Unexplained HANG on P50 + any release of VirtualBox + 3-5 virtual machines once every 1-3 months

2017-02-17, 10:58 AM

This occurs on Windows 7 64-bit Pro and only when working with three external monitors.
I emphasize that this is not the BSOD!
At this point all external monitor "freezes" the last frame, and on a laptop screen - black screen appears and the laptop freezes finally .
The Windows event log of any "before" or "after" there is absolutely no suspicious events.
After a forced reboot the laptop is running as if nothing had happened.

Nobody watched like?

I was already beginning to annoy terribly the described situation.
Why I spent so much money on professional laptop the high reliability and performance (P50) if absolutely "out of the blue" this laptop just suddenly comes to a screeching halt showing a black screen and not reacting to anything except the power button?!
And this happens about every 2-3 weeks.

Under heavy synthetic stress tests for many hours the laptop works without problems!

I don't think this is a particular Thinkpad/Lenovo problem. I normally run 3 VM's with Linux as a host and various Windows versions (Win 2000, Win 7 64/32, Win 10) as guest OS. I found that VmWare on a Redhat host runs the most stable. Virtualbox seems a bit buggy sometimes, specially on Windows 7 hosts (haven't tried Windows 10). I wanted to run this scenarion on my P70 (Xeon/32GB/ECC), but unfortunately the P70 BIOS is such a pile of crap that I decided to sell my P70. Again I would advise to use 'Vmware Player' over 'Virtualbox', usually Windows is the weaker point than your P50. You can also install Linux (Fedora 25 or ARCH work fine, with tinkering CentOS/RedHat 7)

PRIME-OS,

Unfortunately, not so simple!
I managed to reproduce everything I wrote above without Virtualbox.
If you give the laptop a synthetic test not 10-15 minutes, and about an hour, that is a very high probability of "catch glitches" described above. That's exactly what happened to me.
I'm afraid that P50 is either not designed for long-term work under stress loads, and even under stresses far from stressful, when the temperature for a long time exceeds 65 degrees Celsius (although it does not even reach 80 degrees Celsius).
Probably throttling processor or video card Nvidia Quadro does not work properly and the laptop simply "catches" thermal shutdown!

It is especially offensive to assume this, knowing that the P50 has such an advanced cooling system consisting of two coolers and a pile of heat pipes.

Perhaps in my version, I'm wrong, and the P50 just does not work correctly switching between video cards when working with external monitors, because of what a potentially critical hardware failure may occur.

And it's completely offensive if such problems are limited solely to my copy of the P50.
