CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based upon and claims the benefit of priority from Japanese Patent Application No. 2019-005048, filed Jan. 16, 2019, the entire contents of which are incorporated herein by reference.

FIELD

Embodiments described herein relate generally to a control device, an image forming apparatus, and a start-up method thereof.

BACKGROUND

In an apparatus such as an image forming apparatus, it is effective to power off the apparatus in order to reduce power consumption. Often times, when an apparatus in a power-off state is turned on, the apparatus is not ready to be used immediately. The apparatus requires a start-up time to boot up and to enter an operational state.

To reduce the start-up time, a method called hibernation can be used. Hibernation is a method of storing the contents of a main memory in a state where an apparatus is in operation as a hibernation image and loading the hibernation image to the main memory during the start-up of the apparatus. However, a start-up of an apparatus loading the hibernation image would fail or cannot perform when the apparatus is connected to different devices or systems compared to the connections (“connection state”) that have been saved in the hibernation image.
