Ok, so I thought I would throw this out there in case others found it hard to find in an older thread.
My video was very choppy and I couldn't figure out why. Also, when I would close the lid on my machine to put it to sleep, it would never wake up properly. Either the video came back and the trackpad would no longer work or the screen would just be blank.
THE FIX: Disable USB legacy support in the bios. I also disabled bluetooth to be safe since I am not using it right now, but all of these issues were fixed for me once I did that.
UPDATE: bluetooth works fine. Just disable USB legacy in the BIOS.
