wake from sleep weirdness (10.4.9)
-
RobertB - 09 April 2007
this is odd. I have an iMac core2duo, 10.4.9. I put the computer to sleep manually at night and wake it in the morning with a tap to the spacebar. I've done this with all my Macs for the past three years. This morning when I woke up the Mac was asleep, however, around 9:37 (according to the system.log) the Mac woke from sleep without my pressing anything. Anyone know how that can happen.
The only thing that happened around that time was a phone call I received that went to my answering machine and the caller hung up before leaving a message. Most likely a telemarketer.
Remote wake? Gremlins?

Do you have a modem and is it hooked up? If so, it might have been:
System Preferences -> Energy Saver -> Options -> "Wake when the modem detects a ring"

or if your bluetooth was on then a bluetooth device may have woke it up.

If you had a slight power fluctuation, it is possible the Mac detected this and that woke it up.
System Preferences -> Energy Saver -> Options -> Restart automatically after a power failureBob Harris

Bluetooth and AirPort are both turned off. And I don't think I was in the office that morning and accidentally bumped against the table, jiggling the mouse.

No modem on the core2duo, no.

Would be the case even though the machine (both machines) are connected to uninterruptible power supplies? Separate UPS units, one for each machine. The other iMac didn't wake up, by the way.

That option is off anyway. I have never turned it on.

If it's an optical mouse, small particles such as dust in the path of the optics can activate it.

Just wondering if I heard that right.

I'm not sure I understand your confusion. Please do explain.

Okay, this is just too bizarre. Dust (D-U-S-T), as in "fine powdery material such as dry earth or pollen that can be blown about in the air." What about this are you having trouble understanding? I'm not trying to pick on you, but I just don't understand what there is not to understand.

Do you have any USB devices plugged into it? I have an Epson CX6600 connected to mine. If the iMac is asleep and the printer is on, if I turn the printer off my iMac will always wake up.
I can't remember but I think that the same thing will happen if I insert a Palm into its cradle (also USB). These are all connected to the iMac via a Belkin USB hub.
All of the automatic wakeup's that can be configured are all turned off on my machine as well.
Now this is just supposition, but since the keyboard ultimately ties to the USB bus in the iMac (even if it is bluetooth) and the iMac wakes when a key is pressed, there may be a problem with the fact that ANYTHING making a change on the USB will wake it.
Just a guess.

It seems that any change on the USB bus will wake up a Mac; mice, keyboards, USB sticks and so on.
I don't know if it's possible but it would be nice if there would be a preference setting to disable USB wakeup - or only wake up on keyboard events.
