Lid opened notification?
-
Hi,
Is there any notifications that can detect if the lid of a laptop was
opened? if so where can i get the code for them from? -

Are you looking for sleep/wake notifications or specifically "lid"
notifications?

Specifically notifications about the lid

I am not aware of any supported way to obtain that information,
certainly not through a high-level interface such as Cocoa. I could be
wrong.

It might be possible, look at the IOPM.h header file in the IOKit
framework. More specifically look for the key kAppleClamshellStateKey.
Unfortunately I've never used this so I can help you out in that
regard - I only know about it from when I was rummaging through the
IOKit for some basic sleep/wake notifications.

I looked through there and found a few things that might help but ive
never used with this kind of stuff, anyone able to shed light on
these? Im happy if i have to code a small kext to do what im trying
to achieve which at the moment is detect the lid opening and run a
set of commands, but a bigger goal would be disabling clamshell all
together (much like Insomnia, which is broken at the moment)

As this is an IOKit question, you might get a better response on one
of the Darwin lists.

To prevent the Mac to wake-up on lid opening, just enter that in the
Terminal:
sudo pmset lidwake 0
(To turn it on again, replace the 0 with a 1 and)

How to do the reverse? I.e., prevent the Mac from sleeping when the
lid is closed?

I don't think that you can, and I think that's on purpose. You can
prevent "soft" / "idle" sleep though.

Well, I assumed the screen and backlight would be off, just that the
CPU wouldn't sleep. There used to be a trick for doing this, and it
worked well -- no Sunday roast -- but that hole's been "fixed".

Apparently doing this can cause damage to the display if done for
long periods of time - that's from an Apple 'Genius', but I don't
know how true it is.
It used to be that with a powerbook, if you connected an external
display and keyboard, closing the lid simply turned off the internal
display and left you with a tiny workstation.

This doesn't seem to be specific to Cocoa.
