and

worked for my laptop, that is a workaround to allow enabling of VT on bios that do not have options in the menu to do that. In my case the bios revision is R0083N0, so I saw the list by bios revison and look for the VT register (0393).

I needed to do this to solve a problem with VirtualBox that prevented to use more than 1 cpu showing an error VERR_VMX_MSR_LOCKED_OR_DISABLED.
