Good evening guys,
Can anyone of you kindly explain to me what's this screw sticker about? There is no "warranty void if broken" text on it so what's its purpose?

Also you may noticed that the S/N sticker is starts removing itself due to non homogeneous surface on which is applied thus more subject to dust gathering underneath. Will that void the warranty? I tried to contact the Asus support but they didn't respond yet.
I appreciate in advance your help.
Best Regards
