Why won't my MacBook charge?

When I plug in the charger to the charging port I literally have to hold it at a weird angle to get any charge at all. If I just let it sit how it is supposed to, my MacBook just shuts off because it won't charge.

Is this something I can just clean or do I need to have it fixed? Also how much would something like that cost?

Is this a good question?

Cassie, can you supply us the last 4 digits of your serial number so we can figure out which model you have. Most likely you have either a bad charger (cable/connector) or the mating connector in your system needs to be cleaned or replaced. Once you tell us your S/N we can work out these details.

Make sure the connectors on both the charger and the MacBook Pro are clean using a Q-Tip damped with some isopropyl alcohol. Hopefully thats all it needed.

If you are still having problems I would start by trying a second charger to see if that is the problem.

If it still hasn't helped then it looks like the I/O board is worn or damaged. Review this iFixIt guide Left I/O board Are you able to take your system apart to replace this part? If not, it's best to have an authorized Apple repair center or Apple Store deal with the repair.

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 magsafe component was exposed. I simply made another gasket from electrical tape and reinserted the unit and I am happily typing this message on the unit and it is maintaining between a 97 to 100% charge.

Thanks for all of the information Ifixit.

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 metal edge with a current going through the IO device. This was taken off before i reassembled the computer.

I did not put the i/o component back into place because it was easier to test the unit when it wasn't reinstalled. When the light started to burn bright green, I knew it was shorting out somewhere. I then reinstalled it and found i had a faint green light again and knew i had to take the unit apart again and redo the procedure until I found the short and finally determined that the little grey gasket on the magnetic end of the I/O device was not doing its job and I took it off and built my own little gasket out of electrical tape.

I was pleased because the repair shop I took the item to said it was a logic board problem and the logic board would have to be replaced which would have cost more than the value of the computer. Hope this helps and if anything I wrote is unclear, please tell me and i'll try to rephrase it.

Hello slopereader! Pls I'd like to ask how you built your own replacement for the grey gasket on the I/O device using electrical tape. I think I might be having the same problem as you had.

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.
