There is an internal display switch in the lid (see link ) which turns off the display when the lid is closed. I think there is a magnet in the body of the laptop where the switch sits above when the lid is closed, to operate the switch.

The link is for the whole service manual ( I've just selected 1 page).

Hopefully this is of some help
