    Hi everybody..


    I think i just found the solution.. 


    1) connect the external display (both are working), and make sure the external is the primary display.

    2) use a magnet to shut the internal display off (only the external is working by now).

    3) lift up the magnet and quickly close the lid.


    I succeed using the clamshell mode using this method. Hope to hear good news from you all.


    Macbook Air 13inch 2011

    OS X 10.8.2

    Hi, I have the same problem with an MBA 11´. I realized the problem arises when the mac is not connected to the electric supply. Once connected it to the power supply and it seems to be working fine now. I also have an MBA 13, and it doesn´t have this problem.

    I tried "sudo nvram -d boot-args" and reboot and it still was shutting off.  Then I plugged in Macbook Air to the external power source and I can now work in clamshell mode without the Mac going to sleep. Apparently the external power needs to be connected for the clamshell mode to work.
