If you carry the laptop in a back-pack, then over time the fabric may have caught on the badge and pulled it up.
Because of the rubber coating on our machines, not much will adhere to the outside. You could probably get away with pulling up the damaged part of the badge, straighten the bent metal with pliers or something, and then glue it all back down with a dielectric adhesive (probably overkill, but I use it for everything that shouldn't conduct). It depends on how much you would spend otherwise having it repaired, and how much it will bother you to have a faint seam in the badge later.
