This answer explains why the F1 to F12 function keys do not light up when pressing the "fn" key.

This feature works with the Razer Blade models that have Per key RGB Powered by Razer Chroma™ anti-ghosting backlit keyboard.

Check your product specifications to see if your Razer Blade has this feature.

  1. Go to your model's support page in Razer Laptop Support.

  2. Select your Razer Blade model.

  3. Click "Specifications".

  4. Confirm that the "Keyboard" shows "Per key RGB Powered by Razer Chroma™ anti-ghosting backlit keyboard".
