Optane reporting SMART errors - CrystalDiskInfo shows no SMART errors

A few days ago my wife's laptop started displaying Optane popups reporting SMART errors. I quickly downloaded CrystalDiskInfo, ran it, and it showed no errors. I read somewhere on the web that this could be errors in the Optane cache rather than in the drive itself. Unfortunately, I know nothing about Optane so don't know how serious this is, but it sounds bad. I looked at the ElevenForum thread here but understood next to nothing.

This is a Dell Inspiron 17 - 3793. It has a Sumsung SSD so I don't think it really needs Optane. From the doc I see that the Intel SATA/PCIe RST Controller supports Optane but as far as I can tell there is no Optane storage installed. (I don't have access to the laptop right now. I'm looking at data collected by Speccy and Belarc Advisor. I very well could be misinterpreting the data.)

Whether or not there is any Optane memory, Optane code must be running since it's reporting an error. Should I just disable it and see what happens?

BTW, the laptop is running with very old BIOS. I would update it, but the last 10 BIOS upgrades have caused failures in the wireless adapter. I reported this to Dell last January and they said it would be fixed in a future BIOS upgrade, but there have been 5 upgrades since then but no fix. Hence, the laptop is back on a very old version of BIOS. The old BIOS could be involved in the Optane/SMART error but that wouldn't explain when the Optane/SMART error just started last week.

Hmm. I can't edit my post. Maybe because it was moved.
Anyway, here's some more information. I got on the laptop, got into Intel Optane Memory and Storage Management function, and selected "Intel Optane Memory". It tells me "Your sysetem is not Optane Memory ready" and "There are no valid disk pairs in your system". So does that mean I can uninstall Optane Management? There is no (obvious) entry in Programs and Features but there's an uninstall option for it in Start?

If your device is reporting optane errors, it would indicate to me that you do have an optane module installed, so be sure to examine your configuration closely.
The app itself would not be the cause of your errors as it is only a means of managing optane. Go to this Intel page and select which ever error optane is reporting. It should tell you how to resolve it.

Unfortunately, the error message falls into the No Error Code Listed, only an Error Message or Miscellaneous Codes category listed on that Intel page you reference:
Very uninformative and not particularly helpful.

The page they point to says:
Disable acceleration through the Intel® Optane™ Memory management capable application or the BIOS (under the Rapid Storage Technology menu).
Since the "Intel® Optane™ Memory management capable application" claims that no acceleration is enabled (or even applicable) I guess I'll try through BIOS.
