With these Wacom tablets, the large ones specifically there are about two or more separate boards that are easily removable.
The main one in question would be the charging port board. Luckily disassembling these is not a problem as you basically only need to remove a cover to get to the board usually.
The harder part would be removing the charging port and soldering a new one on. With a rework station and a soldering iron you can get it replaced. You can buy a rework station kit for about $80 online.
