Power-on pads on logic board
With the top case removed, the power-on button is disconnected. Instead of having to reconnect the top case to turn on the system, there are two pads on the logic board when shorted together (with a tool like the head of a flat blade screwdriver) is the equivalent to pushing the power-on button.
These pads are located near the edge of the logic board, just above center of the hard drive. It is marked POWER BUTTON. The pads are separated with a vertical white line.
