Not exactly sure what you mean by hard reset. The hardware level resets are SMC and PRAM (NVRAM) resets.

SMC Reset (follow directions for your model): https://support.apple.com/en-us/HT201295
PRAM Reset: https://support.apple.com/en-us/HT204063

If your MacBook is stuck on something then holding the power button for 10 or so seconds will shut it down so you can restart it. Maybe this is what you are asking?
