The lid is sensed by a magnetic switch which would be situated on the motherboard and is something that should not really be messed with. It is disabled in the power options of the O/S.

Hope that enlightens you and enables you to have the laptop how you want it.

By connecting an external keyboard, mouse, and monitor, a laptop can function like a desktop. ... By default, Windows puts your laptop to sleep when you close the lid. This means that even if you don't want to use your laptop screen as a secondary monitor, you still have to keep it open to keep your computer awake.
