Chosen Solution
2 years ago it has been replaced the logic board, after a few months it was off and is no longer running. now Apple does not want to replace the logic board with the extended warranty program ( i will go to my lawyer). when I connect the magsafe first light is green, then orange and then goes out. does not charge does not turn on no noise the battery LED does not work i tried another magsafe (from my macbook pro 13) but does not work I tried disconnecting the battery cable for 5 min and then reconnected, the problem continues. do you think it’s a fuse problem? or a magsafe connector (internal circuit) problem? or other kind of problem? please help.
It sounds like the PP_3V42/G3_Hot Internal Circuits of your motherboard, or maybe the System Management Controller are shot. I would suggest either getting a motherboard replacement from Apple (if you can afford it), or having a 3rd party MacBook repair store who specializes in component-level motherboard repair to take a look at it.
