General Information
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 about 5cm left of the back left corner of the optical drive, 1-1/2cm
above the notch for the top case flex cable. It is marked POWER BUTTON. The pads are
separated with a vertical white line.
