Synapse 4 Suddenly Not Detecting Razer 16 (2025)

Hey all, Synapse 4 was working perfectly fine until I decided to give it a refresh by closing it from the system tray. I relaunched it, it automatically updated, and now my laptop (Razer Blade 16 2025) is not being detected. It’s listed as ‘disconnected’ under connected devices.
I have uninstalled it, repaired it, performed a windows update, and rebooted my laptop multiple times to no avail. 
 

It seems like a random update to synapse caused this issue, since it was working perfectly fine until I restarted synapse. I use synapse for smart battery charging, etc, so I am kind of reliant on it working properly. 
 

Coming here to see if anyone else is experiencing this issue.

I have the same issue on my razer 18 2025. Just noticed it today. Was working in September.


Solved issue by uninstalling all Razer software from the Control panel.

Then I went into C:\Program Files (x86)\Razer and looked for any Uninstall bat scripts to uninstall any hidden razer software. Specifically, the Razer Services. I think uninstalling this is what did it.

Then when a ran Windows Update it found razer drivers to install which required a reboot. Possible this was just a new update that just got released.

Then ran the Razer Synapse 4 installer. Which finally detected my laptop.
