Macbook Pro, 13" A1278 Model, model with internal black battery Will not power on at all. Super dim green light on magsafe charger. Background: System wouldn't power on at all. Took apart, removed battery, motherboard, all connections, looked for corrosion, dirty connections, etc. Put it all back together, plugged in charger, system powered on and booted up just fine. Logged in, messed around, shut it down. Let it fully charge for about 2 hours until charger light went from orange to green. Unplugged charger, booted system up, no problems at all. Logged in, messed around for a few minutes and powered it down completely. Left it off and unplugged for about 5 hours. Went to power on and nothing. No lights, fans, nothing. Plugged in charger and only got super dim green light. Still wouldn't power on. Tried all of the PRAM, SMC etc resets. Nothing. Battery indicator lights don't show anything when button is pushed. Took it all apart again, did the same thing as before. Put it back together. Nothing. Disconnected battery and plugged in charger. Still dim green light and doesn't power on. Took charger and plugged into a working macbook. It charged that macbook just fine. Had solid green light on that one when fully charged. Unplugged it from working macbook and plugged it into dead macbook and the light went fully green. Still didn't power on. Took it apart again, unplugged all connections, put it all back together, plugged in charger and dim light again no power on. Unplugged charger from dead macbook and plugged into good macbook and solid green light. Then unplugged from good macbook and plugged into dead macbook, solid green light again but still no power on. Tried cleaning magsafe jack, reseating it to make sure it was getting solid connection, no dice. Completely disassembled again and replaced the magsafe jack with a good one and put it back together... dim green light again. Also during this time I replaced both RAM chips with good working ram chips and still no dice. Now for the question: Any ideas? lol Thanks in advance, and before anyone says it, there isn't a genius bar within 2 hours of me so that is out of the question. Thanks!
