L502X - A12 BIOS revision with VT-x bug

Yesterday I was trying to boot a VM with VirtualBox and it was returning an error message saying "VT-x features locked or unavailable in MSR". I went to several internet forums and all of them indicating to enable the feature in the BIOS config. I went to my BIOS config and it was already enabled, but the message was still appearing. So I made a downgrade to A11 revision and I could boot my VMs again without any problem.
