Alienware Aurora R4 Power Button

Hi, recently received my AW R4 ALX, I seemed to notice that the power button seemed to wobble from left to right, I initially tried to switch the PC "ON" by normally pressing it down, nothing seemed to happen, tried to press it several times until I noticed that it needs to be pressed firmly, all way down and then it booted up. was this normal on how the power button was built or was it some kind of factory defect? hope to hear from others with the same concern. Thanks and any replies will be much appreciated.
