INTUOS 5 charging port repair

My Intuos 5 tablet has recently stopped working and i believe the problem is the port connecting to my tablet (it's a USB mini-b [5pin] connector). it seems like the port has wiggled out of place and is not longer connected to the tablet internally, i have used multiple cables and usb ports on my computer so i know the problem must be the connection on the tablet, i bought a wireless adapter to avoid using the cable but it doesn't seem to work, i got a wall charger for the batteries but it wont turn on; the instructions say to power the battteries via cable but i dont see why it'd make a difference. if you have a solution to either of these problems i'd love to know. i'm fairly tech savvy and im capable of repairs however i don't want to try to disassemble my tablet unless i have some idea what to expect
