Re: PCI Express hardware test fails - Lenovo X1 Carbon

I think you are experiencing a known problem where the diags will never fail shortly after rebooting, but might fail sometime later.  This is just a diags bug, not a real hardware problem.

 

Lenovo Solution Center 3.2.004 should have the fix for this problem, so can you confirm whether you are still seeing the failure on this version, and provide a screenshot of it?

 

The Lenovo Diagnostics that you are using definitely has this bug, so can you please get the latest version here?

Hi,

 

Thanks for your reply. I couldn't reproduce the problem yesterday, today it is back though.

Even with the newer version of the diagnostics tool you pointed me to.

 

There does not appear to be any functional problem at all so far.

 

Screenshots here

 

 

The problem has never reproduced using the Diagnostics utility in the BIOS (pressing F10 at boot time)

Minutes later, it passes... without reboot or anything.

Sorry for my mix-up, it turns out the fix for this issue is NOT in the versions I told you to try.

The fix is in the next version which is not released yet.

If you want to try the new version before it is released, I'm happy to provide it to you.  Just let me know.

Again, sorry for this trouble.

No problem, your answer is hopeful.

I would like to try the version Next, yes.
I have a problem ticket open with official Lenovo support in parallel with this thread. Their recommendation is a motherboard replacement, so I like your proposal better.

Diags 4.10.0  (not released yet, not signed by Lenovo yet):

The failure as seen on current diags version 4.7.0:

The passing result as seen on 4.10.0 (run immediately after observing the failure above):
