Windows 10: BSOD Across a Number of Lenovo Laptops Win10

HI,
I have been getting BSODs on a number of Lenovo PCs (T540-T570 and X260-X270) all of them run Windows 10 1803 build. I run windbg on the minidump and it almost 90% returns ntkrnlmp.exe I have attached the minidump from the most recent one. I can't pinpoint the problem. I know something triggers the ntkernl and causes the BSOD. Any help would be highly appreciated. Attached is the most recent BSOD minidump as zip.

 

Multiple 0x0000009c BSODs on Windows 10 Lenovo Laptop


Symptoms:

• Windows 10 Pro BSODs randomly (after freezing). I have almost 12 identical dumps (attached).
• There seems to be no pattern to it but sometimes it happens when the machine is idle.
• The machine just hangs and then eventually reboots -- most of the time I don't even see a BSOD screen, it just goes from a frozen screen to reboot and the dump is generated.

Steps Taken With No Success:

• Ran full memtest with no issues.
• Clean Windows reinstall.
• Changed from HDD to Crucial SSD.
• Updated BIOS and drivers to what I think are the latest (manufacturer website).

Important System Characteristics:

• Lenovo Z70 laptop with dual Intel 5500 and nVidia GeForce 840M graphics cards
• Virtualization technology is turned on in BIOS in order to run virtual machines
• The BSODs stopped for a good while and then started up again quite frequently lately. I haven't been able to pinpoint any changes in how I use the machine.

Most of the dumps seem to point to intelppm.sys --I'm not sure where to go from here.I have attached the output of the information DM log collector. I have gone through all the files and sanitized them to remove any sensitive personal information (according to me) but that shouldn't affect the integrity of the information.

 

Win10 laptop w/laptop display (no others) labeled 2, can't change to 1


alphanumeric and Helmut, Thank you for your replies.

1. The drivers were installed when Windows 10 was installed. There was nothing on the laptop prior to installing Windows 10.
2. I don't have another display to try attaching as suggested.
3. Not sure if it's always been like this or not. I just started looking at the configuration settings a week or so ago.
4. To check hardware status, I've run a bunch of Lenovo tests and update checks. Nothing found.
5. I did the Device Manager suggestion. 2 PnP monitors listed ... clicked "Show Hidden devices" ... found 2 more PnP monitors for a total of 4 ... uninstalled all 4 ... restarted ... same situation. Results: Device Manager now only lists 2 PnP monitors total (no hidden monitors) even though the only monitor is the laptop built-in monitor, but no change on the designation of laptop monitor being number "2" monitor.

Thanks for your help and suggestions. Not sure why it is like this. Might be something like Win10 compatibility, old hardware, or similar.

I've taken enough of your time on this. I can live with it as it is. Might decide to upgrade to a new and current laptop, or just proceed as is. Anyway, your responses are greatly appreciated!
