Precision 7875 turns itself back on from shutdown
I got a new Precision 7875 workstation with a bit of a strange problem.
When I shut down the computer, it turns itself back on after one or two hours.
BIOS versions tested: 01.01.37, 01.02.42
I already have gone to quite some testing and troubleshooting myself.
I checked my BIOS settings and disabled network boot, wake on LAN, USB wake support, set AC recovery to power off and disabled Auto On Time and read this Dell KB article 000126172 "Resolving Computer does not shut down or turns itself back on"
https://www.dell.com/support/kbdoc/en-us/000126172/cannot-shut-down-computer
BIOS settings:
Windows settings:
Fast Startup is off:
Wake timers are disabled
Wake up for automatic maintenance is off:
No devices are allowed to wake up the computer:

Good troubleshooting by the way.
Fast startup only starts after POST if I have that right.
Due to your extensive troubleshooting, I don't have any new ideas, except one. Try the "Get help now" button on the lower-right of the screen.

I did perform a RTC reset a day ago as it was advised in other cases.
https://www.dell.com/support/kbdoc/en-us/000126023/how-to-reset-real-time-clock-rtc-to-recover-your-dell-desktop-system
But unfortunately, the problems remains.
I hope the Dell engineers can make a BIOS update in which this issue is resolved.
I have gotten in contact with Dell support via Get help now, but it took hours to get a reply and when I got in contact with a support agent I only had a short amount of time before I had to go myself. I linked to this forum post.

I have been in contact with Dell support. They instructed me to run ePSA diagnostics which shows an error code 2000-0145 on a Corsair MP600 Pro NH 8TB SSD that I added myself to one of the m.2 2280 slots. Under Windows, with SMART diagnostics and the Corsair SSD toolbox the SSD shows no problems and works fine.
But as this is a part that was not installed by Dell it is not supported so I will need to test if the uncommanded boot problem persists if I remove this SSD.

The uncommanded boot problem ONLY occurs when my user-added 8TB Corsair SSD is present in the system. So I think there is a compatibility problem between the Dell Precision 7875 and this Corsair MP600 PRO NH SSD. When The SSD is removed, my workstation stays off as it should when shut down.

Glad you found the problem. :)
Crucial is a good brand if you want to try it. I've used their SATA SSD's myself.

@bradthetechnut Thanks. Dell also 'helpfully' directed me to their sales agents to suggest me buying a compatible SSD for my system but I thanked them for it. I'm not interested in buying another SSD at this time. Dell charged the same price I paid for my 8TB SSD for a 4TB one and did not offer an 8TB m.2 SSD in their configurator. Crucial does not seem to have a 8TB m.2 2280 model for sale. So I will stick with my 8TB Corsair. It is lightning fast and completes all SMART / surface tests without problems. Perhaps the compatibility issue will be resolved later of more customers ran into similar problems. The entire issue has given me some mixed feelings. I fully understand that Dell support is limited on third-party hardware issues. But at the same time: A PC like this is an open platform. I should be able to add third party SSD's without these issues.

I made a ticket with Corsair support for this issue. Here is their answer:
