Noisy "F" key if I apply too much pressure on the f key - is normal? HP ProBook 4540s

When I hit the f key too hard on my new HP ProBook 4540s, it makes a sound like it's "stuck"; but if I use a lighter touch (much lighter touch) I don't hear it. In the course of normal typing, though, the f key makes a click noise all the time - I just got this laptop yesterday - should I take it back to get it replaced with another that doesn't have an f key that makes such sound? I find it annoying.
