Abstract
A method to manage power to a device includes receiving a first power-off request signal, initiating a predetermined delay period, and canceling the first power-off request if a second power-off request signal is received before expiration of the predetermined delay period. If a second power-off request signal is not received before expiration of the predetermined delay period, a signal to cause the device to power down may be generated. A device to perform the method and a system including such a power control device are also described.
