I've always considered this "feature" a bug
Authored by: sr105 on Jun 09, '06 09:08:01AM

Next up, try this:
1. Work on your laptop with *anything* usb conected
2. Decide it's time to go home for the day and close the lid to put it to sleep.
3. Unplug the power, video, and the usb connections so you can pack up
4. Your laptop wakes from sleep while closed due to the removal of the usb device(s). The only way to remedy this is to open the lid and wait for 10-30 seconds (or crash your powerbook, your choice) and then close it again to put it back to sleep

Does anyone know how to disable the USB wakes laptop "feature"?

Thanks.

BTW I've had my powerbook crashed many times by airport screeners who on their own quickly opened the laptop and shut it again (1-2 seconds). The powerbooks just don't deal with this although they have gotten better with updates.

There is a knowledge base article on how to disable this via the Terminal, I have been told by an Apple store.
You can also switch off Safe Sleep, which makes falling asleep take much longer, via the Terminal. See for instructions here:

OK, pretty straightforward - try disconnecting first power, THEN USB, and then video.
At least on my TiBook, system goes to sleep when DVI video is connected and external power goes off. Consequently, unplugging USB without power but with video does not wake it from sleep.

Cheers,

Power first: yes.

My laptop travels home with me every night, and it gets used as a desktop during the day with the lid closed. On both my older Ti and my newer Al, unplugging the power first before anything else prevents the wakeup. I don't have a MB* to test it on, but I would imagine the behavior is the same--try it out!

Even if you forget (like I do sometimes) and unplug out of order, there's no harm done. The machine might wake up and go back to sleep, but you don't need to open the screen. Within 5-10 sec of you removing the power, if the clam is closed, it should go to sleep.
