I don't know if it is the case for your machine, but I believe certain
HP laptops have VT permanently disabled by the BIOS (with no possibility
of enabling it). The reason for it being disabled is that it is
untested, and not supported, by HP. In some cases, a BIOS update may be
available that enables VT on these machines. Perhaps it would be worth
checking with HP on the status of VT on your particular model.
