Abstract
Method and apparatus of controlling a power state of a computer, the computer being connected to a monitor having a power control button. The computer is connected to the monitor over a video cable, and activation of the power control button is communicated to the computer over a wire in the video cable. In response to the activation signal, a system management interrupt is generated to invoke an SMI handler to change the power state of the computer. The power states of the computer include an ON state, an intermediate power state (such as Sleep state), and a suspend state (such as Soft-Off state).
