This is GNOME power manager utilities that work with the enhanced acpi (battery, lid, brightness, power button) and CPUfreq scaling.
The GPM GUI was integrated in nevada build 92.
GNOME Power Manager (GPM) is a set of utilities for the desktop user to manage everything about power in his laptop or desktop system. GPM stems from GNOME community. Now we port it to Solaris.
It supports following features:
o Monitor battery status, which shows whether battery is present or not and alerts when battery power is critically low.
o Trigger an action when lid is closed.
o Set CPU frequency policy.
o Set power button response action
o Adjust laptop screen brightness.
o suspend/hibernate system.
o Visualize power consumption statistics.
NOTE: Suspend on laptop is an experimental feature so far.
