I/O Board or battery failure?
Hello…I’m a bit confused here and need an assist
Here are the cases:
1. My magsafe indicator changes from time to time. If it’s orange, the battery charges and the condition says NORMAL. If it’s green, the battery doesn’t charge and it says REPLACE NOW.
2. When it’s green, if I pull out the magsafe the laptop shut down immediately. And when I put the magsafe back in, the laptop starts automatically WITHOUT ME PRESSING THE POWER BUTTON
3. I can’t use Photo Booth and FaceTime since it says that NO CAMERA CONNECTED…but…there were times it worked (with green flash indicator lit) BUT NO IMAGES APPEAR / BLACK SCREEN ONLY
4. As now, I run this laptop with the magsafe keep connected (green light and battery condition: REPLACE NOW) since it will shut down if I disconnected it.
I've performed an SMC Reset and nothing happened.

I suspected that I should replace either the I/O Board or the battery. Or both. Or...the logic board???
Which one should I came first?

UPDATE!!!
1. I opened the bottom case
2. Pulled out SSD, fan, audio flex cable
3. Tried some route and de-route method while keep connected and disconnected magsafe.
4. Put all together (no 2) properly. Tried dis / connected while tapping flex cable, battery port, magsafe port etc with spudger. Still powers on automatically when it was connected and shut down when disconnected
5. Hopeless...
6. Suddenly the computer beep 3 times repeatedly
7. Disconnected the magsafe and it stopped
8. One last attempt with no magsafe connected, turn the computer on and....VOILA! It works!

The camera still dead, though...
Can anyone please tell me what's going on with my computer?
