Abstract
A HDD backboard includes a power detecting circuit and a first working circuit. The power detecting circuit is configured to determine whether a plurality of voltage rails of the HDD backboard are normal, so as to output a power detecting signal. The first working circuit is coupled with the power detecting circuit and configured to receive the power detecting signal and output an HDD backboard determining signal. The motherboard includes a second working circuit and a CPLD. The CPLD is configured to receive the HDD backboard determining signal The CPLD is configured to determine whether the HDD backboard is absent when the electronic device operates in a standby mode and determine whether the voltage rails are failed when the electronic device operates in a working mode.
