Razer mice disconnecting problem

So I have 2 razer mice (razer orochi v2)(Razer viper mini) and they both have a disconnecting issue and now my razer orochi will turn on for a second when the usb is connected and i have tried several times to change the usb port and change the battery :( I seriously have no idea what to do with these mice. I used to main the razer orochi for a year and I loved it and now it just wont turn on at all. Someone please help me :)
