A device and method for making a peripheral device compliant with a power management standard, such as the USB standard, are described. The device includes a power management unit (PMU) and a timing unit. The PMU is coupled to a battery pack and to a processor of the peripheral device, and manages power allocated to the processor. The timing unit sends electrical signals to the input terminals of the PMU when the battery pack is connected to the peripheral device. The electrical signals activate the processor via the PMU. The timing unit sends the electrical signals before a configurable time from the time when the battery pack is connected to the peripheral device.
