Hello. Okay so her is the case. I have a macbook late 2007 model. A couple of days ago I was working, and the mac was running on battery power. All of a sudden it just died, and did not turn on again. I plugged in the power chord and turned it on again. Then I noticed the battery was not charging, so i pulled out the power chord to see if it would run on battery, but it just died. When I turned it on again the battery was charging but extremely slow! It was 86% charged for almost two hours. When I plugged out the power chord again the mac was still on and ran on battery. Yesterday the same thing happend again, so I decided to try my other battery. No difference. I have tried to reset the SMC many times, but nothing seems to help. Does anyone know how to fix it? I know it´s something with the smc, cause I have two battery to test with. Sorry for any typos, I am from Norway, hope you understand.
