Hi! Any way to unlock this laptop? I need to use a PCI Express Riser in my laptop, but the laptop turns the screen black. So I need to enable hidden advanced options to setup-configure that stuff. Thanks if you help me! 
The laptop uses the sp65659.exe flash bios installer from HP, so my BIOS version is F.6D Rev3.5
