Hi:

You need these drivers for the devices you listed...

 DPTF Framework Device:

This package contains the driver that enables the Intel Dynamic Platform and Thermal Framework firmware. Intel Dynamic Platform and Thermal Framework provide system temperature and power utilization information for the system thermal
protection to function properly. This package is provided for supported notebook models running a supported operating system.

PCI- Ver-/Entschlüsselungscontroler:

This package provides the Intel Trusted Execution Engine Interface (TXE) Driver for the supported notebook models running a supported operating system. The Intel Trusted Execution Engine Interface enables the Secure Boot and provides services required for platform security features such as Intel Platform Trust Technology (Intel PPT).

ftp://ftp.hp.com/pub/softpaq/sp71001-71500/sp71264.exe

If the unknown device has a hardware ID of ACPI/INT3400, then the first driver should also install that device too.

Hi, Thx for coming back quickly.

I downloaded ftp://ftp.hp.com/pub/softpaq/sp71501-72000/sp71638.exe and installed.

At the end of the Installation win 7 mentioned that the program was not install sufficient. 

I tried it again - same message again

Hi,

I was able to install the latest driver what you propose.

With a trick you proposed in another posting - decompress files and update via Device manager

  

Please have a lock on that picture - still 2 unknown devices PIC

Hi, Tom:

Please post the hardware ID's for the other 2 unknown devices.

To find the hardware ID, click on each unknown device.

Then click on the Details tab on the unknown device window.

Now you will see a Property drop down list, and it will be set to Device Description.

Drop down on that list and select the 2nd item (Hardware ID's).

Post the top string of characters that you see in the window.

Hi, Tom:

The left side one (22DC) is also part of that intel thermal dynamic system, so try manually installing the driver like you did for the other ones (using my trick).

The 2nd one needs this hotfix installed...

You're very welcome.

If you can't get the hotfix to work, I have zipped up and attached the driver below.

See if my TPM 2.0 driver works on your model.

You install it by the same manual method you did for the Thermal Dynamic driver.

Download and unzip the file I attached to its folder.  Do not do anything with the files in the folder.

Click on the unknown device needing the driver, click on the driver tab, click on update driver, select the Browse my computer for driver software option, browse to the driver folder you unzipped, make sure the include subfolders box is checked and see if the driver installs.
