Inappropriate Turn-Ons
Filed under (Apple, Cubicle & Campus) by The Cubelodyte on August 28, 2007 @ 03:44 pm

MacBook ProMy MacBook Pro has developed a weird behavior. It spontaneously turns on when plugged in to the power adapter. Each time it’s plugged in there’s about a 60% chance of it happening. It happens not only when it’s asleep, but when the thing has been previously properly shut down.

At first I figured it was the “Wake for Ethernet administrator access” feature, but I’ve since ruled that out; yesterday I opened the lid and waited about thirty seconds. I knew I’d shut it down the night before, and that AirPort had also been turned off, but I wanted to make doubly sure. No sign of life. Next, I plugged only the power cable into the thing, and it started right up, chime and everything. It’s something I can live with, I guess, but I have no idea why it’s doing this, and that’s irritating.

Have you considered you might have a sticky or stuck Power Button?

I have, but if that were the case, I would expect it to just turn on whenever it damn well felt like it, not just when I plug the power in, wouldn’t you think? The battery isn’t draining when it’s off, either.

Have you encountered anything similar?

actually I have , but with a bunch of my Imac G5′ snot a Macbook Pro, although the mac Book pro has had issues bu tmostly with waking out of sleep. I am wondering if you are not reall y off but in sleep mode and have you done this EFI firmare update?

Yep, I have that update. It’s definitely not in sleep mode. I know that because:

  • I carefully and deliberately chose Shut Down from the Apple menu during troubleshooting.
  • If it had been in Sleep mode, I wouldn’t see the grey-screen Apple logo, the throbber, or hear the startup chime.
