Auto refresh for data from on-premise SharePoint

Hi guys, 

I have connected data from on-premise SharePoint to PowerBI and set up scheduled refresh. However, i need to add a gateway and make sure my computer is not shut down for the scheduled refresh to work. Else it will fail. 

Do you guys know of any work around that i do not have to leave my computer on, and still be able to have the scheduled refresh work?

Thanks all!
