Today my Librem 5 won’t turn on. When plugged in, I get a red light in the upper right hand corner for a few minutes, then nothing. Other than that, plugged or unplugged, there is zero sign of life. Anyone have any ideas here?

Maybe this: https://docs.puri.sm/Librem_5/Troubleshooting/Charging.html#evergreen Warning: I have linked to the procedure for Evergreen but I am only assuming that that is the batch that includes your phone. If not, scroll up in that page for earlier batches.
