If the problem did not occur under Windows 10, reinstall that (or uninstall 11 if you still have the option) and wait for a more stable release of Windows 11. 

Windows 11 is still very much a work in progress.  It took quite a while for Windows 10 to be stabilized, and the same applies to Windows 11.

Hello. Thank you for your reply. But is this really the solution? I think Dell should be aware of these kind of problems, especially since they claim xps is compatible with the new windows. If we pay for the top tier laptops, shouldn't we at least expect some support from their team to help avoid blue screen errors and to ensure that we can use the product?

I'm having the same exact issue here on an XPS 15 9570 on Windows 11, also. I had no issues for months on Windows 11 and it only recently started happening. Sometimes up to 1-2x per day. Hoping it's not a hardware issue.

Yes, it is now less convincing that it's a hardware issue. I really hope somebody from Dell will pay attention to his and provide the working fix. 

Hi ,

I recently upgraded my XPS 9570 to Windows 11 few days back. I am also facing the exact same issue. 
It never occured in the older Windows 10. 

Did you roll back to windows 10 because of this or did you find some other alternative? 

(ENG) I have XPS 15 9570 whit I7-8750H; windows 10 pro (version 21H2) and i have this problem: "DRIVER_POWER_STATE_FAILURE" whit blue screen of death.
Occurs sporadically and without any apparent problem.
i hope that Dell find the solution.

(ITA) ho XPS 15 9570 con I7-8750H; windows 10 pro (versione 21H2) e ho questo problema: "DRIVER_POWER_STATE_FAILURE" con schermo blu della morte. Si verifica sporadicamente e senza alcun problema apparente. Spero che Dell trovi la soluzione

From what I learned, I think it has to do with some incompatibility issues, but I do not have any fix yet. I will try to contact Dell directly, but at least until now the problem is still not solved.

I started to have the blue screen error that reads Driver Power State Failure. It happens randomly. Sometimes as an omen of bad luck, my mouse freezes (both the BT and touchpad) while everything works, and then after a minute, I get a blue screen error. Sometimes everything freezes, and I get the blue screen. I don't know if it's a coincidence or not, but I have updated to windows 11. I had no such problems when I used windows 10.

Exactly this happens to me too after updating to Windows 11.

There is no clear pattern in the occurences, although it seems slightly more prevalent when the system is running more resource-intensive programs such as programs from the Adobe Suite and/or web development software.

I've updated all drivers through Support Assist.

(ENG) Usually my notebook is connected to the power supply, but in the course of the working day I happen to disconnect it, and on those occasions the BSOD screen happened, but I repeat that the occasions are completely random.

(ITA) Di solito il mio notebook è collegato all'alimentazione, ma nel corso della giornata lavorativa mi capita di scollegarlo, e in quelle occasioni è successo la scermata BSOD, ma ripeto che le occasioni sono del tutto casuali.

Hi, I am also seeing this problem with XPS 15 9510 lately.  I have yet to upgrade to Win 11 and the machine was working fine until recently.  In the last week, it kept freezing, usually my mouse is frozen (esp. if I left it inactive for a while) but the keyboard remains operational until the blue screen comes up.  When I restart, the blue screen comes up too.  Can it be a clash with the driver of my Dell wireless rechargeable mouse ?  I have followed Dell's support team's advice to do everything, even resetting my machine using OS recovery tool.   The problem still comes back.  Hope Dell can investigate this as XPS is supposed to be a very stable machine.
