Windows 10: Device listed in MS account but bitlocker key not showing up

Hello,I've had to replace the motherboard of my laptop an ASUS B9. Now the computer is asking me to prompt the bitlocker 48 digits. The bitlocker i assume it was enabled at factory by the manifacturer. The device was correctly registered with my Microsfot account but it does not show the bitlocker ID and Key corresponding to the machine.I've been crawling around and consulted all the sites, including this thread where an user has my same issue: https://answers.microsoft.com/en-us/windows/forum/all/device-is-listed-in-ms-account-but-not-showing/e6b6855a-b615-4d0a-aee3-de05d17ce7cfAny suggestio

:)

 

Old Laptop shows up on devices list but has no BitLock key

My old laptop got fried in an electrical surge and died, it can't be turned on. The BitLock key is required to recover what was on it, which wasn't backed up anywhere, but it doesn't exist. The laptop's decription appears on the devices list in my microsoft account, but not on the BitLock list. The old laptop was a Windows 10. What can I do?

 

Bitlocker key can not be found in the microsoft account

After a regular update of Windows my Notebook asked me for the Bitlocker Key although I never activated this. The device is listed in my account but in the list of keys it's not.

Simply doing a reset is definitely not an option, the data is needed.

Every single suggestion for how to find the key is absolutely useless so far.
