Hi, I got an SP4 i7 8GB 2 weeks ago. So far it's great and I've set everything up to use it for music production, except one problem... I've been trying to access High Performance power mode (very important for stable low latency audio while doing music), mostly by following guides like this: Unauthorized link removed but I cannot get it to work?! The only option I have is Balanced and even turning on Hyper-V doesn't change this? Doing a "powercfg /a" in the the command prompt gives me the same readout with Hyper-V installed or uninstalled. Anyone else having the same problem or found a work around? I've even done a complete clean re-install using the Win10 Media Creation Tool. Nothing has worked.
