I have a Hp Pavillion Elite HPE-150uk which i've dualbooted with windows 7 and Snow leopard which i've updated to the latest version.

I have sound, graphics and ethernet working (not sure about wireless yet)

I want to get sleep on it working - i was told i needed to fix my dsdt or something and then reinstall with it prepared on a memory stick? is this along the right lines?

If someone could give me a few pointers at what i need to do to get it (sleep) working i would be very grateful.
