Hello Anthony Damianos,
Thank you for posting in Microsoft Community forum.
It sounds like your device's BitLocker recovery key was triggered due to the hardware repair. In order to access your device, you will need to enter the recovery key. If you don't have the key, you can try to retrieve it from your Microsoft account if you have one associated with your device.
To retrieve your BitLocker recovery key from your Microsoft account, follow these steps:
- Go to account.microsoft.com/devices/recoverykey.
- Sign in with your Microsoft account email and password.
- Select the device for which you need the recovery key.
- The recovery key will be displayed on the screen.
If you don't have a Microsoft account associated with your device, you will need to contact Lenovo support for assistance in retrieving the recovery key.
I hope the information above is helpful.
If you have any question or concern, please feel free to let us know.
Best Regards,
Haijian Shan
