If I shut down, it will not turn on unless I reset the PMU. Can I
replace the PMU?
If so, where is it?
Battery replaced. Checked ram. Checked cards. Checked cables.
Checked power supply.No. I don`t want
to give this to Apple for repair. I want to troubleshoot and repair
myself. I realize
the opposition from Apple, but where there is a problem, there is a
cogent solution.

Some PCI cards don't support Sleep, so if u haven't checked them, I
would start there.
After you reset PRAM, does it Shutdown and Startup ok? Maybe its just
after u try Sleep, and fails, it won't Startup properly.
How about USB devices? Any attached? Flaky?
USB KB and Mouse good? tried another one?
