Welcome to the Dell Community  @girard_m_j 

What SSD/HDD do you have installed in these units???

This would not be the first time that a Dell IRST update has caused problems???

Best regards,

U2

UPDATE: just got in an order of Latitude 5400s...right out of the box, I installed Windows 10 using the latest Windows Media Creation Toolkit, updated Windows, updated BIOS, updated all other drivers and then installed the Inten RST drivers and got a bluescreen on startup.

Laptop was purchased direct from Dell and I did not change anything in the default BIOS settings.

Hi U2,

Thanks for the reply.

I have two laptops that I am currently testing with and reliably getting the BSOD:

The SSD in the 5400 is an SK Hynix BC501 NVMe M.2.

The SSD in the 5480 is a Toshiba THNSNK256GVN8 M.2.

I was just checking to see if there was a connection with another problem resulting from a Dell/Intel IRST update.

But it was tied to the SK Hynix PC300 and the Dell/Intel IRST update.

For your scenario there could still be a connection???

Dell is aware of the 9560 conflict but the work around is to rollback the IRST update.

In fact Dell removed the updated IRST driver that caused the conflict.

They are hoping that the next W10 update will solve the problem.

Good luck and keep us posted if you find a connection or resolution.

I have this same problem.

On latitude 5491 i test Windows 10 1903 and 1909. Install all updates and next RST.

After install RST reboot and Blue screen...

Any idea's?

Hi,

I'm having the exact same issue with a Latitude 5500, I would really appreciate any help.

Thanks

Hi @Rafa_Rdrgz,

After some extensive research and testing, I found that our Latitudes arrived out of the box in RAID mode.  When I switched this to AHCI and reinstalled Windows, the latest Intel RST drivers stopped causing blue screens.

Unfortunately, after you make this change in the BIOS, you will need to install a fresh copy of Windows.  Laptop will not boot if you change it and try to boot to a pre-existing install.

Thank you so much for your answer, I'll do that this weekend. I appreciate the help!

That was an outstanding find!  I never would have thought to check for that on a laptop, but it works!  I can update windows completely now, and, also, update all Dell drivers.

You actually do not need to do a clean install after switching to AHCI when running Windows 10. Just shift+f8 during POST and when you get to the Diagnose/Repair screen, choose Cancel, then Advanced Options--> Troubleshoot --> Advanced Options --> Startup Settings --> Restart --> option 4 (Safe Mode). Once logged in to Safe Mode, reboot and boot into Windows normally.

What this does is disables certain drivers in safe mode, and then re-enables them in normal. Since RAID isn't being used anymore, it shouldn't load those drivers anymore and instead install the AHCI SATA drivers.
