Abstract: Example implementations relate to determining computing device information. In some examples, a controller may comprise a processing resource and a memory resource storing machine-readable instructions to receive a waveform corresponding to an input current that includes a non-cyclical irregular waveform modification from a power supply of a computing device, analyze the modified waveform of the input current to determine a binary message included in the modified waveform, and determine, based on the binary message, information about the computing device.

Abstract: Example implementations relate to determining computing device information. In some examples, a controller may comprise a processing resource and a memory resource storing machine-readable instructions to request a handshake signal from a power supply of a computing device, receive a response signal from the power supply that includes modified power factor correction characteristics in response to the handshake signal request, and determine, based on the modified power factor correction characteristics, information about the computing device.
