No drivers pertaining to this issue are available as of yet for Windows 10, and I can't get into my BIOS. But my sound entirely went off from my speakers, and all of my hotkeys/function keys stopped working.

I don't know what it did, but my screen darkened and my backlit keyboard turned off, which is normal. I was watching a video in full screen yesterday, and my laptop battery went below 20% and started its 'ultra power save mode' on its own.
