The magnets in the corners of the rear LCD bezel allow the display to snap into place for either netbook or tablet usage.

The offset magnets are used to tell the computer what orientation the LCD is in (tablet or Netbook). Remember these?

The switches on the underside of the upper case are Field-Effect Transistors (FET), which alter their conductivity in the presence of a magnetic field. The offset magnets in the rear bezel cause the FETs to indicate which position the screen is in.

Apparently we are not supposed to touch the inverter board. This is likely due to the frailty of the connections between the board and the LCD cables.
