Bitlocker question
I have a 3yr old high end Dell laptop. It has Microsoft 10 Windows home edition. This year I had trouble charging it. I replaced the charger, didn't help. I replaced the battery, didn't help. Discussed with a friend who said, you're going to have to get the motherboard replaced.
My warranty was only for two years, so first thing I did was extend the warranty. I opened a case and shipped the laptop to Dell Service over a month ago.
So far I have talked with 5 service technicians, all of whom are asking for the BitLocker key. Windows 10 home does not have Bitlocker on it. I tried explaining this, but I get nowhere. Its like they think I've lost the key. So they ask me if they can wipe the system, and I say no, you shouldn't need to do that.
Edit: The laptop is not encrypted and I was never prompted to set up encryption. I am 99% sure that is not on this computer.
This morning I talked to a supervisor. I think he understood me, but all he said was ok, we'll skip that step.
I thought you could disable TPM in the BIOS and I told him that.
But now I am confused.
Can anyone help me on this?

either a password or a key on a separate drive like a USB drive, they won't be able to replace the mobo and make the computer work again (without a fresh install of Windows), because the main point of this kind of encryption is to tie the drive to the particular motherboard in use, in essence. Can't take the drive out and put it into another computer and read it.
'The computer' ... is essentially identified by its motherboard. So for all intents and purposes when you put in a new mobo, you have a different computer.
You can't defeat this simply by toggling off TPM on the new board, that would defeat the whole scheme in a very simple and obvious way.
So hopefully they're wrong and/or you have good backups 
Only discussing the problem you'd face if it WAS, and you didn't have a key to give them.
If you're sure you didn't enable, I'm guessing you're right
