Computer runs perfect on battery only. It does not take charge.
When it 's plugged into de wall, it doesn't take the charge nor the light in the mag plug stays lit. The little green light blinks only. Otherwise, when it works on battery, the functions are normal. The battery is almost new. The charger works fine in other computers. What do I need please, and how much it costs?
Thank you.

Have you tried replacing the battery connector? It's a cheap part, and worth a shot. They do occasionally go bad and cause various issues. Just search eBay for "A1150 battery connector"...th
Also, I know you said the battery is almost new, but do you absolutely know it is good because you've seen it charge in another machine? If you haven't personally witnessed it charging in another machine, you don't know for sure that it's good, and it could therefore be the problem.

If there's no change after replacing the I/O board, I'm afraid the problem is the logic board itself. I still have an iBook that does exactly what your laptop does - everything works except battery doesn't charge. Logic board replacement is expensive, so I just charge the 2 batteries I have in another iBook and shuffle them around to the noncharging unit.

O.K guys. Thank you for your support and suggestions. Finally I've got it fix. The problem was in the Left I/O/ board. The first time I connected the computer it didn't work. It was doing the same as before. A dimmed blinking light in the mag. connector. Afrter i spoke with one of the guys, unfortunately I don't recall his name, he suggested to check the connection of the ribbon cable from the Left I/O
board to the logic board. He was right. The connector on the Logic board was warped and didn't connect properly. I removed it and straighten it up, re-connected it and BINGO, my Macbook Pro is working again. I switched again the Left I/O board just to make sure that the old one was bad and I finally realized that it was the case. The replacement of the I/O board was needed. Thank you all for your help and God Bless.
I received the parts and tools needed for the replacement of the Left I/O Board and followed the instructions exactly as instructed. The result is the same blinking green light and now the computer doesn't power on (The battery is showing only one light, so, it may be drained) What can I do? What could've go wrong? Was the diagnostic wrong? Please help me.
JORGE BARREIRO,
If the battery gets to low the machine will not power up. Leave it plugged in for an hour, let the battery charge and try again.
mayer,
Thank you Mayer for your replay. I don't think the battery is charging, since the mag plug doesn't show a consistent green light. It's been plugged for about 40 min. now and the green light is still blinking.
JORGE BARREIRO,
Hello Mayer, the situation is the same, battery not charging, green light blinking and it's already 1 1/2 hours. What should I do?
JORGE BARREIRO,
Hello Mayer or anybody else, I desperately need help, please!
JORGE BARREIRO,
You have a short either in the AC adapter or the DC/IN port. You said the AC adapter worked on another machine, but I'm beginning to doubt it. Try another AC adapter on your machine.
mayer,
The AC adapter is fine, it was checked up at APPLE store last week.
JORGE BARREIRO,
You went to an Apple store and they couldn't tell you what was wrong? Did YOU SEE your adapter plugged into another machine and not blinking? What happened when they plugged their adapter into your machine? What did you SEE?
mayer,
The Apple store doesn't give you a diagnosis. There's a flat fee of $ 350.- and they will fix the computer. At least at the store on Broadway and 67th St. in NYC. I asked the desk associate, What's wrong? Her response was: something with the logic board, but I don't know what she meant that or I/O board. These people are sales, they know little about hardware and you can't talk to the techs. Continues...
JORGE BARREIRO,
Before this, last January, while in South America, when the problem started I took it to the Apple store and they diagnosed a bad board. They gave me an estimate of $ 170.- only that the next day they called me and said they had to order the Part from Miami and it would take 30 days. By that time I was gonna be home. At my arrival home, a friend suggested me to contact ifixit.com They suggested me the Left I/O Board and some tools, and you know the rest. It seems to me that something else is wrong and now, I purchased a part that I may not need. I'm a professional musician, with very little work, and in need of my computer. I tried to do it myself, but It didn't work. What do you suggest ?
JORGE BARREIRO,
There is a possibility that you got a bad I/O board. Try starting with the battery removed. If that fails we need to start over and question everything. If they quoted you $170 it had to be for the I/O board as the logic board would be much higher. Use a multimeter to test the output on the board when the charger is plugged in. Test the adapter output also. Just remember to test the AC with the multimeter set on AC and the board with it set on DC
mayer,
What I/O board are you talking about. The left side has been replaced and I don't even know if the older one was wrong. How can it be tested? I will get a tester this evening and try to conduct the tests you've mention. I would appreciate if you could be more specifical of where to test. I'm not a technician. I'm just bold and if I don't know it, maybe I can learn it kind of guy. I appreciate your help. Thank you again.
JORGE BARREIRO,
In addition, what can of numbers I'm looking for on the tests. I assume the A/C is to look for a short, but the DC?
