Razer RZ09-0510x laptop fn key does not work. I have reinstalled synapse and run the Razer driver cleaner app. Issue still persists.

I have also tried to delay the synapse center start by setting it to automatic delayed.

i also tried disabling realtech drivers.

Hello marcusunlocked,

I understand that the Razer Blade 16” (2024) ‘ Fn key does not respond as expected. Do all Fn key combinations fail (brightness, volume, keyboard backlight, etc.), or only specific ones? Did this start after a Windows update, driver change, or Synapse update, or has it been like this since you got the laptop? Does the Fn key still not work if you restart the laptop and test it before opening any apps?

In the meantime, please go through the steps in this article, including checking and reinstalling the relevant drivers and software, to make sure nothing is missed. If the issue still persists after completing those steps, please send me a PM with the laptop’s serial number and your region so I can assist you further. All the best!
