Abstract: According to one embodiment, an electronic apparatus includes a first determination controller, a second determination controller and a security controller. The first determination controller determines, at intervals of a first time period, whether or not communication with a management server is executable. The second determination controller determines, when it is determined that the communication with the management server is not executable, whether or not a second time period elapses from a last one of times at each of which it is determined that the communication with the management server is executable. The security controller executes a process for inhibiting use of the apparatus when it is determined that the second time period elapses.

Abstract: According to one embodiment, an information processor capable of supplying power to an external device includes a connector, a storage module, a receiver, a selector, and a power supply controller. The connector connects the external device to the information processor. The storage module stores identification information that identifies the external device and a power supply mode in association with each other. The power supply mode defines a condition of each element of the information processor to cause the external device to be chargeable. The receiver receives the identification information from the external device connected to the information processor. The selector selects the power supply mode stored in the storage module in association with the identification information. The power supply controller sets the element of the information processor according to the condition defined by the power supply mode.
