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!
