I have a Macbook A1181 (820-2279-A motherboard), which is probably this model: _everymac.com/systems/apple/macbook/specs/macbook-core-2-duo-2.1-white-13-early-2008-penryn-specs.html
It is essentially just the laptop bottom (no LCD).
How can I force this to boot to an external monitor?
I would appreciate people with personal experience doing this. Seems an almost unexplored pursuit.
I wish I was a competent electrical engineer.
I learned a bit about reed sensors/switches vs. hall-effect.
I'm not sure if my magnets are powerful enough. They are not terribly strong.
I don't even know if the hall-effect sensor tripping will force it to (from boot time) display only on the external monitor. Anyone confident in messing with this circuitry?

On page 3, you can see the pole configuration. I have the LH package (I am pretty sure). Any thoughts? Honestly, the chip only says:
This style hall-effect sensor seems to have a universal configuration? The configuration was the same with the 3 manufacturers I checked.
This kid "sort of" did what I am trying to do:

*What he is calling a reed switch is a hall-effect sensor; more info (for amateurs like me):

Sorry to ask such beginner-esque questions. I am slowly learning.
Thanks,
Jaime
