The most common indicators that your Mac has had an SMC reset are improved fan speed, brighter display brightness, or faster start-up times. Additionally, you can check the power indicator light on the front of your Mac. If it was orange prior to the reset and is now green, then this is a sign that your Mac has successfully performed an SMC reset.

The Effects of a PRAM Reset on a Mac

This will reset the PRAM, restoring settings like display resolution, speaker volume, startup disk selection, and other settings that are stored in NVRAM (nonvolatile RAM).
