1. A method, comprising:
- receiving a power consumption signal indicating that a computer system is associated with a low-power mode;
defining an on-state of a light-emitting diode associated with a status of the computer system, the status being associated with something other than the low-power mode; and
determining a duty cycle of the light-emitting diode based at least in part on the power consumption signal, the duty cycle to reduce a power consumed by the light-emitting diode, wherein said determining the duty cycle varies at least one of an on-period and an off-period, for the on-state, of the light-emitting diode.

Abstract
According to some embodiments, systems and methods may be employed for receiving a power consumption signal. An on-state of a light-emitting diode may be defined. A duty cycle of the light-emitting diode may be determined based at least in part on the power consumption signal. The duty cycle may reduce a power consumed by the light-emitting diode. The determination of the duty cycle may, for example, include varying at least one of an on time or an off time, for the on-state, of the light-emitting diode.
