Event ID 16386 — TBS Operation
Updated: December 16, 2008
Applies To: Windows Server 2008 R2
This version of Windows includes TPM Base Services (TBS), a component similar to an Application Programming Interface (API) , that allows the operating system and application programs to communicate with and share the use of a Trusted Platform Module chip in the computer. The BitLocker Drive Encryption feature uses the TPM by default. Failures or unexpected results encountered by the TBS can result in the TBS or the TPM driver logging event messages.
|Product:||Windows Operating System|
|Message:||An error occurred while TBS was processing power management event. The power management event was %1, and the error code was %2.|
Retry the operation without power interruption
To enable the computer to complete the operation:
- Ensure that you have a consistent source of power (such as AC power or a fully-charged battery), restart the computer, and then retry the operation.
- For lengthy operations, such as enabling BitLocker on a large drive, configure the computer to not enter a sleep or hibernation state during the operation.
If the computer still fails to complete the operation and these steps do not resolve the issue, you might have faulty TPM hardware. In that case, contact your hardware manufacturer or hardware support team.
To perform this procedure, you must have membership in Users, or you must have been delegated the appropriate authority.
To verify the correct operation of TBS:
- Restart the computer.
- Verify that all applications and components that use the TPM, such as BitLocker Drive Encryption, work correctly without errors appearing on screen or in the Event log. Specifically, the following steps can verify the correct operation of BitLocker:
- Verify that Windows Welcome Screen, Logon Screen or Desktop appears. This indicates that BitLocker has correctly unlocked the Windows operating system volume.
- Log on to Windows and access any data volumes that are encrypted with BitLocker.
Note: Data volumes can be configured to be automatically unlocked or to require manual unlocking.
