Answer to: Why won't my MacBook charge?Hi, I went through the Ufixit pages and removed the I/O board. I then made sure it was plugged in where it had to be and then I attached the charger to it. It started to glow bright green but of course when I'd put it back into place, it would not work so i simply built a gasket out of two layers of electrical tape. Use a blade to put a slit in it and cut away the excess.... If you find it is glowing bright green then it's working of course. if the metal is touching your computer case, it'll short itself out. You can tell if it is the motherboard by simply charging your computer on another battery and see if it will turn on and run your computer and you know your mother board is not fried. The Apple store basically wanted around 1000 dollars to replace the motherboard and i can buy a used macbook pro for that cost.
Answer to: Why won't my MacBook charge?Rodney, we have exactly the same model although mine does not have the little heat shield in the instructions to which i've created a link below. I didn't end up replacing the I/O board. I played with it until I determined the only thing wrong was that it was shorting out. First, if you know someone with exactly the same model, have them charge up your battery and if your computer boots up fine, then you know for sure it's not your logic board that is bad and that it's most likely your I/0 board that's faulty. Once you determined that, i used the ifixit directions to remove the I/O board and then, created my own little gasket out of electrical tape over the magnetic piece of the IO device. I then without putting the computer back together, reconnected the I/O board cable (picture 22) and connected the power supply connection in picture 17. i also used a piece of electrical tape to cover the edge of the metal chassis so I could ensure while the I/O component would not short out should it happen to touch the me...
Answer to: Why won't my MacBook charge?Excuse me if this posts twice but I'd like to share my experience with you. I used my son's bad charger which we had to force into the magnetic slot and which resulted in only a faint green light appearing which of course didn't allow for the unit to be charged. I did buy a new I/O unit which I installed but it didn't seem to work either. I knew the motherboard was not bad so I tried various things to make it work. I bought another Macbook pro but it is the 17 inch model so it's a little difficult to lug around and I wanted to see if I could fix my 15 inch model. I disassembled the Macbook until I could easily take out the I/O component.(using IFIXIT directions) Once I did this I plugged it into the motherboard only without putting it back into it's proper position. I found that the bright green light came back on and when I'd reinstall it, only the dim green light would reappear. Once I found that out, it was clear that something was shorting out and what I found was the gasket covering the magnet of the I/O...
