Patent ID: 8432178

Claim:
A testing device configured for testing a board managing controller (BMC) of a computer motherboard comprising at least one power supply, at least one component, a board management controller (BMC), and at least one warning unit, the at least one power supply configured for powering a corresponding component, the BMC configured for monitoring whether the at least one power supply works properly and controlling the at least one warning unit to provide a warning according to the monitoring result, the testing device comprising at least one testing system corresponding to the at least one power supply, the at least one testing system comprising: a storing module storing a preset warning voltage and an upper limit voltage larger than the preset warning voltage; a voltage adjusting module adjusting the voltage of the at least one power supply of the computer motherboard; and a voltage displaying module displaying the output voltage of the voltage adjusting module; wherein wherein if the at least one warning unit does not provide warning when an output voltage of the voltage adjusting module is less than the preset warning voltage, or the at least one warning unit provides warning when the output voltage of the voltage adjusting module falls between the preset warning voltage and the upper limit voltage, indicates the BMC is working properly.
