Laptop starts ok but - An unexpected error was encountered attempting to retrieve the BitLocker volume master key during restart. RRS feed

  • Question

  • My Windows 10 Pro install and all BIOS, firmware, drivers are up to date using  Windows Update and Lenovo Vantage.  I have bitlocker enabled requiring TPM a USB Key and a PIN.  The machine boots fine and I can get to windows but there is a concerning error message that shows up for each reboot.  I can also boot using the recovery key i have on USB by itself just fine.

    Bitlocker-Driver Event 24641

    An unexpected error was encountered attempting to retrieve the BitLocker volume master key during restart.

    Things I've tried.

    I have tried suspending bitlocker and rebooting then re-enabling and I have tried disabling hibernate.   Not much online for this issue.  The laptop is a Lenovo ThinkPad P1 Gen 2.
