HP Envy 17 Sleep Issue - Instant Wake

[mnfesq]

I have an HP Envy 17t-3200 CTO with the Intel H76 motherboard and an i5 3210M CPU. I'm running 10.8.3 and it is very stable. I would like to be able to improve its ability to sleep. Currently, I can get it to sleep if I unplug it from AC and put it to sleep. I can replug it back in while sleeping and it stays asleep. However, if I try to put it to sleep while it is plugged in, it wakes up instantly and the Wake Reason is the USB hubs, ECH1 and ECH2. I can't see anything in my power settings (pmset -g) that would explain this. I have used the Ivy Bridge ECHI patches without success. Any ideas?

I gave this a shot and, while it compiled and booted ok, it still woke from sleep instantly. Wake reasons were still ECH1 and ECH2. When I used the power button to enter sleep, the powerbutton was also a wake reason.
