How can I test every USB-C function available on my laptop?

I need a comprehensive method to test all USB-C capabilities on my laptop, including data transfer speeds, video output, power delivery, and Alt Mode functionality for external displays and accessories. I am looking for a systematic approach using free tools or built-in system utilities to verify that every port is fully operational and supports all advertised features.

    Look up your laptop's exact model on the manufacturer's website to find the official specifications for its USB-C ports. Not all USB-C ports are the same; some are only for data, while others support video or charging.

    Before testing, ensure your system is up to date. Update your BIOS, Windows packages, and drivers to the latest versions, as software updates often improve system stability and USB-C performance.
