    Hey guys,
    I must say I have always been a browser of this forum for over a year but never really found the need to register and post up. Well now I am...
    Recently I have been building a custom Powerbook G4 1.5GHz 12" tablet. I have all the parts and everything is coming along nicely. The only problem is that because of the tablet form, the lid will technically be closed on the powerbook with the magnetic latch locked in while the screen is flipped around to display through my custom cut top.

    My question is, what exactly senses that the lid is closed and puts the powerbook in sleep mode (eg magnetic latch, something in the hinge..)? How can I disable that so that it always thinks it's open? Is there an app I can install to make sure it never thinks it is closed?

    I tried googling the issue and found absolutely nothing. I have seen a few macbook/powerbook tablets so I know it can be done.
    Any help would be great as it is an outcome for university and it is due-in next week!

    Thank you for the reply 666sheep! Very helpful indeed.
    Would you happen to know if the Powerbook would run with no problems if I simply unplugged and removed the hall effect sensor instead?
    Currently my Powerbook is in 100s of pieces and I won't be putting it back together again until it is all finished; any help would be great!

    Thank you.

    There's a second, smaller magnet, on one side of the bezel behind the lcd's frame. There are also 2 magnets that act as latches, which do not put it into sleep mode.

    on the ibook its the one in the bezel on the right side about in the middle , so i suppose its the same in the powerbook responsible for sleeping or not
