For power saving, a structure of a capacitive touchpad comprises a soft board having a bottom surface with a first conductor thereon, a printed circuit board having a top surface with a second conductor thereon, a flexible insulator between the soft board and printed circuit board, and a control circuit having an I/O port connected to the second conductor, such that a pressing on the soft board may move the first conductor down to contact the second conductor to thereby generate a voltage change signal present on the I/O port, causing the control circuit to wake up the capacitive touchpad.
