Okay, so here's the thing, if you have autoRCM and your switch dies, plug it into the wall directly with the power cable that came with your switch, and wait 45 minutes to an hour. No you will not see a charging indicator nor any LED lights or signs of life during this process. Wait 45 minutes to an hour and then unplug the switch from power, plug the dongle in, and press the power button.
If you don't see life right away try holding the power button for 15 seconds and then press the power button again. If you do not see the payload deploy, plug the switch back into the wall and let it sit for 3 hours and repeat the process. If you still don't see life, deploy a payload from your computer or phone to rule out a defective dongle. If you STILL do not see signs of life, you may be one of the VERY RARE unlucky few that need to hard reset the battery by disconnecting it, and re-attaching before charging.
Once you are in Horizon (Switch OS) immediately plug your switch back in and let it charge normally. This really isn't that hard of a concept to grasp. If you don't know what RCM mode does, then please educate yourself first before installing AutoRCM, or don't use it all. In nearly 99% of the cases, people believing their switch is bricked from AutoRCM + Battery dying are simply not charging their battery long enough, or giving up the moment they do not see the charging indicators / backlight come on. Those same people end up finding out later it was user error and almost always report back their switch is working correctly.
I've debunked that AutoRCM battery brick thread that was circulating misinformation countless times after proving charging works from a completely dead battery. Please follow what I outlined above and actually implement patience and critical troubleshooting before posting: "MY SWITCH WON'T TURN ON". That only serves to spread further misinformation.

TLDR; Your switch is NOT bricked, you only think it is because you are not patient enough
