I'm having the same problem with some of my 7480s. Not sure how many exactly as some stay on their docks, and it doesn't happen when docked. 

Here is how to duplicate: Re-image with clean ISO of Windows 1803, Go through setup, run windows update, and BAM! Freeze or Whea_uncorrectable_error. 

I did today's bios update and updated/downgraded drivers and it still happens.

Not sure how this can be happening to so many 7480s and we still don't have a resolution. Right now, I have 4 7480s that are sitting unused because of this.

 

 


Hi @gshep86, as I mentioned a few posts above the WHEA bluescreen is related to the video driver and we are waiting on an updated revision from Intel being released. Once it's validated it will be released for download. The BIOS update that you installed was to address the issues that were noted in the release notes. As I understand it their will be a further BIOS update released soon with additional fixes.

Re: Dell Latitude 7480 Laptop that freezes up

  I am having a similar issue with a couple of users with the 7480 latitude's.  It seems they work fine when connected to a docking station (Dell TB16) but once they are disconnected from the docs they get the WHEA_UNRECOVERABLE_ERROR or it just freezes or hangs first.  I am playing with one as I type this and half the time I can't get pass the logon screen before it freezes.  I saw there is a bios update 1.11.1.  I am going to try and install this bios update and see if it resolves it.  Does anyone have any other suggestions to try?

Re: Dell Latitude 7480 Laptop that freezes up

Hi all, 

The video driver update has been released to address the freezing and WHEA bluescreen errors. Can you install the driver and the latest BIOS and let me know if it resolves the issues or if you are still having problems.

Graphics driver A06 - https://www.dell.com/support/home/us/en/04/drivers/driversdetails?driverId=GG5FR
BIOS update 1.11.1- https://www.dell.com/support/home/us/en/04/drivers/driversdetails?driverId=YG7TW

Thanks for you patience and assistance.

Re: Dell Latitude 7480 Laptop that freezes up

Hi,

I have a 7490 running on a TB16 dock and get the same thing.  When running on the dock, it it stable.  As soon as I power it from battery or the original supply, it BSOD after a few minutes.

I have had the dock for a few months now and was able to run it on battery or the original supply OK until a few weeks ago, so I am suspecting something to do with a Thunderbolt Software update. 

I am going to uninstall all of the Thunderbolt stuff when I get time to see if this helps.

regards

Justin

Re: Dell Latitude 7480 Laptop that freezes up

Hi all,

I can confirm I've been running the latest BIOS and video driver updates the whole day without any issues. No freezing or blue screens at all. I'll continue testing with and without dock and update my progress here. So far it looks promising. Tny Alan for your support. Regards, Hrvoje

Fantastic!

I will get these updated drivers to the machines I have and update when we've had a chance to test.

@TracesOfNut

Te 7490 uses the same driver as the 7480 system. Updating the graphics driver and the BIOS should resolve the freezing and bluescreen issues the systems are encountering. Can you try that and let me know if it resolves the issues.

Thanks, 
Alan
