I just upgraded from Windows 7 to Windows 8.1 Pro. Some manufacturer's just don't include the option in the BIOS. In conclusion, unless you desperately need virtualisation enabled, it's better to leave it as it is.
In the end the only option was to flash a BIOS which has the options unlocked, but I decided against it as it was too risky- IT MAY BRICK YOUR COMPUTER AND RENDER IT UNUSABLE.
Go to Device Manager (right click on My Computer, choose Manage and then find Device Manager in the left panel), or right click on Start Menu for Windows 10 and select Device. I ran into the same situation too - I have an Acer laptop and in my BIOS there's no option to enable VT-X (along with many others). In order to manually update your driver, follow the steps below (the next steps): 1. Unfortunately this is the only way since your manufacturer did not add the option to enable virtualisation in the BIOS. Look for your computer make and model + BIOS version and follow the instructions there. If your computer does supports it, and you have checked every option in the BIOS, and your BIOS is the latest version (go to your manufacturer's website), then the only option is to flash a BIOS. Alternatively, you can download and run the Microsoft® Hardware-Assisted Virtualization Detection Tool. You can do that at (I'm assuming it's Intel, look for your CPU and check if the VT-X feature is present).
HP techs are kinda dummies but at least they try to help,can't fault them there.Firstly you need to check if your computer supports virtualisation. I HEAVY GOOGLED this problem and found nothing.
I ask you fine folks here, is there anything else I can do to bring her keyboard back to functioning like it did when we got her PC without having to nuke it. my wife won't let me nuke windows 10 because that would involve reinstalling things and setting up her pc in a way that fits her computing again. However in this instance it didn't do nothing. Upon bootup the keyboard reads as a standard PS/2 keyboard,the FN keys STILL don't work and the backlight won't shut off! Frustrating! The only thing I tried doing was Disabling the "Action Center" in the bios because I read that helped a few people out there experiencing the same problem.
The step she took was "Uninstall and Reinstall" the keyboard under "Device Manager" then she rebooted the machine. I have an HP Envy dv6-7000 that someone replaced the motherboard in. So being the novice she tends to be on PCS she tried troubleshooting it (Probably not a good idea ha,ha) Now,my wife is pretty knowledgeable with computing but not in the advanced sense. Well, my BIOS is by American Megatrends, and I discovered that they have a set of. The other day my wife booted up her laptop and noticed her FN key wasn't working. I don't use her laptop but preform maintenance on it when something goes wrong,but this one has me horribly frustrated! The only specs I am aware of is it has a Intel Core i7 and 16 gb of ram.
