Gently - and with the power disconnected, yes.  
Hi, I recently got a new battery from Parts People for my XPS and the battery cable won’t connect to the system board.  The right side goes in, but the left side won’t budge no matter how hard I try to push it in.  What can I do to get them to connect?  I was able to remove the dead battery just fine, but now I can’t get the new one to fit in.  Thanks   [IMAGE]
