hard way that silver screw (shorter one) was supposed to go on specific location on upper right corner (when you view keyboard from downside). I screwed all screws only to notice small dimple of protruding screw on top of keyboard case. I felt very stupid that moment, yes indeed.
So 3 golden color plated screws are little bit longer ones and silver colored is shortest for a REASON! That was my lesson...
