I agree, HP sucks. I want to replace the wifi card in the future, but I heard you can't, because BIOS is locked and whitelisted.
Anyways, I applied the DSDT. It works wonderfully, sleep and USB 3.0 working great now.
I have 2 big issues though:
1. Audio no longer works. I had to delete VoodooHDA.kext in order to boot up (otherwise there is a kernal panic.) At the moment, the audio shows mute, and I can't change it. (Picture showing it in attachment.)
2. Brightness settings WORK! However, it's weird, there are only 4 levels of brightness I can change. Meaning the slider or buttons don't make a difference until the last 4 squares. (I've attached another picture to show when the laptop is at its brightest settings.)
