摘要： The detecting unit detects a disconnection of communications that have been established with a display apparatus. When the disconnection of the communications is detected, the message generating unit generates a confirmation message that confirms whether the communications should be reestablished. The transmitting unit transmits the confirmation message to the display apparatus. The receiving unit receives a reply message that indicates whether the communications should be reestablished from the display apparatus. The main power supply controlling unit shuts down the main power supply when the reply message indicates that the communications should not be reestablished, or when no reply message is received.

摘要： When a processor, which transits from a first mode that causes a guest operating system to operate to a second mode that causes a virtual machine monitor managing the guest operating system to operate, when previously set transition condition is satisfied, transits to the second mode, a determining unit determines a cause or the transition. When it is determined that an execution of a process related to a completion of writing the image information in an image storage unit on the guest operating system is the cause, a detecting unit detects an updated portion representing an unmatched portion of the image information between before and after writing.
