Power Management
3 - 6 Power Plans

An additional power plan will be available when you switch the computer to UMA
Mode (for constant power-saving with the integrated GPU only). As UMA mode is
usually used to save the maximum amount of power through the integrated graphics
system, the UMA Mode power plan’s standard settings are also configured to save
the maximum amount of power if selected.
When the system is switched to Optimus mode, the UMA Mode power plan will
return to Balanced.
