I think I may have the solution to your problem. I had the same issue so I contacted one of the dell support members and they deleted MY DELL app because that was what was preventing the power manager from opening. After uninstalling the My Dell app you can now download the power manager app from the Microsoft store. We can also Dell Power Manager Service on the XPS 13 9310 driver page =[IMAGE]
Is anyone else having the same issue with there XPS 13 9310? DPM (Dell Power Manager) is no longer available, can not access it from My Dell, it just send me to the Windows Store to download Power Manager, which wont install fully because it tells me to access it at myDell, where its no longer available, if tried re-installing and it hasnt work, also tried the 30 march 2021 Dell Power Manager Service update but this has the same effect, just send me back to myDell where it is unavailable. Because of this i no longer have access to my thermal setting to control the fan. Does anyone have the same issue or any help.. thank you
