Hello everyone, I have a Macbook Air Original (2008) and lately I ran on some problems. I will give you the steps from which the errors occured. 1. I worked for 2 hours on my Macbook Air, at night and I left it on for the whole night (I fell asleep) 2. When I woke up (at morning) the Macbook Air was turned off. 3. I tried to turn it on but nothing, the Macbook Air refused to turn on. 4. The magsafe light was dim-green. 5. I left it without the magsafe on for some days. 6. After some days, I plugged the magsafe on, the light turned on (yellow). 7. I turned on the Macbook Air, everything was working! Did not have problems. 8. The battery icon showed that the battery was at 0% 9. Tried to shutdown Macbook Air from the drop down menu. 10. Macbook Air restarted instead of shut down. 11. Unplugged the magsafe. 12. PLugged again the magsafe. Dim-green light. Nothing. Macbook Air did not turn on. 13. Left it for 3-4 days without plugging the magsafe. Battery swelled up. Removed the battery. 14. Tried to turn it on again. Magsafe light yellow -> Macbook Air works. --> tried to shutdown -> Restart Loop instead of shutting down. The last step (No 14) is the problem I have right now. The Macbook Air does not have a battery anymore (I removed it, it was swelled up). So.. When I let the Macbook Air for 2 days alone, then, the light of the magsafe turns yellow (bright yellow) and Macbook Air turns on and working in Mac OS X (I reinstalled Mac OS X Mountain Lion just to see if there was an OS problem. The problems remain.). When I try to shutdown the Macbook Air, it restarts instead of shutting down. If I unplug the magsafe and try to plug it again on, the light goes dim-green and cannot turn on. If I let the Macbook Air alone for another 2 days, it turns on without a problem. Still, cannot shutdown. Restart loop. Again and again. Tried the Command + Option + P + R when turn on Macbook Air, pressing the keys for a period of time that I hear the "Mac OS chime" twice. The problem remains. Can you please help me? What can I do to save my Macbook? Thank you very much.
