Keeping Mac asleep?

Message #1 - Posted 2008/08/27 - Tim Smith

My Macs occasionally wake up for no reason that I can discern. E.g., I'll be at work, happily working along, and suddenly get a notice from iChat that I'm trying to use it on multiple computers. I'll then ssh to my home server, and from there ssh over to my home Mac (the one that is supposed to be asleep...) and find that it is, in fact, awake. I then do a "pmset sleepnow" command and it goes back to sleep.

Similarly, I'll be at home, and my work Mac will wake up, against for no reason I can see, and I'll ssh to my work server, ssh from there to my Mac, and put it back to sleep.

I thought it might be my wireless Mighty Mouse--maybe a big gust of wind, or a big truck going by shakes my desk a little at home, the mouse wiggles, and the Mac wakes up. Maybe the cleaning lady bumps my desk at work.

However, I've taken to turning the Mighty Mouse off when I leave, and the Macs still occasionally wake up mysteriously (around once every day or so). I usually leave the keyboard on, but I doubt random vibration of my desk would press a key.

Each Mac is hooked up to a UPS (I mean to the data interface of the UPS, not just to power), and the UPS will wake the Mac on a power failure (so the Mac can cleanly shut down), but I see nothing in any logs about any UPS events.

Aside from mouse and keyboard (Apple Wireless keyboard), the only other peripherals on these are:

Home iMac: USB hub with nothing connected
Two Western Digital MyBook drives, via Firewire
UPS via USB

Work Mac Pro:
DVD writer via USB
hard drive via Firewire
UPS via USB

Anyone else see this kind of thing? Any ideas?

Absence of evidence is not evidence of absence. That certainly happens to the two UPS'd machines I have here.

Heh. It's more likely some wake-on-LAN response.

That leaves your house and goes to your workplace when you go home, then leaves your workplace and goes home when you go to work?

I have a somewhat different problem, but maybe they're related. I walked into my house the other day, into the dining room, where my iMac is. Just as I walked in, I heard the start-up "bong" sound". It started up completely without any action on my part. And no, it's not programmed in the Energy Saving options to turn on at all.

Macs are very, very strange. In over 20 yrs of owning DOS/Windoze machines, I have never, never, ever had one start up on my spontaneously! Has anyone else had this experience?

My home network is wireless, and iMac does not support wireless wake-on-LAN (I'm not sure anything does...I get unclear answers when I google).

I'll have to do some experiments. I'm sure the machines have woken on occasion without the UPS data port connected, but that was before I took to turning the mouse off, so it's possible it was mouse jiggling back then, and UPS activity more recently.

But the system log should tell you *something* about what is waking you up. In any case I would strongly suspect some USB device (even just a hub). m.

In over 20 yrs of owning Macs, I have never, never, ever had one start up on my spontaneously, nor has it happened to any of my friends, relatives or clients, and it's not something I've read about in the c.s.m. groups. Why do you posit that Macs in general are very, very strange based on one event?

It may start up automatically if set to reboot after a power cut and the power actually fails (maybe just for seconds).

I'm no expert, but the radio consumes a fair amount of power, compared to the sleeping processor, so keeping _it_ awake is not so efficient.

This is a long shot, but I thought I'd ask anyway...

Do you have the FAX modem enabled? I enabled mine recently when someone needed to send me a FAX. I noticed after that that my Mac wakes up when the phone rings.

I see it all the freakin' time and like the Dock reappearing during fullscreen QT Player playback, I've given up hope of a fix. I don't have a UPS either (power supply in NZ's North Island is very stable).

If you're not part of the solution, you're part of the precipitate.

Nope. I don't even have a FAX modem. No phone lines are plugged into either Mac.
