Hp doesn't completly shut down

A client brought an Hp computer (Hp Z240 Small Form Factor Workstation) that will not completly shut down.  the on/off button still stays on and you can't start the computer back up again.  You have to unplug the computer and then it will start up. When it starts up it gives a couple of error messages before going to windows boot-up.  Here are the pictures of the error messags. I did a BIOS Update but that didn't help.

Intel Management Engine is corrupted.
Try unplugging machine, unplug cmos battery and wait 30 minutes, reassemble and try again

Intel Management Engine ver:11.0.4.1186 is a driver found in Downloads:

Thanks David, I will try that first thing in the morning when I get back in the shop.

to bleed the charge  i just hold the power button for 10 sec when everything is disconnected....much faster
i would try if it boots to safe mode  :
From Settings
  1. Press Windows logo key + I on your keyboard to open Settings. ...
  2. Select Update & Security > Recovery . ...
  3. Under Advanced startup, select Restart now.
  4. After your PC restarts to the Choose an option screen, select Troubleshoot > Advanced options > Startup Settings > Restart.

Ok, I unplugged the machine, took out the battery and after 30 minutes I re-installed the battery and and the computer acts the same way.  I attempted to install the Intel Management Engine but it says that it is not supported by this platform. I then went to the hp website, downloaded the Intel Management Engine driver from there but got the same error message. I am now downloading and installing all the optional updates to see if that will help

I will also try your suggestion, Nobus
nobus

check also event viewer for errors   +   the bios battery - it should read 3V min
do you have a PS that you can swap ?  it can be a bad PS

I did  a BIOS update but the issue still persists

answer to Nobus: I do not  have a PS that will fit this particular computer.  I will check the voltage and install a new battery in the morning. David, if the IME section is corrupted is there any way to fix that other then a BIOS Update?

if you don't have a PS - you can still measure the voltages on the ATX connector :

This is not the standard PS Connector.  The picture will show you the connector configuration.  The two connectors circled are coming from the PS
Here are the voltages:
PS connector (2).jpg
Running                  Not Running
Blue       11.39V        .5MV
purple     12.23V      11.57V
Yellow     12.27V       .2MV
Yellow     12.27V       .2MV

Gray          3.29V       13.9MV    
Green      34.9MV       3.63V
White         1.79V        0
Red            2.7V          0
Note that When I use the shut down method and the computer appears to shut down (but doesn't, power button and fans continue to run) the voltages are the same as when the computer is running.
