What I did is to reset the SMC and while the battery plugged and the magsafe plugged, wait a few minutes. When I finally got the magsafe, after a lot of testing, I could manage to "normal" boot up (but still no charging).

With the battery drained, I couldnt boot up the mac but with the 10 segs power on trick. I havent updated this because I havent got a genuine magsafe charger until Febraury. Yet, I think its a good idea to people know the pinout layout if someone is trying to revive a problematic macbook air battery. The system profiler says that the battery is not charging, but I can see with coconut battery that it really is charging. Another thing, it's that I understand that if the battery is charging the magsafe light should be amber and not green. I managed to get an original magsafe 60w and I have green light, but its almost dark and in my friend macbook the light is much brighter. I can turn on the lap with the hp charger (18v 4amp), but still there is no light (the connector is from an original magsafe) and you have to remember I can get light in the macbook of my friend. There is still something that bothers me. Now I can turn on the macbook air without doing the bypass, and it has 662 cycle with 4660mAh from a total of 5500mAh from the original design. The battery connector to the logic board has to be pretty pretty into the plastic connector for the logic board to recognize it. I found the problem with my lap, is really silly, but it's what it is. I've tried 14v, 16v and 18v chargers, none of them turn on any of the leds of the magsafe connector.Ĭan somone help me letting me know where are the energy pins problem was I couldnt see the battery because I couldn't turn on the lap without doing the bypass which makes the laptop to dont see the battery. I know most probably everyone is gonna say "buy a new battery", but I kinda know the battery is functional, because the early times I could turn it on, the battery held a little power and I could turn on the mac without the charger. So I want to manually charge the battery, but I dont find the pinout layout anywhere. I know Im doing "ok" the SMC reset because I did it too while the MBA it's on, and it just power off the laptop, but doesnt let me turn in it on again unless I do the 10 segs power button smc reset Upgrading the EFI and SMC firmware (osx say's it doesnt need that update) Resetting the SMC with the 10 segs power button (in fact, everytime I want to turn on the mac when disconnecting from the AC) Resetting the SMC with the shift command power

In fact, the led of the magsafe connector never turns on in any color, but it does in a macbook pro of a friend. The OSX tell's me that there is no battery connected. The hard drive was ok, it only needed a zero's write format. I managed to turn it on using the old smc trick, pushing the power button for 5 segs without energy in the charger and then connecting the charger to the energy and having pushed the power button for another 5 more seconds. I've been searching the internet for a lot of hours and I can't find the pinout layout of a macbook air battery.Ī friend gave me his old macbook air (Macbook Air mid 2009 A1304 1.8ghz non ssd hd, 45w charger, battery A1245), which didn't turn on and the genius told him that he need to replace the hard drive and some internal component (I assumed the dc jack in).
