I have a W10 VM that often refuses to resume cleanly after being suspended. Windows throws the error Driver Power State Failure and then reboots (eventually). This has been happening for a few weeks. Can any one shed any light on what is causing this? Win10 Pro running under Parrallels Pro Desktop 15.1.3 on iMac (late 2014) Catalina 10.15.3.
@JonR3 Hi, driver Power State Failure is a BSoD error and it shows up mostly as a result of an incompatible driver installed. It might be solved with a simple restart but if not, Please go to device manager > choose Parallels Display driver > right click driver > uninstall and reinstall Parallels tools by referring this KB article https://kb.parallels.com/115835 Also, execute this command sfc /scannow on Windows powershell admin to scan and repair the system.
