My handluggage - fully packed with laptop in the back weighs around 16kg - but never have I been asked to put it on a wheight-scale. I have it on my back when I come to the check-in counter, and try to look like its lite as a feather!
I mainly travel from Europe to the red sea or asia. Only one time in Borneo, have I been asked to put my handluggage on a scale and when they asked whats inside and I said camera and computer - well they didnt mind anything about it.
