Abstract
An external storage device includes a power management system. The power management system comprises an energy storage circuit which stores energy from a power source and provides additional power to the external storage device. The external storage device further comprises a microcontroller which determines whether the combined power from the power source and the energy storage circuit is sufficient for the external storage device to perform a particular command received from a host computer. If the power from the power source and the energy storage circuit is insufficient, the microcontroller causes the external storage device to either suspend the command until sufficient energy is stored on the energy storage circuit to execute the command or execute the command at a rate slower than a normal rate.
