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

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

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. &nbsp;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<br><br>

<div>
I will also try your suggestion, Nobus
</div>


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

Its a corrupted IME section in the bios.. try a bios update
</div>


<div>
I did &nbsp;a BIOS update but the issue still persists<br><br>
</div>


<div>
answer to Nobus: I do not &nbsp;have a PS that will fit this particular computer. &nbsp;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?

<div>
if you don't have a PS - you can still measure the voltages on the ATX connector : &nbsp;<a href="https://filedb.experts-exchange.com/incoming/2021/07_w31/1567918/atx-voltage.PNG" rel="ugc"><img src="https://filedb.experts-exchange.com/incoming/2021/07_w31/1567918/atx-voltage.PNG" class="fr-fic fr-dib"></a><br>

This is not the standard PS Connector. &nbsp;The picture will show you the connector configuration. &nbsp;The two connectors circled are coming from the PS<br>Here are the voltages:<br><a href="https://filedb.experts-exchange.com/incoming/2021/07_w31/1567948/PS-connector--2-.jpg" rel="ugc nofollow">PS connector (2).jpg</a><br>Running &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;Not Running<br>Blue &nbsp; &nbsp; &nbsp; 11.39V &nbsp; &nbsp; &nbsp; &nbsp;.5MV<br>purple &nbsp; &nbsp; 12.23V &nbsp; &nbsp; &nbsp;11.57V<br>Yellow &nbsp; &nbsp; 12.27V &nbsp; &nbsp; &nbsp; .2MV<br>Yellow &nbsp; &nbsp; 12.27V &nbsp; &nbsp; &nbsp; .2MV<br><br>Gray &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;3.29V &nbsp; &nbsp; &nbsp; 13.9MV &nbsp; &nbsp; <br>Green &nbsp; &nbsp; &nbsp;34.9MV &nbsp; &nbsp; &nbsp; 3.63V <br>White &nbsp; &nbsp; &nbsp; &nbsp; 1.79V &nbsp; &nbsp; &nbsp; &nbsp;0<br>Red &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;2.7V &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;0<br>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.
