First Claim
1. An electrical system, comprising:
- an electronic device comprising;
an external power port configured to receive external power from an external power source that is external to the electronic device, the external power sufficient to support normal power requirements of the electronic device operating in a normal mode; and
control circuitry coupled to the external power port and configured to receive sensor inputs from one or more sensors configured to detect events associated with a future disconnect of the external power port from the external power source prior to the future disconnect of the external power port from the external power source, the control circuitry programmed to;
operate in the normal mode while the external power port is receiving the external power; and
transition to one of a low power mode and a pre-shutdown mode responsive to the sensor inputs;
wherein the one or more sensors comprise at least one sensor selected from the group consisting of a proximity sensor, a capacitive touch sensor, an infrared sensor, an optical sensor, an accelerometer, or a motion sensor.

Abstract
Disclosed are electrical systems and electronic devices. An electrical system includes an electronic device. The electronic device is configured to receive external power from an external power source, the external power sufficient to support normal mode operation of the electronic device. The electronic device includes control circuitry programmed to operate in the normal mode while receiving external power, and transition to one of a low power mode and a pre-shutdown mode responsive to sensor inputs. An electronic device includes an internal power source configured to provide internal power sufficient to support low power requirements of the electronic device operating in a low power mode, but not sufficient to support normal power requirements of a normal mode. The electronic device includes control circuitry programmed to transition from the low power mode to a hibernate mode while powered by only the internal power source.
