TPM Event Error 13 may be logged on Windows Server 2008 and Windows Server 2012

Applies to: Windows Server 2008 Service Pack 2Windows Server 2008 StandardWindows Server 2008 Enterprise


1) TPM Event Error 13 is logged in the Windows System Event Log occurs during boot.
Log Name: System
Source: TPM
Date: 11/9/2011 6:28:45 PM
Event ID: 13
Task Category: None
Level: Error
Keywords: Classic
User: N/A
Computer: 37L4247E20-11
The device driver for the Trusted Platform Module (TPM) encountered a non-recoverable error in the TPM hardware, which prevents TPM services (such as data encryption) from being used. For further help, please contact the computer manufacturer.
2) Device Manager still shows the TPM Security Device as present.

Example Scenarios where this might be reproduced:

NOTE: The TPM event 13 will occur regardless of whether the TPM is Enabled/Disabled or Activated/Deactivated and only at boot.

1) Enable Physical Presence via BIOS or Jumper (TPM Assert) within server chassis. 
2) Perform combination of Enable & Activate or Disabled & Deactivate within the UEFI BIOS Security configuration and install Windows.
3) Boot into Windows.
4) View Device Manager and verify if TPM Security Device instance is present.
5) Go to Windows Event Viewer and note if TPM Event 13 was logged after Disabling & Deactivating or Enabling & Activating the TPM Device from within UEFI setup.

You may also encounter a .NET Framework exception when loading a snap-in or other component from the MMC console.


This is a known issue with Windows Server 2008 SP2 and Windows Server 2012 on some IBM servers that cause a response code from the TPM which triggers the event error during boot. 

NOTE: Certain TPM commands are designed to be un-usable when the TPM is disabled or deactivated.


In this scenario the TPM Event Error 13 can be safely ignored.

More Information

This has been known to occur on the following family of IBM xSeries of Servers: 366, 460, 3850, 3950 and possibly other models.

With Windows Server 2008 R2, when the TPM is Disabled & Deactivated or Enabled & Activated, Windows will not log an TPM Event 13 error.

In both versions of Windows i.e. Windows Server 2008 and Server 2008 R2, TPM presence will be shown in device manager even though it may be Disabled & Deactivated, this is by design.

It is not recommended to disable and prepare the TPM in succession.
