I had better type this up before it happens again, this is totally weird. I just got my new battery, a replacement and I'm charging it now. But while its charging the power connector keeps turning off and I have to unplug it and then plug it back in again for it to work. After this has happened, the internet doesn't work and I have to turn airport off and then on again for it to work as well. It has repeated on me 3 times now in the space of an hour. Anybody ever have this issue before? 1st EDIT: If it is the power brick then it seems it is a common issue, I've just been to the Apple Store and there are tons of negative reviews for them, anybody know of any reliable 3rd party alternatives? 2nd EDIT: 4th time while editing this post. Argh.
