L420 Reporting Result Code WMB01Q002-QN7BKL

After running hardware scan I have a Thinkpad L420 reporting an error WMB01Q002-QN7BKL which is a motherboard issue.

 

What is the exact problem please?

Re: L420 Reporting Result Code WMB01Q002-QN7BKL

WMB01Q002-QN7BKL

w=windows

mb=motherboard

test is 01Q, result code is 002

QN7BKL is a encrypted hash code of your serial number used in feedback and can be ignored. 

 

My MB test checks PCI/e and USB ports.

 

Locate C:\programdata\Lenovo\ldiag folder containing:

ldiag.log    <this log is added to every run of LSC 

ldiag_errors.log

 

For best results, run the MB test only.  Go the ldiag.log, go to the bottom of the log and work your way back to current run.  You may see useful information as to which MB test failed.  

 

Example of my MB log(partial log):

You may or may not see additional information in the log on a failed test.

Otherwise you will have to call the support center.

 

You could also find other hardware diagnostic software on the internet to test PCI/e and USB ports.

Looks like a PCI-E problem
