Missing Drivers

[TLA2]

Hi,

Can anyone help please?

At the school I work at we bought 2 new HP 250 G4 notebooks. They came with Win 10, I had to change that to Win 7 via a full reinstall. However now that I have done that there seems to be 2 drivers missing that I can not find, even on the HP website. I am not sure these are needed but need to check. 

The drivers are PCI simple communication Controller and the other says unknown device but when I click on it is says Microsoft ACPI-compliant system. 

Does anyone know if I need these as have been told it maybe due to going fron Win 10 to Win 7?

Many thanks

Here is the driver page:

We need you to find the hardware ID of the devices. Right click on the device in device manager, select properties, then details and then pull down the menu to hardware IDs and tell us what you see.

Hi:

For the PCI simple communication Controller, you need this driver...

This package provides the Intel Management Engine Interface (MEI) Driver for the supported notebook models and operating systems. The Intel Management Engine Interface enables communication between the host operating system and the Intel Management Engine firmware.

As Huffer stated above, we would need you to post the hardware ID for the unknown device, as there can be one of several devices listed as unknown, and I am not one that recommends the trial and error driver installation method.

Here is how you find the hardware ID...

Go to the device manager and click on the Unknown Device.

Then click on the Details tab at the top of 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 Paul,

Thank you for the reply, the driver for the PCI has work, nice one.

Here is the ID  for the other

ACPI\MSFT0101  *MSFT0101
  That is all the information it has given me, hope that is all that is need.

Thanks Shane

You're very welcome, Shane.

For the unknown device you need to run the Microsoft Hotfix from the link below.

That is the TPM 2.0 device that needs a driver, and none are available for W7.
