An exemplary computer motherboard of a computer includes a basic input output system (BIOS) chip having a detecting module, a plurality of function elements, and a control chip connected to the BIOS chip. The control chip includes a plurality of detecting pins each corresponding to a corresponding one of the plurality of function elements. Each of the plurality of detecting pins is grounded via a switch. Each of the plurality of detecting pins is connected to a power source via a resistor. The detecting module of the BIOS chip is configured for detecting voltage levels of the plurality of detecting pins of the control chip, and controlling power states of the plurality of function elements according to the voltage levels of the plurality of detecting pins of the control chip.
