Use a microfiber cloth dampened with distilled water or a screen-cleaning solution. Gently wipe the screen in circular motions, avoiding excessive pressure.
Visit the ASUS support website and download the latest BIOS update for your model. Follow the provided instructions carefully to apply the update.
Ensure the vents are not blocked and clean them if dusty. Use the laptop on a hard surface to allow proper airflow. Consider using a cooling pad for additional cooling.
Reduce screen brightness, disable unused hardware like Bluetooth, close unnecessary programs, and use power-saving modes available in your operating system.
