Power Button problem

Hello everybody, 

First Happy New Year and all my best wishes

I have a Dell XPS 13 9360, that fell on the floor while in its case/bag. Nothing was damaged on the outside, but on the inside the power button actually got damaged. It's not in place anymore, meaning it's moving. It seems the power button sticks to the board with some kind of glue, and the shock (very mild) kind of blue the glue up leading the button to be moving. 

I also want to signal something to the Dell's support team. I bought this computer 2 years ago, and at first when  I used to turn on the PC, the power button used to make a "click" sound, meaning the button went to its original position. However, as time passed by, when I turned on the computer, I needed to press twice the button, cause it kept being stuck (and the "click" only while pressing it the second time).

By the way the button still works,but I don't know if it will last. 

Is there a way to replace the power button ? Do you recommend any sites ? 

Thanks in advance 

Best regards
