Hey guys,

this mac came with q7320 shorted i replace and the board comes to life!! But i have a original charger 60W, and this board don't turn on with that! the battery of this laptop is swollen, when i connect the battery + charger when i push the button only appears a icon battery!

this Boards (2015) need a good battery to start well?? Or the board should start with only charger ??

It should start on charger only.
I always test the MacBook boards on the desk without battery and just USB mouse connected.
Do you get magsafe light on charger only?
Post some voltages from ISL6259...
