Slide your opening pick or Halberd spudger around the edge of the device to release the adhesive.

When closing the device back up, an adhesive pack can be used to replace damaged adhesive. Be sure to scrape old residue away to ensure a good seal.

Now is a good time to brush away the detritus that collects in the gap during normal use, before any thing is unplugged. This will prevent it from clogging contacts.

If you remove all the adhesive, remove and store the stylus catch, it will otherwise fall out.
