The business support site has been down for 18 hours or so.
HP is aware of the issue and hopefully will get the problem resolved as soon as they can.

HP has released a new consumer notebook with the same hardware as yours and you can use all of the software and drivers from this model except the graphics and audio.
Graphics:
Audio: Accept the agreement. Download and install the second driver on the list.
