摘要

PROBLEM TO BE SOLVED: To provide the system, activity recording information handing-aver method electronic equipment, electronic equipment control method, and storage medium which contains past activity recording information of respective devices whichever device is disconnected, reduces the power demand by placing devices having less activities in the past in power-saving mode even in the case of a deficiency in demanded power, and enables the electric power to be used efficiently. SOLUTION: Respective devices A21 to F26 are able to function as a host machine or sub-host machine and respective devices A21 to F26 have storage parts 211 and 262 which store activity recording information on respective devices connected to the system and control parts 211 to 262 which alter the activity recording information in the storage part when the system constitution is altered.
