Bios Settings Following Harddrive

I have a Dell xps 9510 that has had 4 different motherboards installed. 2 for power rail problems. These seem to be resolved now. However now Bluetooth is disabled within the bios. There is no way to enable it as the option is greyed out. I am aware this is selected when the service tag is programmed by the tech. Did they just screw up programming twice or is it possible that once Bluetooth was disabled once now this setting is following the harddrive? Windows was not reinstalled and everything else seems to work fine.

No, BIOS settings don't leave the BIOS.

 

If you want to check, unplug the harddrive, reset BIOS, and nothing will be any different.

On HP laptops, a backup BIOS image is saved on the boot drive, which is great if the board supports BIOS flashback, but the instance where I needed BIOS flashback, the board did not support it.

That’s entirely possible, but unless you actually go out and try and load that bios save, it won’t arbitrarily decide to load it.

If it detects a corrupted BIOS, during BIOS repair on startup, it will attempt to call upon that save.

Hmm. Well, that is interesting. I am surprised it would have a subroutine to check for corrupted BIOS seeing how rare this is. 
 

But, regardless, for the OP, if they disconnect the harddrive it would make this impossible for the system to do and would prove one way or the other if BIOS is someone being pulled from the harddrive (I really doubt it is).

I mean, seems like a pretty simple if-then.

If          BIOS check = fail

Then   load BIOS recovery image.

Sure, but this is such a niche thing. I have built and maintained well over 50 PC’s, never once have I seen BIOS get corrupted. ¯\_(ツ)_/¯.
 

Again, OP can very easily test for this.
