Hi, hoping to find someone that understands the internal workings of a macbook pro to tell me what would of physically happened to my laptop. My macbook pro (15" late 2008) charger developed a loose connection at the magsafe connector. So foolishly i cut it off took it apart and re-soldered. Obviously i must have done something wrong because i connected it and nothing happened. Now regardless of which psu i connect i get (not charging) next to the battery symbol and the charging lights on the magsafe's dont light up. However when i connect one of my other chargers it is powering my laptop and the power source is recognised as "power adapter". I left it plugged in all of last night and it did take some charge, the battery was upto 48%. But obviously usually it would be fully charged in an hour. Any thoughts? Thanks.
