An integrated circuit such as a SoC may indicate the critical battery status without powering-on a substantial portion including the host processing cores. The SoC may include a microcontroller, which may cause the critical battery status data to be stored in a static memory and the display unit may retrieve such data from the static memory to display a visual symbol on the screen. The other portions of the SoC such as the dynamic memory, system agent, media processors, and memory controller hubs may be powered-down while the critical battery status is displayed in the visual form on the screen.

Methods and apparatus relating to controlling the supply of power to computing devices with dynamically variable energy capacity are described. In one embodiment, logic causes modification to supply of power from a power source to one or more loads in response to a comparison of an output of the power source and a threshold value. The output of the power source may vary over a time period (e.g., oscillating) that causes the one or more loads to become inoperational. Other embodiments are also disclosed and claimed.

In a case where a plurality of users share the use of one mobile terminal, an image forming apparatus has performed authentication printing also on image data to which the previous owner of the mobile terminal has sent a printing instruction. According to the present embodiment, an image forming apparatus includes a data reception unit configured to receive data having a device ID of a mobile terminal and user information for identifying a user of the mobile terminal, and includes an authentication information reception unit configured to receive authentication information including the device ID and the user information from the mobile terminal. The image forming apparatus also includes a print control unit configured to control, in response to the reception of the authentication information, a printer to print the data received by the data reception unit.
