Method of controlling network system

摘要

Monitoring a connection with a network system by informing a monitoring computer working with another computer on the network of a predictable network disconnection event. For example, when employing a battery as a power source to the other computer, a remaining battery power of the battery is detected and power information based on the detected remaining battery power is transmitted to the monitoring computer. The monitoring computer indicates the received power information, thereby allowing the monitoring computer to prepare against such sudden predictable network disconnection.
