Hi,
At home, I run my MacBook in clamshell mode (closed lid, external display).
This works fine when you're connected to the power adapter, but it doesn't work when running on battery. That's how it's supposed to be and Apple has some kb entry on the issue. But it's also lame.
You can prevent the machine from sleeping when closed by running InsomniaX, but then it'll assume the builtin display is still active, so you end up with a two-display setup when you really only want the external. This is obviously less than ideal.
So, is there any work around, hack, utility, black magic that I can use to make it run in clamshell mode while strictly on battery power?
Also, bonus points for a solution that makes the AC status not affect the machine state at all. (Like, you know, it does normally, when not in clamshell.)
