Battery is not charging despite SMC reset
The laptop will boot/run fine on a charged battery. It will NOT boot from the charger alone, nor will it charged a battery that is plugged in. Already tried resetting SMC and replaced DC-in board and charger.
This is a water damaged laptop (Received in that condition), that has been cleaned of corrosion, dried, etc.
Verified on other machines that the battery, DC-in board, ram, charger, etc all work.
The system WILL boot from charger ONLY when by-passing SMC.
I am not familiar with testing a board with a multimeter but checked the fuse next to the DC-in board and got a reading of 0, with the charger plugged in. I am confused since I thought that meant all power to the board is shut off by that main fuse, however, i get positive readings on the meter at other random places on the board.
I looked at the power-architecture pdf of the system as well and not sure what to make of the circuitry.
Not sure where to go from here. Thanks in advance.
Okay, wasn't sure how to post a screen shot onto my comment so i uploaded it online. Link: http://s27.postimg.org/qgvdtt4ur/photo_1...
