Abstract
A computer system includes at least one device, a connector which is connected to a power supply apparatus which supplies power having a predetermined level to operate the computer system, a power unit which converts and provides the power supplied from the power supply apparatus to the at least one device, and a controller which analyzes a signal waveform of power supplied from the power supply apparatus and identifies information of the power supply apparatus carried by the signal waveform. Accordingly, an abnormal operation of the computer system can be prevented by transmitting power information such as a power capacity of the power supply apparatus to the computer system.
Claims30
A computer apparatus comprising:
- at least one device;
- a connector which is connected to a power supply apparatus that supplies power having a predetermined level to operate the computer system;
