So I'm thinking that Dell has simply not provided a driver for this device AND the one that Microsoft picks up DOES NOT WORK. The installed driver shows "Microsoft,, 1.488". As expected, Standard SATA AHCI Controller was still in an error state. I manually loaded all drivers from the 5420 driver pack, then connected to the Internet and used Dell Command Update to ensure all drivers were loaded. On initial bootup, the Standard SATA AHCI Controller was present and already in the noted error state. The SATA controller was still set to AHCI.

The ISO downloaded from our MS licensing site. I'm seeing where this is an issue only if the SATA controller is switched to AHCI from RAID.Īs a test, I wiped and reloaded my 5420 with Windows 10 20H2 Enterprise, from a USB drive. The "new generation" notebooks are not ready! I told management to order as many of the prior generation notebooks as we can get. I'm also evaluating a Latitude 5520 and it's broke and went back to Dell for repair.

And if I may rant for a second, this is the second failure of the newest generation notebooks from Dell. Management is eager to order a bunch of notebooks ASAP and this is a problem. I'm going to open a support request tomorrow. Letting device manager attempt to update "automatically" says the same. Both Dell Command Update and Support Assist say that all drivers are up-to-date.

Switch SATA controller to AHCI, as is also our standard. I've installed a fresh/clean copy of Win, our current standard. It is NOT missing! The device is generating an error:Īn I/O adapter hardware error has occurred. I think it's important to note that the driver is indeed loaded. I've been asked to evaluate and approve a Latitude 5420 also and am seeing the same error message in device manager.
