Here's the deal: When you put the MBP to sleep while it's in closed-lid mode and you disconnect the USB keyboard/mouse, it will wake up again.

With the PB G4 if you want to prevent that, you can remove AC power as soon as you put the PB to sleep. From then on you can disconnect any USB devices w/o waking the computer. That kind of makes sense, because AC power is required for closed-lid mode to work at all. Unfortunately this trick no longer works on the MBP: If you sleep it, then disconnect the power and after that USB it'll still wake up. It then takes a few seconds for it to discover that there's no power connected (I have no idea why this isn't instantaneous) and then it will go back to sleep. Thanks to hibernation this takes a lot of time.

So, is this new behavior thanks to the Intel chipset or is this just a buggy implementation that Apple could/should fix with the 10.4.7 update? And for the time being, does anybody have a good workaround at hand? All I do is just not sleep the MBP at all. I disconnect USB, power and DVI (in that order) and it goes to sleep once it senses no AC power connected. I'm just wondering if that's actually really the way it's supposed to work now.

i just wish i could get mine to fall a sleep and stay that way. it wakes at random... my ibook never did this but i heard the PB G4 did.

i that there are definately some issues here with regard to the sleeping

[OT]I never had a Mac just wake up for no reason at all. Be sure to check BT devices, badly seated batteries, flaky power connectors, unstable AC current, third party hardware/PCI/PCMCIA cards, etc.[/OT]

That said, I'm not saying this must be a bug. It could also be a change in default behavior. It's actually what I'm trying to find out in this thread.
