I have a white MacBook Core Duo 2 GHz. I use it with an external monitor a lot by plugging in power, mouse and keyboard while it is closed and asleep. Then I can use the keyboard to wake it up. I have read that this is 'clamshell' mode and that it supposedly only works when the MacBook is running off the AC adapter.
My problem (that I can't seem to reproduce) is that very occasionally my MacBook will be stuck in clamshell mode even without the AC adapter, and I cannot get the screen to display anything when I open the lid. The white LED goes off when I open the lid, and it remains on (not pulsing) when the lid is closed.
It happened this morning after I put my MacBook to sleep, unplugged power, keyboard and mouse (not sure what order I did that in, but I will pay attention from now on...), then tried to wake it by lifting the lid.
How can I exit clamshell mode when it's "stuck" like this? Every time this has happened I have had to hold the power button down until the computer turned off, which is very annoying (all programs/desktops closed... aargh).
I have seen this happen to a MacBook Pro as well, so I think it must be a common issue relating to external screens. I couldn't find anything by searching though so I hope somoene here knows what I'm talking about.
Thanks in advance!
