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.
