| Description | The TPM's Access register's locality bit could not be set. |
| Event Information | According to Microsoft : Cause : This event is logged when the TPM's Access register's locality bit could not be set. Resolution : Repair or replace hardware components By default, BitLocker is configured to use the Trusted Platform Module (TPM), a hardware component in your computer. The TPM version must be version 1.2, as defined in specifications created by the Trusted Computing Group. For BitLocker to operate correctly, the TPM must respond as expected. Because the TPM is a hardware device, contact your hardware supplier or hardware support team to resolve this issue. Verify : In order for the TPM driver to function correctly, the TPM must be correctly recognized by Windows. To perform these procedures, you must have membership in Administrators, or you must have been delegated the appropriate authority. To verify that the TPM is correctly recognized by Windows: 1.Open Device Manager. 2.Expand Security Devices. 3.If the Trusted Platform Module version 1.2 is not present under Security Devices, or if Security Devices is not shown as a category, your computer might not have a TPM version 1.2, or the computer is unable to recognize the TPM. 4.Right-click on the Trusted Platform Module 1.2, and then click Properties. 5.In the Trusted Platform Module 1.2 Properties window, look at the device status on the General tab. The status should indicate "This device is working properly." If the TPM is correctly recognized by Windows, then you can also verify that the TPM driver is operating correctly. To verify that the TPM driver is operating correctly: 1.Click Start, type tpm.msc in the Start Search box, and then press ENTER. 2.If the User Account Control window appears, click Continue. 3.In the TPM Management on Local Computer window, examine the Status section. The status should indicate "The TPM is on and ownership has been taken." Note: Other application software may also make use of the TPM driver. Consult the documentation supplied with each application for steps to verify the correct operation. |
