Re: Hardware scan failed error WVC007002-UL7WAD

Hi the_old_me , 

 

 

 

Welcome to the Community Forums. 

 

What Machine Number do you have based on the sticker or checking on the support site  ( just the machine number and keep the serial number confidential ) ?

 

Error code WVC007002-UL7WAD show failure on the Video card as per code : 

Usually best to update the Video driver either on the drivers support or directly from the manufacturer 

See if the BIOS version on msinfo32 is as the same version offered on the driver page 

  

Update us how it goes.

 

 

Regards

Re: Hardware scan failed error WVC007002-UL7WAD

A service tip has been released concerning the WVC007002 Mathematical Operations Test error message.  This is a false negative and can be ignored; it does not affect the system's functionality or performance.

I don't think this is a false alarm. My display crashes and recovers all the time while I am using my computer. I already updated all my drivers and the issue still exists.

The model no is 80QD.

I installed the driver from the support website but it did not work saying that its not validated for the machine and I need to download it from manufacturer's website. Its not really clear to me.

 

The display just freezes now and then and I need to restart the laptop quite often.Now a days it does terrible sound.

 

What should I do?

That sounds as though you have a Yoga 700 - but which model; the 700-11ISK or the 700-14ISK?

And which driver did you download from the support site?  Note that these two Yoga models have their own support pages, because not all drivers are the same for these two Yoga 700 models.

 

If you could give us a little more information to work with, we may be able to help you further. Thanks.

I think that there are two issues here:

1) As Andy has posted, there was an issue with the tests that Lenovo Solution Center runs. The WVC007002 Mathematical Operations Test error message gave a false negative and can be ignored; it does not affect the system's functionality or performance.

2) Many people are seeing Windows 10 reporting an error message: "The display driver has crashed and has recovered". This is happening with different makes of graphics hardware (Intel, NVIDIA and AMD), and not just on Lenovo machines.

 

This second error is definitely an annoyance, but it is not fatal. It's a problem with the driver. New drivers seem to have fixed it in some cases (e.g. on my desktop PC, which has an AMD graphics card, the error has gone following installation of new drivers).

 

I see that the latest Intel driver for the Yoga 700 - 14ISK is from 20 January 2016:

 

http://support.lenovo.com/gb/en/products/Laptops-and-netbooks/Yoga-Series/yoga-700-14isk/downloads/D...

 

Is that the one that you have installed? If so, and you're still seeing the issue, then I'm afraid we're going to have to wait until Intel sorts it out with a newer driver. It is indeed annoying, but as I say, it is not fatal.
