T-BEAM T22 _V1.0 dead after running out of battery

[A Former User]

Hi,
I wanted to determine how long the T-BEAM can run from a charged 18650.
Battery level was 4% in the evening, so I expected it to be off in the morning. However, now the T-BEAM seems to be dead, i.e. it does not power-up or charge when USB is connected.
Windows recognizes the USB port when connecting, but the ESP obviously doesn't do anything then (no connection, no application running, no LED switched ON, etc.).

Has anyone experienced the same and found out a way to bring it back to life?

Thanks, Thomas
