I have a brand new battery and it won’t charge while plugged into the power supply. Green light barely visible. System runs off charged battery and off power supply. After running for a while it shuts down yet it doesn’t get hot. Does it sound like a bad logic board, and is that something that can be fixed? Thanks in advance for any help.
Download and run Coconut battery to find out its status. Are you using the AC adapter that originally came with the computer? This sounds like you are not getting sufficient power to the machine. It’s the AC adapter, the mag-safe port or the battery connector. Take a tooth pick and push the male leads located in the AC adapter tip to see if they are extending completely. Examine the Mag-Safe port for corrosion and/or blockage. Also remove the battery and look at the battery terminals for corrosion or damage. http://www.coconut-flavour.com/
I’m a little unclear on the details of the problem, but does the system work 100% fine with the old battery (hopefully you have it around to test)? If so, the new battery is the problem. I’d definitely try a different battery before proceeding. When you remove the battery, is the AC adapter light bright green, and does it power the machine? If so, I wouldn’t really suspect the AC. I’ve never seen an AC that worked fine, yet was responsible for a battery not charging. It’s worth trying another, but it’s not likely the problem. Does the “green light barely visible” situation only occur when a battery is connected? I’d suspect your DC-in…either that or the internal battery connector, and if neither of those, then the logic board itself. Sellers often state that their DC-in boards are tested and working, but realistically they are difficult to test, and most sellers don’t bother and just cross their fingers.
