Turning off Macbook Air Display with External Display Lion v2

[harisenbon7777777]

come one ! the NEW 2011 MBA doesn't NEED cooling much. It never gets hot. Maybe a bit warm. Just keep it closed. Don't worry, it is not such and ancient device like that 2006 Mac Book Pro !

@harisenbon7777777 lol... its not that it overheats, but more that the fan kicks in all the time when its closed and make too much noise when trying to record audio or do screen capture videos.

With it open, it doesnt kick on as much.

There is a terminal command for that, so you don't have to use those magnets and staff.

I've read it a few days ago on the Internet.

You should just open the terminal and paste this:

sudo nvram boot-args="iog=0x0"

And after rebooting the laptop your laptop screen should stay black after opening the lid.

To revert changes, just use this other terminal command:

sudo nvram -d boot-args

Hope I helped you guys!

@sc0tt88 Thanks for the tip. I still like to just put a magnet there since it so simple and easy to do.

Hey Rockstar.

I found your video really useful. I was labouring under the misapprehension that Lion wouldn't let me use my iMac with my second monitor as an extended screen. Your video clearly shows Lion letting you do that.

Here's a tip fpr you in return. Regarding your slipping magnet, try using a small piece of 'BluTak' on the magnet. It'll stop your magnet slipping down. What's more it won't spoil the finish of your MacBook Air.

@MTMabowels Thanks for the tip and I will try that ;-)

Thanks a ton for this! My MBA runs much better now without having to power 2 displays.

For anyone who is wondering about the 13" MBA 2011: the magnet that turn the display off is located on the left side above the USB connector.

@crystalceline Your welcome and thanks for sharing the sweet spot for the 13" MBA
