@DELL-Jesse L​ i already update the bios and firmeware to latest version and still the problem , I want to load bios to it's default but there are many options the old owner told me not to change it

I had the same problem on my ~7-8y old Lenovo T480s, but after some research I'd noticed that this is not a vendor but Intel issue. I'd tried to update and downgrade BIOS, restore it to the factory settings - nothing helps.

But I solve it after manual instalation of "Intel Management Engine 11.8 Firmware". I'd pick one from Lenovo webside, but I think that generic one from Intel webside will work too. I don't know if the package from Dell webside has the firmware inside. My BIOS has a place where it reads version of Intel ME software and it was empty, and after I installed package above, BIOS start to read the number, and a error was gone.

One thing to rememeber - I don't know how is on Precision 7530, but I needed to prepare BIOS, for this operation. There is an security option that's prevents installing firmware to the BIOS (and it's different from the one that prevents to upgrade whole BIOS) and it was enebled by default.

Hope it helps.
