On my Samsung Laptop NP550P5C, sometimes when I press the number pad 0, it simply does not return the number zero. Instead it acts like a right-click.

I tried switching the Num Lock, but it didn't help.

I had to google around quite a bit to find a solution. So this is for posterity.

On Samsung laptops, it can be solved by switching the Fn Lock key, which is found on the right side of the F12 key.
