The Asus sensor board plays a critical role in your laptop's performance by collecting and transmitting data from internal sensors. These include temperature sensors, ambient light detectors, and battery level modules. If you're facing issues like a fan that never slows down, screen brightness that won’t adjust, or incorrect battery percentages, your internal sensor controller board may be malfunctioning.
Common symptoms include constant high fan speed, ambient light sensor failure, inaccurate CPU temperature readings, or battery drain misreporting. Instead of replacing the fan or motherboard, installing a new sensor board is often the correct and more affordable solution.
