Abstract: An electronic device comprises a wireless unit, a control unit starting up the wireless unit at a predetermined startup time and a storage unit, wherein the wireless unit queries a wireless base station about a message and, when the message addressed to the electronic device exists, receives the message from the wireless base station, the control unit, when the message received by the wireless unit is an erase message, executes a process of erasing data stored in the storage unit, and the control unit, whereas when the message received by the wireless unit is not the erase message or when there is not the message addressed to the electronic device, stops the wireless unit.

Abstract: A control apparatus controls a supply of power to a second apparatus that operates independently of a first apparatus, and includes a notifying part to make a notification that notifies a need to control the power supplied to the second apparatus if needed, based on a preset timer time and a present time acquired from a Real Time Clock (RTC) within the first apparatus, and a supplying part to supply information related to a time for controlling the power supplied to the second apparatus, based on the notification from the notifying part, wherein the notifying part and the supplying part are operable with a power that makes only limited functions within the first apparatus operable.

Abstract: When a prescribed application such as a TV application, etc., is activated by using a general-purpose OS, an application activation device can inform a user of the fact that it is now in preparation for activation of the application, so as to avoid inducing the user to become uneasy during his or her waiting. The device includes an activation event input section (1) for inputting an activation event for the TV application in either of plural power supply states of a computer when the TV application is activated from either of a power off state, a hibernation state and a standby state of the computer, an activation event detection section (2) for detecting an input activation event, and an activation preparation state indicating section (3A) for indicating, during the time from when an activation event has been detected until when the TV application is activated, that the TV application is in preparation for being activated.
