I bought a brand-new Lenovo Yoga 9i (model 16IPH11) about three months ago. Aside from the touchscreen pen not working, it has developed a much more serious problem: more than 50 seemingly random blue-screen crashes. Sometimes the laptop runs for weeks without an issue, while other times it crashes five or more times within half an hour.
I have updated Windows, installed every driver offered through Lenovo Vantage, performed a fresh Windows installation, tried rolling back various drivers, and run a roughly six-hour hardware/BIOS diagnostic scan. None of that found a problem or stopped the crashes. The main bug checks I have seen are:
- 0x10E — VIDEO_MEMORY_MANAGEMENT_INTERNAL
- 0xC4 — DRIVER_VERIFIER_DETECTED_VIOLATION
- 0xC9 — DRIVER_VERIFIER_IOMANAGER_VIOLATION
An analysis suggested that a graphics driver or hybrid-GPU power-state transition could be corrupting GPU memory. I am also wondering whether Photoshop is triggering the problem, since two crashes happened close together and the second occurred shortly after opening Photoshop following a reboot. The laptop was running on battery at the time.
Lenovo wants me to send the machine away for 7–12 business days, although they may be able to send a technician to my home. Before I give it up during university study, I would like to know whether anyone has dealt with similar crashes or can identify a likely cause. I can provide the crash dump analysis if that would help.

The most useful next step is to collect several minidump files from C:WindowsMinidump. Copy them somewhere else, compress them, and share the files through a public file host that accepts archives. One dump can be misleading, while several crashes may reveal the same driver or device.
If minidumps are not being created, configure Windows to use Small Memory Dump files and reproduce the problem. The actual dump contents are much more useful than a general description because they can show which driver was active when the crash occurred.
A completely clean Windows installation from USB is worth trying, rather than reinstalling from within the existing system. During setup, delete the old Windows system partitions and let the installer recreate them. Then install the current BIOS and Lenovo drivers from official sources.
If the crashes continue on a clean installation with updated firmware and no extra applications installed, that makes a hardware or firmware fault much more likely. At that point, warranty service is the appropriate route.
The 0x10E error is the most concerning one because it points toward the video-memory manager. On a system with only integrated graphics, that memory may be shared with ordinary system RAM; on a system with a dedicated GPU, the graphics memory or its driver could be failing.
The 0xC4 and 0xC9 errors involve Driver Verifier and usually indicate a bad driver or an illegal device memory access. If you manually enabled Driver Verifier, disable it because it is designed to force problematic drivers to crash and can make the system appear less stable. If it was not enabled manually, the dump files become especially important. The 0xC9 crash may also require more complete debugging data than a small dump provides.
I tried examining one of the 0x10E dumps, but the device-object command returned a null address and could not find anything. I am not sure whether I need to analyze another dump or whether that result is expected from a minidump.
I installed Windows through the online reset process, so I had not deleted the system partitions. I will look into doing a clean USB installation. For the BIOS, can I use the Lenovo Vantage updater, or should I manually flash it?
