Delayed shut down of a computer

A computer-implemented activity control system in a computing device, the system comprising:

• at least one sensor arranged to identify an indication that the computing device be shutdown, the shutdown transitioning the computing device from an active operating mode to an inactive operating mode;
• a shutdown timer responsive to the identified indication that the computing device be shutdown, the shutdown timer being programmed to:
• access data for computing a shutdown delay period for a shutdown of the computing device, the data being based on an observed state of the computing device;
• compute the shutdown delay period based on the accessed data;
• adjust the shutdown delay period based on an identified battery level;
• wait the adjusted shutdown delay period;
• and
• provide an indication of an expiration of the adjusted shutdown delay period;
• and
• a computer activity manager being programmed to:
• receive the indication of the expiration of the adjusted shutdown delay period;
• and
• in response to receiving the indication of the expiration of the adjusted shutdown delay period, transition the computing device from the active operating mode to the inactive operating mode.

A non-transitory recordable storage medium having recorded and stored thereon instructions that, when executed by a computing device, cause the computing device to perform actions of:

• receiving, by the computing device, an indication that the computing device be shutdown, the shutdown transitioning the computing device from an active operating mode to an inactive operating mode;
• based on receiving the indication that the computing device be shutdown:
• observing a state of the computing device;
• and
• identifying a battery level;
• determining that the shutdown of the computing device be delayed based on the observed state of the computing device;
• computing a time period to delay the shutdown of the computing device based on the observed state of the computing device;
• adjusting the time period to delay the shutdown of the computing device based on the identified battery level;
• setting a shutdown timer equal to the adjusted time period;
• starting the shutdown timer;
• waiting the adjusted time period as established by the shutdown timer;
• determining from the shutdown timer that the computing device be shutdown;
• and
• based on determining that the computing device be shutdown, transitioning the computing device from the active operating mode to the inactive operating mode.
