I have since March this machine which is giving me quite a lot of problem.
I had several BSOD (or the nicer version Win 10 provides) since several months. I updated even the BIOS.
Now it seems related to a specific situation: if the notebook is connected to power supply and goes to sleep.
If instead it relies on battery, such issue does not occur.
Looking at the minidumps, I notice the main error is always the same PAGE_FAULT_IN_NONPAGED_AREA caused by ntoskrnl.exe + 1640e0
As I use my machine for computations, it becomes really and issue. If I close it and force it to sleep, everything seems OK (or less reproducible events). I made the Lenovo tests and nothing looks wrong. Missing the CD, I do not know how to make a memtest.
I read elsewhere that it be related to nvidia drivers, which I do not think concern this machine.
I will attach the minidump files.
Thank you for your suggestions and help.
