Replaced dc board, now Mac won't power on.
My MacBook Pro 15, mid 2009 has had issues connecting to a power source and charging the battery for several months.
The mag safe adapter would not always light up when connected to the dc in port, sometimes the light would be green when it should have been orange (charging) and sometimes the system would indicate the battery was charging when it was actually draining while plugged in.
I first replaced the power supply, but that didn't seem to make any difference. The battery had somewhere around 1200 cycles on it (I know, that's crazy) and probably held a charge for about 20 minutes but the system insisted it was healthy. I replaced it anyway, and that did seem to make a big difference (for obvious reasons of course), however I still saw some issues with the charger.
Aside from having to occasionally wiggle the cord to make a connection while charging, there was sometimes a buzzing noise and the mag safe adapter would be hot to the touch.
Before I went ahead and replaced the dc in port I brought the computer in to the Genius Bar. They were certain it was just the charger and replaced it again.
So I replaced the dc board, and now it will not start at all. I went through the process twice and same result. I put the old port back and now at least the mag safe cord has a green light, but it still won't power on. Am I missing something? What else can I do?
Is this a good question?
