Energy Star

The Energy Star® program, a government-backed initiative, promotes energy efficiency by identifying
ways to reduce energy consumption. Select HP workstations participate in the Energy Star program.
NOTE: Energy Star is not supported on Linux-based workstations.
For those workstations that support Energy Star and have it enabled, the power management features
are set as follows:
