Chosen Solution
The MacBook Air was was working perfectly fine when suddenly the screen froze and I had to do a force shutdown. After that when I tried to boot, I got a Single Beep with intervals of ~5 seconds. If I press and hold the power button, the light flashes continuously for 4 seconds and then it beeps. The screen is blank and there is no processor or hard drive activity while it beeps. I have tried the ‘CMD+R+P’ and press and hold ‘D’ boots without any success. This is most likely a RAM issue but since the RAM is soldered on, I cannot reset it as most guides have mentioned. This is what the motherboard looks like: http://imgur.com/a/ZYy1l#0 Any help would be really appreciated. Thanks in advance!
Yes–according to Apple one beep means no RAM installed. Link provided. http://support.apple.com/kb/HT1547
I have the same issue. DId you manage to fix your Macbook Air in the end?
Thank you! It works!!! I took the mother board out, took off all rubber and plastic protections, put it in the oven at 190 Celsius degrees for 9 minutes, as NIck Justice suggested. It works!!! My MacBook Air came back to life! Some tips… I used some crumpled paper (like small balls) to avoid the board touching the oven tray. I also let the oven get to the right temperature before putting the board into it.
Hello everyone! Thank you very much to Nick Justice and andregrillo. The first time I cleaned the logic board using isopropyl alcohol in the region of the RAM chips, applied solder flux and tried to heat it up with the heat gun. It worked, turned on and stayed on for about 5 minutes, then it turned off again, returning the beeps. In a last attempt I decided to try to put it in the oven as you suggested, I left it there for 13 minutes at 180-210 C. Worked perfectly! I’ve been using it for 1 day, and I haven’t had any more problems!
