The mouse works perfectly, but the dongle does not. Sometime I walk away from pc for a few minutes (around 10 minutes), and then  when I come back, the dongle LEDs are turned off, I tried to move mouse to activate the dongle but it clearly doesn’t work, but somehow when I click the mouse buttons, the LED that indicates “connection quality” blinks, the other two LEDs still don’t work. So every time  this happens, I need to unplug and re-plug the dongle to make it work, which is annoy since this is a $160 mouse. Is this dongle defect?

I tried some other methods in other threads, like connecting the dongle to motherboard directly, it doesn’t work.

I am having the same issue. I’ve tried:

  • Pressing every button on the mouse (LMB, RMB, scrolling up/down, clicking scroll wheel, side buttons, power/dpi on the bottom)
  • Wiggling the mouse
  • Using the PC without the mouse (alt+tabbing into a browser, windows key, playing a youtube video)

Opening Synapse Web when this happens says the mouse is sleeping. Bumping for visibility

I encountered the same problem twice. I long pressed the bottom power button to turn off the mouse, and then long pressed it again to turn it back on, which worked normally
