Abstract
A motherboard includes a central processing unit (CPU), a drive, and a voltage-state display system to display a voltage mode of the CPU. The voltage-state display system includes a power management chip, a first transistor, a second transistor, a first light emitting diode (LED), and a second LED. A first phase output terminal of the power management chip is connected to the first LED through the first transistor. A second phase output terminal of the power management chip is connected to the second LED through the second transistor. The LEDs indicate the voltage mode of the CPU.
