When I woke up this morning the magsafe was no longer lit with a green light. It is supplying power to my MBP, but doesn't charge the battery any longer. Very odd indeed! I have performed the following troubleshooting steps: - Reset SMC: Didn't help - Tested a brand new battery: Didn't help - Tested another magsafe: Didn't help - Tested different power sockets: Didn't help The MBP is receiving power when the magsafe adapter is connected, but not charging the battery! I know the MBP is about 3.5 yrs old, but this is extremely frustrating especially as it has happened for no apparent reason. I guess that my testing has narrowed it down to a hardware problem to do with the logic board. Any suggestions?
