The ALi 7101 Power Management Controller is a hardware component typically found in older motherboards, particularly in systems based on ALi (Acer Labs Inc.) chipsets. The power management controller is responsible for managing power-saving features of the system, such as controlling power states, thermal management, and reducing power consumption when the system is idle. It helps ensure that the system is energy-efficient by enabling or disabling components based on usage.

The ALi 7101 driver is a software package that allows Windows to properly communicate with and manage the power management functions of this hardware component.
