Ok, you should be able to get the drivers for the sound, video, chipset, and network from that page.
As for the repairs, dont do a clean start, instead run the repairs in safe mode with networking. That has been the best way to keep 3rd party programs from getting in the way.
As for doing a proper power reset, well looks like you wont be able to. I hate when they put batteries in that you cant take out. Its like the people who designed it have never heard about properly resetting hardware.
See what happens when marketing helps design something lol
