The NVIDIA Away Mode System driver is related to a feature designed to optimize the power management of NVIDIA graphics cards, particularly in scenarios where the system enters a low-power state (like sleep or standby) but still needs to perform background tasks or media streaming. It's mostly seen in some desktop systems with NVIDIA GPUs, and its purpose is to ensure that the GPU remains in an efficient, low-power mode while not completely shutting off when the system is not in active use.

The Away Mode itself refers to a power-saving state that allows the computer to continue certain background activities even when you're not actively using it, such as streaming media, downloading, or running specific background applications.

However, this feature is typically found in systems using specific hardware configurations or custom OEM implementations, so it's not something that would usually be installed or activated manually by the average user unless it's part of a custom build or setup.
