2 days ago I left the beam connected to the steam deck and glasses and it must have run out. I tried a strong PD charger, resetting it for 15 seconds and leaving it connected to the glasses for some time. Nothing helped, it is still dead in the water.
Would be thankfull for any suggestions.
After the 15-second reset, please disconnect the glass from the Beam. Then, use a charger with an output higher than 5V/1A to charge the Beam.
