Hi all, Hope someone can give me some constructive answers please. I have a Macbook Air Mid 2011, Its a year or so old, with Applecare warranty till Sept 14. I had only had this a few weeks when it took a light water spillage. Wouldn't then start up, as i expected, needless to say my son got a good telling off. I tried the old taking it into Compuserve here in Ireland and they were having none of it and wouldn't do the repair, new logic board they said, They didnt even try to power it up, i was there. Anyway i claimed another on my house insurance so all good, I left it to dry out in a spare room and forgot all about it as i work away alot and had my new machine. Well this is over a year later and i realised i still had this thing and found it and tried to power it up, so i plugged in the magsafe and the magsafe light was flashing from green to red then green then red and so on, Low and behold the bloody thing started up. The magsafe then went to green, Machine booted up... for about 2 minutes,,,, then powered off. I did alot of research online, so i took off the back cover, and had a look at the Logic Board, there were only 2 tiny bits of corrosion which i gently removed with isopropol 90 odd percent alcohol and put it all back together and left it to dry out again. Just tried it again today and it did the same thing. Came on for a couple of mins then switched off. There is no charge in the battery, its seems to get a minimal charge into the battery then power itself up, the machine is fine, everything works, Screen, Keyboard, Keyboard back light, all the keys work, everything, but just wont charge the battery and then it powers off again, I have done all the different kinds of reset key combinations, smc, nvram,pram. Before i spend any money on it would anyone thing it could be the I/O Board. I have removed the battery and plugged it in, had the back off whilst i did this, and the fan spins a tiny bit with a little squeak noise but NO Startup this time, only starts up with the battery in and it seems to do it on its own when it has drawn some power with the magsafe switching from red to green. Any ideas anyone. I wouldbe delighted if its the I/O board as they are cheap enough to get and i can do that myself. Thanks.
