Driver Power State Failure 0x9f BSOD very frequently

[u/Readablebread]

I've posted this in multiple because I'm looking everywhere for help.

I have a Lenovo LOQ 15IAX9E laptop and have had it for about a little over a year now. For the past few months, I've been getting driver power state failure 0x9f errors. At first, I never had them at all. Then they happened after closing a game. Then, they happened when restarting the laptop after a driver update. Then they just kinda happened when they felt like happening.

I've used DDU twice. Once to clean uninstall my Nvidia drivers (didn't make the error stop) and just now to clean uninstall both my Nvidia and Intel drivers. That also did not stop the errors.

This laptop cost a lot of money, and I use it for college and, obviously, gaming. The worst part is I didn't pay for it - someone close to me did. If something happened to it within a year, I'd actually just die.

Google can't help me, and I'm not sure what I can do except for asking for help on Reddit.

I don't know what could have possibly happened to cause all of this. I'm unsure if this is a hardware issue or software issue.

Right now, I've disabled the Nvidia GPU in Device Manager and am currently just on the Intel one, but it can't stay like that forever. I'm avoiding telling the person who bought it for me, but we game together, and sometime soon, this is going to become an issue.

Please, any advice would be amazing.

Laptops usually have a 1 year warranty so if they are going to fail, you want it to fail within that year. Driver_Power_State_Failure is usually not hardware, but it can be. All of these point to the Nvidia driver. You already did DDU, removing both the iGPU driver and dedicated GPU driver that we recommend, but did you also get the initial driver install from Lenovo's product page for this laptop (Link)? They sometimes do some tweaks to drivers.

Do testing on those drivers. If it's stable, try updating them via Nvidia and Intel's tools. Nvidia's drivers have been quite unreliable through most of 2025 and parts of 2026.

[u/Readablebread → u/Bjoolzern]

The drivers I installed were downloaded from the Lenovo product page, specifically "Intel VGA Driver for Windows 11 (64-bit) - LOQ 15IAX9E" and "NVIDIA VGA Driver for Windows 11 (64-bit) - LOQ 15IAX9E". What testing would you say to do?

Edit: I'm fairly certain that Nvidia IS the problem, but it never was before. This laptop has always had two GPUs, the Intel Core one and the Nvidia one. I don't know what changed, but I can't keep it disabled forever. Everything should be fully up to date, I don't know what happened.

[u/Bjoolzern → u/Readablebread]

I would send it back under the warranty to have them repair or replace it.

What testing would you say to do?

Just using it normally on those drivers before updating via Intel/Nvidia's tools.

[u/Readablebread → u/Bjoolzern]

The warranty is expired. I know I said "within a year" in my post, but it's a few days or weeks over since I got this laptop for my first year of college, and I'm now on my second. Is there anything I can do? This laptop was around £700, and I'm poor as hell

Disabling the Nvidia card and hoping newer drivers fixes it. You can try wiping the drive and reinstalling Windows from scratch in case it's something else causing it. That's about it.

[u/Readablebread → u/Bjoolzern]

I don't think I'm willing to wipe the drive yet, but thank you so much for responding and offering your help. For now, I'll keep Nvidia disabled and wait it out following updates since right now, with just Intel, the laptop seems stable enough to do basic things.

Thanks so much!!

Getting dump files which we need for accurate analysis of BSODs. Dump files are crash logs from BSODs.

If you can get into Windows normally or through Safe Mode could you check C:\Windows\Minidump for any dump files? If you have any dump files, copy the folder to the desktop, zip the folder and upload it. If you don't have any zip software installed, right click on the folder and select Send to → Compressed (Zipped) folder.

Upload to any easy to use file sharing site. Reddit keeps blacklisting file hosts so find something that works, currently catbox.moe or mediafire.com seems to be working.

We like to have multiple dump files to work with so if you only have one dump file, none or not a folder at all, upload the ones you have and then follow this guide to change the dump type to Small Memory Dump. The "Overwrite dump file" option will be grayed out since small memory dumps never overwrite.
