I have exactly the same issue. Got the Controller and all it does is vibrating once, showing white light once. Nothing else.
When I put it on the charger it vibrates once and blinks orange once. Tried all tips i could find online.
This thing is dead...
You could contact Google support but sure to try a hard reset and a factory reset.

Did you setup the controller with the Stadia app? This could send a update to the device.
If that doesn't work go to following website:
https://support.google.com/stadia/gethelp
Search for Stadia controller broken (example)
Don't tap or click on any suggestion but choose next.
Now you can choose to chat with a support agent to get your controller replaced (within the warranty period).
