Day two with Quest. Fantastic device but after using for a few hours while streaming (power was at 35%), found that the charge indicator would not come on. Tried different outlet, powering off/on, but it wasn't working.
Reading online, I found a similar issue with Oculus Go, where users had to hold a button combo to fix.
So, what I did that seemed to work: Held power button and (-) volume button simultaneously (device not plugged in when I did this). After about 5-10 seconds, I heard a beep and the indicator light blinked a few times (i guess indicating a reset?). In any case, I was able to charge again after and the light is on again when charging. So far so good on recharges.
Just throwing it out there in case this happens to anyone. Also submitted ticket to notify Oculus team. Cheers.
