This article provides troubleshooting steps for when the Razer Core is not recognized by the Razer Blade.

 

One of the possible causes of this issue is the USB selective suspend setting on your Razer Blade. The USB selective suspend setting enables the hub driver to temporarily stop the operation of a specific port in the hub without affecting the performance of the other ports or the operation of the whole system. This feature allows the laptop to save battery and extends the operation of your device.

There are several ways to resolve this issue. One of them is to disable the USB selective suspend setting on your Razer Blade laptop.

  1. Go to the "Control Panel" > “Hardware and Sound.”

    Hardware and Sound in the Control Panel

  2. Click “Power Options".

    Power Options under hardware

  3. Click “Change plan settings".

  4. Click “Change advanced power settings".

  5. Click the “+” icon on USB settings.

    Expand USB settings

  6. Click the “+” icon on the USB selective suspend setting.

    Expand USB selective suspend setting

  7. Click the drop-down arrow and choose “Disabled” on either “On battery” or “Plugged in,” or both, depending on your plan settings.

    Choose disabled in on battery or when plugged in

  8. Click “Apply,” then click “OK.”

    Click apply button before clicking OK
