Razer Blade 15 has loose piece rattling around inside: known problem?

I have owned my laptop for about 1.5 years (it is out of warranty) and regularly take it to and from work in a backpack. I just noticed that there seems to be a screw or something small and loose inside the case that is moving around and rattling when I pick up the laptop, although the laptop still functions as of now. I will open it up as soon as I can buy the necessary screwdriver, but I'm not sure how to proceed beyond that if I can't figure out where the piece came from or if the piece is broken off and irreplaceable. Thus, I was wondering: is there any known issue like this, such as a piece that is known to break off or a screw that is known to come undone? (I tried searching the forums for similar issues, but I only found one related thread in which this was observed in a brand new laptop and because the laptop was still covered by warranty, the conversation was redirected to PMs and didn't provide any info.) Thank you!
