Today one of my pogo pins melted while connecting an PPP with an empty battery to the keyboard:

This is a weird thing and if this happens to you, here are some pictures on how you might fix this:
1.) remove all screws on the backcover, including the one behind the white sticker:

2.) Gently remove the whole back cover:

3.) Clean the PCB contacts with alcohol or some special "Kontakt" cleaner:

4.) Take a replacement pin (or clean the burnt one) and try to model a new surface with some glue and bring it in place (its terrible work when you have big hands):

5.) Wait 24h until the glue is really dry (I know, they say it takes seconds to dry, but thats not true), then clean the pogo pin from any glue with a thin file or sandpaper:
