And yes, I'm pressing the keys immediately, both from a restart and from a full off condition. In researching this problem; I got a PDF of the Apple troubleshooting and disassembly guide and from what I can discern from it, the sleep state is controlled from an IC chip called PMU99 and I suspect this IC is my problem; however, the book is not clear on where this particular IC chip is mounted. It could be on the Power Manager circuit card, the sound and power control card or the main logic board. I've eliminated the Power Manager board because I was able to try a replacement card to no avail. That leaves the sound card or the logic board.
