Method for saving the data based on power source

The invention, suspend mode relates to a way to save the system state data in accordance with a remaining capacity of the battery to the server via the local memory instead of the Internet communication network, the suspend mode when switching, the current system state (Status) of data to the local memory and stored in a first step to continue to check the battery remaining capacity; When the check of battery residual capacity than the reference value, a second step of storing and transmitting to a backup server for the data stored in the local memory via the data communication network; And made up by a third step of returning to, suspend mode when the data storage completion to the server, to keep track of, the battery remaining amount when the suspend mode, if the remaining battery power is not low on is shown the state of the system immediately before the suspend mode data by the read from local memory stored on the server over the Internet, even if the system is suddenly down due to battery discharge it will be very useful inventions no fear of losing important data.
