Upgrade Your HP Laptop / PC To TPM 2.0 - Admin-enclave

According to Microsoft the Windows 11 OS required a TPM version 2.0 in order to get in running. The TPM 2.0 is normally installed in many newer devices (not older then 3-4 years). However in some older devices a TPM 1.2 might be installed which can be upgraded to TPM 2.0

However not every TPM Chip can be upgraded from 1.2 to 2.0. There are only a handful TPM Chips on the market which can be updated.

But, if you have a:

Infineon SLB9660 (which one after updated should change the name to SLB9665) [SLB 9660TT1.2, SLB 9660VQ1.2, SLB 9660XQ1.2, SLB 9660XT1.2]

Which is for example inside the following devices (see reference here):

• HP Chromebook 11 G4 EE HP Chromebook 11 G5 HP Chromebook 14 G4 HP Elite x2 1011 G1 Tablet HP EliteBook 1020 G2 HP EliteBook 1040 G2 HP EliteBook 612 G1 HP EliteBook 720 G2 HP EliteBook 725 G2 HP EliteBook 740 G2 HP EliteBook 745 G2 HP EliteBook 750 G2 HP EliteBook 755 G2 HP EliteBook 820 G2 HP EliteBook 840 G2 HP EliteBook 840 G2 HP EliteBook 850 G2 HP EliteBook 850 G2 HP EliteBook Folio 9480m HP EliteBook Revolve 810 G3 HP Pro Tablet 608 G1 HP Pro x2 612 G1 HP ProBook 11 EE G1 HP ProBook 430 G2 HP ProBook 440 G2 HP ProBook 445 G2 HP ProBook 450 G2 HP ProBook 455 G2 HP ProBook 470 G2 HP ProDesk 400 G2.5 HP ZBook 14 G2 HP ZBook 15 G2 HP ZBook 15u G2 HP ZBook 17 G2 HP 260 G1 HP 260 G2 HP 285 Pro G2 HP EliteDesk 705 G1 HP EliteDesk 705 G1 HP EliteDesk 705 G1 HP EliteDesk 705 G2 HP EliteDesk 705 G2 HP EliteOne 705 G1 HP EliteOne 705 G2 HP ProDesk 400/480 G1 HP ProDesk 400/480 G2 HP ProDesk 400/490/498 G1 HP ProDesk 405 G2 HP ProDesk 485 G2 HP ProDesk 490/498 G2 HP t530 Thin Client HP t620 Thin Client HP t630 Thin Client HP t730 Thin Client HP Z440 Workstation HP Z640 Workstation HP Z840 Workstation HP Spectre x360

You can download an update from the HP Website here and update the TPM 1.2 to 2.0.

The following TPM Chips couldn´t be updated from TPM 1.2 to 2.0:

• Infineon SLB9635
• Infineon SLB9645 (SLB 9645XQ1.2, SLB 9645XT1.2)
• Infineon SLB9656

Troubleshooting steps If the update isn´t working:

1.) Make sure that TPM is enabled in the BIOS

2.) Try to perform a BIOS reset (reset to factory defaults)

3.) Try to disable the TPM auto-provisioning temporarly (we´ll turn it back on later):

3a.) Open Powershell as Admin and run:

Disable-TpmAutoProvisioning

3b.) Reboot the PC and go into the BIOS. Navigate to “Security -> TPM 1.2/2.0 Security”. If TPM is disabled there, enable it. If not click on the clear checkbox and select yes to clear the TPM settings. Then boot into windows.

3c.) Re-Run the TPM 2.0 Firmware Update Utility and let your PC reboot

3d.) Once your PC is back re-enable the TPM Auto Privisioning. Open a Powershell as Admin and run:

Enable-TpmAutoProvisioning

3e.) After that reboot your PC again

3f.) Open tpm.msc and make sure that TPM is active an provisioned
