260 G3 DM (4YV64EA) - different CPU and no TPM

[HerorBrutor]

Hi all,

recently I bought mini desktop HP 260 G3 DM (PN: 4YV64EA) and after unboxing I found out, that it has different CPU than advertised by the seller and also official HP market site for this PN (Pentium 4415U-advertised vs. Core i3-7130U-real). Nevertheless, better CPU is pleasurable surprise 😉 The worse thing is that the board lacks TPM - it is detected neither in Win10 nor in Linux and also BIOS setup menus don't contain anything TPM-related, although the specs say that TPM 2.0 is included. In addition, the board layout is slightly different than pictured in maintenanceand service guide (the board has more jumpers) and BIOS setup menu structure is completely different compared to description in the guide.

Is it possible that HP changed hardware specs for given PN? Has anybody such experience?

Without TPM, the box is nearly useless for me as I intend to turn Bitlocker on.

HP 260 G3 DM is a series of many different models/products with many different configurations/combinations using the following list

           https://support.hp.com/au-en/document/c06098154#AbT2

But ALL machines have

• Cable lock slot
• Padlock loop
• Trusted Platform Module (TPM) 2.0

Device Manager should show TPM under Security devices

@Banhien thank you for confirmation that TPM 2.0 should be present in HP 260 G3 DM. But in the piece on my table it isn't. Situation in Win10/2004:

- in device manager (hidden devices shown) there is no Security devices category at all

- in Windows Security - Device Security the security processor is not mentioned

- in elevated PowerShell, the cmdlet Get-Tpm says TPM is not present

Situation in Debian 10 and 11:

- no /dev/tpm* device is present

- no tpm* module is loaded

- explicit modprobe tpm* does not discover TPM

I know that missing TPM in OS can be observed when TPM is disabled, but in the BIOS setup there's no setting related to TPM (BIOS is the latest version 02.14.00).

Brgds,
