I know it all may seem weird, but the problem was the nvmie SSD. And you know when i found it? When i packed it back, to return it. I would be interested to know if disabling your discrete graphics via device manager resolves your issue too? I've learned to live with it but find it unacceptable in a premium flagship laptop. Over many months I've tried re-installing drivers, resetting power management and have updated windows without success. Running software to analyse the dump files highlights the Nvidia display drivers as the cause and a power state fail linked to the windows desktop manager. This completely resolves the problem and I get no more driver state power fail issues. I have a work around by going into device manager and disabling the discrete GTX1050 graphics card when on battery power and re-enabling when on mains adapter - only takes a few seconds. Have contacted Dell, Microsoft and Nvidia and no one has been able to solve the problem. I've had a similar problem with my 9560 for over a year except that its Ok on mains power but with the discrete graphics card enabled I get the driver state power fail when running on battery after about 10 mins of use and often when switching apps etc. This is the memory dump file if it helps. like every 10 minutes? especially when i try changing something, or whatever. I have tried doing also a clean install directly from windows (windows media creation soft). Googling, suggested disabling sleep mode for various devices, so i have set them to maximum performance. Yes, i have downloaded all drivers from official dell site no fix, i did clean install by DELL recovery USB stick, and then also tried downloading drivers from manufactures directly (for example NVIDIA has newest drivers than DELL for GPU, so has intel for the intergraded HD630 graphics). New laptop for me (manufacture refurbished). This workround works fine, with minimal effect on my laptop usage. The problem was at it seems, that not all devices could report that they had "woken up" from sleep. ![]() ![]() It only takes a couple of seconds longer to reboot or to hibernate, but i've never had this problem again. So when i closed the lid, i choosed to hibernate (basically doing a proper shut down, while keeping the memory on a page file). What worked is completely disabling any sleep state of the laptop. Update : FIXED IT 2 years later, newer firmwares / drivers etc didnt do anything.
