The function keys on my keyboard, cynosa chroma, don't work. When I press the “fn” key to access secondary functions of the F1-F12 keys, the secondary “fn” operations don’t work. The F1-F12 key row lights up when I press the “fn” button, but they do nothing when I then press one of the F# keys while holding down the “fn” button. I specifically want this to work for volume up/down, but none of the F keys work in this fashion.
I am running:
- Razer Cynosa Chroma keyboard
- Razer Synapse version 3.10.315.31117 (20250324 version, no newer versions available)
- Windows 11 Home, 24H2 update
- No key customizations or game profiles in the Synapse program; I only use the Synapse program to adjust the lighting of the keyboard
What I have tried:
- Different USB ports--NO EFFECT
- Reset keyboard in the Synapse program--NO EFFECT
- Uninstalling the Synapse program and deleting the Razer folder. Rebooting windows and reinstalling the Synapse program--NO EFFECT; as long as the Synapse program is running and I am singed into the Synapse program, the fn+F# secondary operations DO NOT work.
- Closing the Synapse program--This ALLOWS the fn+F# secondary operations to work.
- Logging out of my profile in the Synapse program and using as “guest” but keeping the program open--NO EFFECT
While closing the synapse program does allow the fn+F# operations to work, this is not a solution since I cannot adjust the keyboard lighting. I don’t understand why this won’t work as soon as I am signed into the synapse program.
