Hi all, I am a newcomer to the forum and have run into a wall with my situation. I'll try to keep my question very simple with all the crucial details and hope some of you experts can help me My logicboard failed in my 2.8 ghz 17 inch MBP Core 2 Duo and I had it repaired about 3 months ago. I just got around to getting a new battery as the battery was dead when I got it back from repair because it was sitting for about 2 months before I sent it in. I just purchased a new one from iFixit. It is an Apple brand battery. Since i got it back from repair, I was running it in the meantime with the dead battery inside while it was plugged in for the last few months. My problem is that after I installed the new battery, it will not charge. It appears the battery itself is fine as it is labeled "Normal" in the system profiler. It does say "Not Charging" in the tool bar and has the adapter icon inside the battery icon. The light is amber on the mag safe adapter which generally means that it should be charging. There is absolutely no charging going on. The battery came with a 70% charge and I am at 65% and had it plugged in all day. I have done all sorts of resets (SMC and PRAM) and even reinstalled the OS to be sure. I borrowed my friends charger to see if that was the problem but it wasn't, same thing happened with his. So its not the charger. Do you think I bought a bad battery? Or do you think maybe my MagSafe DC-In Board could be bad since I recently had my logic board worked on? I don't want to take it to Apple because they have never lived up to the name "Genious Bar" in every instance I have had an appointment. Has anyone else had this problem? If so, what was the issue? I am afraid it could be my logicboard again, but I am not sure. I am hoping it is either the battery or the MagSafe DC-In Board. Please let me know your thoughts, I have about 2 weeks to return the battery incase you think its the battery.
