Could you put it on something (foam?) to make it less noisy? If your family finds out that you sabotaged it could cause serious repercussions.

I just got rid of a small, everyday annoyance. I put a piece of masking tape next to the spot on my laptop where my charger plugs in. This is to make it visually easier to find the spot, and plug into it, otherwise it's not visible unless I lift it up, and look from the side.

Now I can easily plug it in.
