Does HP Notebook 15-BA009DX have a TPM

Does HP Notebook 15-BA009DX have a TPM chip? 

Latest Windows upgrade took my version to build 18xx and now TPM initialization fails? Does this notebook have a TPM chip or is this just another Windows bug/ 'gem'? 

Next question which is related 100%:  should I suspect a rootkit virus in relation to TPM initialization failure?

Invoke the Device Manager and click on the Security Devices section. Look for a Trusted Platform Module 1.2 or higher.

My current HP product loan Spectre x360 15t-ch000  has Trusted Platform module 2.0 with Windows 10 Pro installer 

If it is present, your notebook has a TPM a module and you can use Windows BitLocker encryption if you have Windows 10 Professional installed.

There is no point to your "100% related"  next question if the module is not present.

It's not TPM 1.2 it’s TPM 2.0 and it's failing to work correctly according to event viewer. (Error below)

This is only seen since yesterday’s Windows 10 update took my build to 1803. Never seen this 'failure to execute' before.

Exact error message in event viewer is: Trusted Platform Module (TPM) hardware failed to execute a TPM command.

I take it that you did not read my previous reply carefully.

The error is likely to be a Windows 10 update issue.

Why not roll it back to the previous build to see if the issue happens again?

Good idea but Rolling back an update means it will just install itself again.  MS forum has nothing to help me understand what and why except to contact HW manufacture. Which is why I am asking here and why I suspected a rootkit virus.  Yesterday lunchtime I was loading software to change from Avast free (very good av) to Norton premium (new to me) when Windows interfered and did it's update (even though update is set to use idle time and idle time is set to 3am) and wondered if something got in during the transition. 

Do you have any knowledge of TPM behavior wrt rootkit viruses (and antivirus workings)? 

With 3 things at play here I'm not sure where to start. I started with MS, they said it's hardware, so I'm here now because google search comes up with nothing useful re my model HP Notebook.

Update if anyone is interested:  I was only going to reinstall the latest (heavy) Windows 10 update as a very last resort so was very reluctant to do this as it will not tell me what 'fixed' the problem should it return again.

I seem to have resolved this issue by creating a workgroup only I reside in.  (While Windows update ran and ran.....and ran the other day, it took so long I gave up supervising/ watching it and went to sleep, my connection to the internet turned off as 'bedtime'  mode is enabled on our router, but the update had not finished doing it's thing when bedtime mode kicked in. Today, when I viewed the events (in event viewer) that unfolded after bedtime mode kicked in, I saw my pc's windows had put itself (!!?) into a workgroup with my son's computer and that my son's PC was advertising itself as the master browser within the workgroup thus forcing an election every so often when my pc contested that status. After I saw this, I made a workgroup for just my pc and my TPM problem stopped. )  

Why this worked is a mystery to me ( my knowledge is outdated as my last MCP certificate was in 2000 and I haven't worked since 2001, but one thing hasn't changed - Windows is still buggy, heavy and now does more for MS themselves at users' expense than it does for the users who pay for it. )
