unexpected shutdowns

2021-07-23, 18:20 PM

My relatively new (5 months old) P340 workstation has gotten into the habit the past month of powering down on its own.

 

It gets into a weird state where it's not pingable, doesn't respond to keyboard input, plugging/unplugging the HDMI cable makes no difference (screen stays blank).  The only ways I've found out of this state is to press and hold the power button, which turns the machine off, or unplug the power cable and plug it back in.

 

It's happened about 6 times over the last few weeks, after being stable for months.  

 

I can't find anything of interest in any of the system logs around the time of the shutdown (just the error from Windows, when it starts up, saying it was not properly shutdown.

 

Any thoughts or troubleshooting steps would be awesome, thanks!

Do you have any idea of what the system was doing prior to the hang condition?  Is Windows possibly hitting a blue screen and crashing?  Was the system under heavy CPU or GPU load?

 

What is your full system configuration?

 

The first step would likely be to try to figure out if it's a SW issue causing the problem, or possibly something on the HW side.  I'd suggest making sure your system BIOS and all core drivers are up to date if possible, but obviously the system needs to be up and running to be able to accomplish this

The system wasn't doing anything remarkable.  I don't do anything that really pushes the envelope.  A few times I was actively using the machine, but other times it was just sitting idle.  

 

It doesn't hang and doesn't go to a blue screen.  It just goes...I'm not sure what the correct word is...dormant.  The red power light is still on, one the front panel, but it otherwise appears to be powered off and totally unresponsive.  I haven't run into this with any machine before.

 

The BIOS and drivers are up to date and I ran the HW scan that comes with the Lenovo Vantage and that come up green.  I looked at things using CPUID HW Monitor just to see if things were running unusually hot, but they weren't (30 C across the board).  Not sure what else to do.

 

My configuration is below.

The BIOS isn't quite up to date, but it's only one level back (the latest posted version is S08KT3FA from July 22nd).  If the system is typically in the OS when this condition shows up, I'm really tempted to think it's something SW related as opposed to a HW issue.  But that's mostly a hunch based on previous experiences.  

 

Have you seen anything interesting in the Windows Update logs?

 

The system summary doesn't provide complete info on the system config:

  - Is there a discrete GPU installed in the system?  Or is it using onboard graphics?

  - What is your storage configuration?

 

You could start attempting to work through a standard debug process by removing various pieces of hardware one at a time to try to get that to trigger something, but that can be difficult to do with a problem where the system is intermittently crashing from within the OS and honestly might not get you anywhere if it is a SW problem.  So I'd probably recommend focusing on BIOS, drivers, and the OS.  Not ideal, but a clean reinstall of the OS might tell you a lot, especially if you have another spare drive you can use for the clean OS install.

Thanks mate.

 

Since it's still under warranty, I contacted Lenovo and within a day they ordered a new motherboard.  I wonder if it's a known issue with this model?

 

I'll reimage and refresh the BIOS and hopefully be in calmer waters.

 

Thanks again for taking the time.  I'll post back here if the new motherboard does the trick.
