Ways in which I attempted to address this myself...
I first re-installed all drivers and updates, including BIOS updates. After that didn't fix the problem, I did a full wipe/re-install of windows 8, and again, updated all drivers from the HP website. This issue happens on both Windows 8 and Windows 8.1. I then did an exchange, and even the new exchange ultrabook is experiencing this issue. HP technicians, there is something faulty with this device. Please acknowledge and address ASAP.
