Intel Virtualization Technologies (VT-d and VT-x) not working, but set in BIOS

HP ZBook 15 G4
Microsoft Windows 10 (64-bit)

I (and my team) have brand new HP ZBook 15 G4 notebooks, and Intel VT technologies are set, but not functioning.

 

We have set/unset/reset VT-d and VT-x settings in BIOS, updated to the most recent BIOS of January 23rd, flashed firmwares, and installed all current drivers appropriate to our model.

 

The OS should have no impact on this functionality, but still, we have reinstalled Windows 10 v1709 with latest updates to no effect.

 

I'm out of options other than a new BIOS update.

Have you tried to go into the BIOS then Power Management and uncheck DEEP SLEEP???

 

Save and exit.

I have not, but I will.

 

Why on earth would the deep sleep feature interact with the virtualization features?

Thanks for taking the time to chime in and try to help!

 

I changed this setting and no other setting.  Unfortunately, it had no impact.

I do believe the next step would be to go back to the BIOS and disable Hyperthreading.

 

On some system boards there can be a conflict with Hyperthreading and VT-x both enabled???

 

To disable Hyperthreading Deep Sleep must be disabled first.

I'll test that, but if that's the case, then HP needs to fix that in the BIOS.  That's a workaround, not a solution.  Still, it would be really nice to have an outcome!  I'll update shortly.

Thank you, an excellent suggestion, however, when following the link for my exact model, that BIOS does not currently appear (when things appear at all...).

 

Presently, that download link leads to the result "The requested URL /pub/softpaq/sp85001-85500/sp85240.exe was not found on this server." for BIOS revision 1.17A.

I am not one to apologize for HP but I will say the support sites are going threw changes and has been a little flaky lately.

 

I am using IE and this is what I see when I click on this link.
