I tried editing the DSDT of my system, but it turns out I can't use it because it's so screwed up. There are so many errors returned by MaciASL when compiling it unmodified.

I tried downloading an ACPI kext for my exact laptop model from insanelymac, and that fixed my sound adjustment issue with the keyboard, but not the brightness adjustment. There is no brightness slider under display, and the monitor has one resolution to pick from, which is the one I forced. I am not using a DSDT. Is that why I cannot find a solution to this?

I also have problems with the usb ports. When I plug in a usb device while booted into Mavericks, the laptop freezes after a few seconds within plugging in the usb. Is this a problem with the IO storage controller?

One solution would be to go into the bios and see if there are any options you can change for the video card, such as disabling power savings, or you could download a GPU overclocking tool like AMD Overdrive and see if you can change the clock speeds that way. If neither of those work, try editing the vbios to force clock speeds.

I believe disabling SLI from the Nvidia control panel will do something similar to what you want, but this only causes the ultrabay GPU to downclock and not turn off completely. You cannot completely turn off the ultrabay GPU unless you physically remove it from the system. Once you do that, go into the bios, and you will be able to disable the internal Nvidia GPU in order to use the iGPU by itself to save battery. I don't think the modded bios will allow you to turn off the PCIe bus, I don' think there's any bios that allows you to do that.

It depends on if the drive is broken or still working. As av24man said, you can use another mac to get the data off your hard drive if it still works. If the hard drive is broken, try sticking it in the freezer for a few minutes, then take it out and bang it on a desk. This will dislodge the reading head from the platter.

I've gotten pretty much everything to work on this y510p ideapad hackintosh I've made. Everything except the brightness controls. For some reason, I can't change the screen brightness while booted into Mavericks. Anyone have a solution to this?

You may have to install some kexts to get your graphics card working. As for opencl, that's a framework for writing programs that execute across multi-core processors. It also contains a language for writing kernels and was originally developed by apple.
