Glowing Green is ON period?
No now white device light stays on period.
This things battery will never last. That light will drain battery.
Even when not connected over bluetooth or Logitech dongle.
Wait on vermeer this is NOT happening?
White # blinks when not connected.
Does not indicate battery level in Windows.
Died within one week of full charge (cuz green light never goes out)

when the LED is:
Glowing green — Up to 100% battery life
Glowing red — 10% charge remaining
blinking green - charging.
plug the provided Unifying receiver into a USB port, use an existing Unifying receiver, or connect with Bluetooth.
Has 2 Device switch on top.
The bluetooth range with antennas on Ryzen is great.
Way better than unifying receiver and old logitech mouse.
