What can I do about the lighting profile problem with the Razer Synapse?

1. Double-check your port.

A broken USB port might cause the razer synapse to not change lights in certain circumstances. If this is the case, disconnect your device from its current port and connect it to a different one.

It also doesn’t matter whether you connect your device to a USB 2.0 port rather than a USB 3.0 port, or vice versa.

If changing the ports doesn’t help, try inserting your Razer gear into a different port on a different computer.

If the lighting profile changes, the problem is with the device. To resolve this problem, contact Razer technical support.

2. Uninstall Razer Synapse and then reinstall it.

  1. Disconnect any Razer devices from your computer. Replace Razer devices with a conventional keyboard and mouse if you’re using a desktop.
  2. Uninstall Razer Synapse by going to Control Panel, Programs and Features, and then clicking Uninstall an application. Uninstall Razer Synapse if it appears in the list.Razer-Synapse-wont-change-lighting-Fix-it-in-3-steps
