Logitech Wonderboom 1 Blinking White Light: During Charging
The Power lamp blinks white while the Logitech Wonderboom 1 is recharging.
This light blinks in a gradually dimming and brightening pattern. On this speaker, this LED is the only visual indication that charging is happening. But it does not tell how far along the charging is.
It blinks during charging whether the Logitech Wonderboom 1 is OFF or ON.
As charging continues, the light keeps slowly blinking white. Furthermore, battery recharging is over when the lamp goes out, or turns solid white. It turns OFF when the speaker is OFF, and switches to a solid white glow when the speaker is ON.
The battery recharge cycle finishes when the speaker status lamp turns OFF. Even with the AC charger running, the lamp does not glow when battery is full. Not unless the speaker itself is running.
