Blackberry 8520 not charging

[boylan87]

My blackberry has stopped charging after i dropped it, i use my old one to charge the battery then swap them over at the minute basically just wondering if its fixable

My old phone is a 8520 also just the case and housing are really battered thats why i got a new 1

Ordered the screw driver to take it apart and have a look myself as i have some knowledge of doing this sort of stuff

Can anyone tell me what they think the problem will be or what part i mite need because i will take it from my old phone thanks
