I used a Legacy Boot mode to install Windows 7 Pro 64 bit on this HP laptop. I used Win 8.1 and AMD to install all hardware drivers. I updated the system to the latest BIOS version on the HP website. All current Windows updates have been installed. Though I'm basically ready for the apps, I found that no matter what I do, the laptop will not shut down properly. I know that this HP system was built for Windows 8. However, the owner wanted the laptop to have Windows 7 Pro 64 bit instead of Win 8.x. I even uninstalled Win7 and reinstalled it...but no luck. I googled the problem and have come up with no real definitive help. Can anyone direct me to the right solution. I would greatly appreciate you help. Thank you.
