(sorry for my english, im not a nativ) bought a new blackwidow elite 2 days ago, after games or waking up out of sleep mode, my keyboard is connecting and disconnecting over and over and over, the only solution every time is to use the small time-window between the reconnects to get to the profile manager in synapse an make an new empty profile and delete the actual profile ... this is really annoying! But sometimes this is also not working, so I have to kill all the Synpse-parts in the taskmanager, unplug an replug the keyboard and restart windows. I already tried the solution in this thread, nothing changes this behavior ... Without synapse 3, I dont have this problem. I really like the keyboard but if the software isnt working I have to give the Keyboard back to the reseller... cause its not working ! (and going to buy a corsair). So can you PLS fix your software razer? cause the keyboard is great but it's useless, when the software isnt working! thank you

edit: it also happens reproducible when my screen turned off and on again

I found out what i causes this behaviour in my case, if I activate the function that deactivates the keyboard led's automatically everytime when my display is turned off, then all this things that I described above will happen. If i turn it off or use the time function, everything is okay ...

I'm on Win 10 and have a similar issue. Keyboard dies all the time, never the mouse. Takes me 5-10 minutes of restarting, removing drivers and so until it pops up again... Really annoying!!!

So here are my new experiences:

  • Connected directly to my work notebook: Keyboard works
  • Connected to a USB switch to use the keyboard on multiple computers:
    If the switch is connected to the docking station, I experinece frequent disconnects
    If the switch is connected directly to the notebook, I experience rare disconnects
    If Synapse is not running, there are no disconnects
  • When I connect my mouse (A Corsair Scimitar Pro) to the keyboard, the disconnects increase
  • My Surface Book 2 and my Tower PC don't have any issues with the keyboard and the USB switch

So my conclusion, especially when having witnessed the increase of disconnects with the mouse connected: The keyboard draws a lot of power. My Surface Book 2 and Tower PC deliver enough power so the keyboard works, but my work notebook does not. When Synapse is not running and the Windows keyboard driver takes over, it uses a lower polling frequency which barely allows the keyboard to function without disconnects, but Synapse 3 does a lot more fancy stuff and stresses the USB a lot more which in turn causes the disconnects.

It's just what I suspect what is happening, maybe someone working at Razer can shed some light into this.

@Razer:
To reproduce this, use a Dell Latitude 5491 and the Dell WD15 USB-C Dock. Connect the keyboard to the dock, connect a mouse to the keyboard, run Razer Synapse and let it sit for a while. You will experience disconnects after a few minutes.
Then, connect the keyboard directly to the notebook, but do not attach a mouse, and let it sit for some minutes.
After that, add back the mouse and let it sit for some more minutes.
