How do I tell Lion to disable the LCD screen even when the lid is open?

I think it's been established that we would like this option back in some form or other.

True, but please post feedback directly to Apple too: http://www.apple.com/feedback/

Thanks! 😉

Here's the feedback I left:

PLEASE add a "control" or "switch" so when a user has an external monitor connected/turned on/active, it will allow the user to leave the MBP's display OPEN but TURNED OFF (not just turning down the display light, but OFF, [forgot this part: so it is not using additional GPU resources], so it can help heat escape, so is not losing wireless sensitivity, so it can easily be turned back on when the user does want to use it, and maybe even so that keyboard and trackpad are still functional, if that's possible).

I'm sure that someday I'll be forced to "upgrade" to Lion, but until that time, I sincerely hope that you come out with at least one more revision of Snow Leopard, and that it includes this feature.

Thank you!

Already done. :)

Just adding to the list of people who wants this "feature" back in Lion. I already submitted feedback, but want to add my name to this discussion as well.

Can someone help me... for the past few days I have been using the magnet work around....Although today I went to put the magnet in its spot and the screen went to sleep although now my external screen doesnt wake up, and when it does it is only for 2 seconds and goes back to sleep. This never happened, anyone have any ideas why it would be happening all of a sudden

How strong is the magnet? Because the switch is basically two very thin strips of metal which may not function properly if the magnet is too strong.

I've repaired a few notebooks with similar problems. Just a possibility.

the magnet i am using is very weak. Are you saying there could be something wrong with my laptop now because I have been using the magnet?

The thing i can not understand is the magent still put my computer to sleep but normally the external display would just wake up. Now it flash on and then goes back off. I cant understand why its not working now? I hope I didnt break anything by using the magnet. Its not like I can bring it to apple to have them look at it under the warrenty becasue i cant tell them im using the magnet like that

Hi

I don't think it would affect it if it's a weak magent, because after all it's a magnet in the lid which it uses.

So when you take the magnet away what happens?

Exactly, the magnet im using is so weak I hardly feel it make a connection to the metal its supposed too. So any idea why my external monitor isnt working when the laptop is asleep? I have a bluetooth keyboard and mouse. and I am not mirroring the screens, in case that info helps

when i take the magnet away my laptop wakes up and the extenal monitor comes on.

Ok. So, just be methodical, when you close the lid without the magnet what happens?

This will determine whether it's the switch which is faulty or something else.

This needs to be fixed as I speend 80% of my time connected to an external monitor and need the lid open to keep my MBP thermals in check.

Apple,

A user selectiable option is something that should be implemented asap to resolve this issue.
