Understanding the Issue: Why Does the B550-F RGB Logo Stay On?

To effectively address the issue of the B550-F RGB logo remaining illuminated after shutdown, it is crucial to understand the underlying causes. The primary reason this occurs is related to the motherboard's power delivery settings, specifically the ErP (Energy-related Products) setting and the USB power delivery in S5 state. Modern motherboards, including the ASUS ROG Strix B550-F Gaming, are designed to provide power to USB ports even when the system is turned off. This feature is intended to allow devices like smartphones and other USB-powered gadgets to charge while the PC is not running. However, this continuous power supply can also affect the RGB lighting on the motherboard, causing it to remain active.

The ErP setting in the BIOS plays a significant role in managing power consumption in sleep (S3) and off (S5) states. When ErP is disabled or set to a lower setting, the motherboard continues to supply power to certain components, including the RGB LEDs. This is because the system is technically in a low-power state rather than a complete power-off state. Additionally, the USB power delivery in S5 state setting determines whether USB ports receive power when the system is shut down. If this setting is enabled, the motherboard will continue to provide power to USB devices, which can inadvertently keep the RGB logo illuminated.

Another factor to consider is the software control of RGB lighting. ASUS's Aura Sync software, or similar RGB control software, may have settings that override the default power-off behavior. If the software is configured to keep the RGB lighting on, it will do so regardless of the system's power state. Therefore, understanding these interactions between BIOS settings, hardware configurations, and software controls is essential to accurately diagnose and resolve the RGB logo issue on your B550-F motherboard.
