Galaxy Nexus does not start at all?

Hello my Ifixit friends! A customer brought me a Galaxy Nexus (I9250) with a rather strange problem. He had problems charging his phone over the past month or so, saying he had to hold the cable in a very specific way for it to take any charge. Then, it stopped taking any charge at all.

I assumed the problem was the charging dock, so I changed it out to a new one and attempted to charge it. No luck. The battery looks fine, however I do not have a new one to try. (I've ordered one now, should come soon..)

I've checked the motherboard for any signs of water damage but it looks beautiful. Despite that, I cleaned it with some Isopropyl and a soft brush. Any ideas besides the battery? I was thinking about changing out the screen, to see if the screen could in some way be damaged. (Customer claims he's never dropped the phone, and when I look around the edges it looks to be a true statement.)

I'm at a loss except for possibly the battery, which wouldn't make sense from the information I've received from the customer...
