Windows device driver information for Intel 82371AB Power Management Controller

The device driver for the Intel 82371AB Power Management Controller is associated with the process of activating and deactivating the power domains of the main processor. This particular hardware component is normally soldered onto the computer motherboard as a chipset and is activated with the installation of the device driver for the computer motherboard. The proper installation of the associated device driver allows the supported hardware component to correctly execute its intended function. The communication layer that exists between the main processor and the Intel 82371AB Power Management Controller may be implemented in the form of a memory mapped interface. This particular interface may be initially accessed by the computer processor before the memory module is instructed to retrieve it. For application specific computer processors the exact operation performed by the power management controller may not be expressed. It does however maintain its basic operation of placing the host computer system into shutdown or standby mode.

Outdated Drivers?

Unless you update your drivers regularly you may face hardware performance issues.

To check your drivers you should manually verify every device on your system for driver updates

The communication with the Intel 82371AB Power Management Controller is normally initiated by the software interface like the operating system platform. The instruction to put the processor into dormant or shutdown mode begins from this interface as activated by the computer user. Normally the device driver waits for the corresponding output to be inserted into the processor core before executing it. When entering the standby mode cuts the power to the main processor but allows the Random Access Memory modules to continue to receive input data. The data may be an instruction to bring the computer system out of the standby mode and passes this information to the processor thereby resuming the supply of power. The action of the processor actually depends on the exact instruction sets that are passed to it. In this context the power management controller must explicitly define what type of mode is being invoked otherwise the computer system may be placed into standby mode when a shutdown is required and vice versa. It is highly recommended you run a free registry scan for and Intel 82371AB Power Management Controller errors before installing any driver updates.
