What needs to be done when Samsung S7 doesn't respond to hard restart?

[Android Central Question]

I did hard reset on my Samsung S7. I cleared cache partition then rebooted it. It turned up ok and I left it plugged to my laptop. I checked to see that it had 3GB free space. It was also charging at around 80%. When I came back after 15 minutes, the screen was solid black with glowing red light. It doesn't respond to hard restart anymore.

Why did you do the hard reset?

Welcome to Android Central! Let it sit on a wall charger for at least 6 hours undisturbed. Then press and hold Power and Vol Down for 20 seconds to force a shutdown, just in case the phone is frozen on a blank screen. Then wait a few seconds, and press and hold Power for another 20 seconds to see if anything happens. If not, then the battery probably failed -- bring it to a repair shop.
