New way to wake a Mac from sleep

Message #1 - Posted 2012/09/04 - dorayme

Wait till it's about 3am and its cold, you need to get up for a minute, you switch a fan heater on to take the edge off the shiver while up for a minute. My Macbook woke up and lit the room, charger was attached. Seems a little surge is enough. My MB is light sleeper like me except its thing is electricity, with me, it's bladdericity.

My Mac has woken up after connecting my phone to its charger, which has no connection to the Mac except for being plugged in to the same power strip.

Interesting, that would be the lightest of surges.

It seems to be hyper sensitive. Even though I always put it to sleep at night, at least once a week I find it awake in the morning. The system log indicates it wakes up at random times. I haven't figured out what causes it.

Are you sure it isn't from a tiny vibration to the mouse caused by the physical motion of the plug-in?

Yes, I have never quite worked out all the causes. I am pretty sure of power surges in this particular new location I am in being one of them. I disconnect the HP printer USB cable when not printing as it showed up as a possible factor in logs ages ago.

When I log out and the login screen comes on, I go to the sleep button with blue tooth mouse and it goes to sleep straight away but quite often wakes back up again. The second go seems to take, giving me time to go out and letting the computer worry about itself from then on (it would sort of obey default or admin energy prefs then I guess).

I went for years with a Powermac QS basically hardly ever resting the machine or HD, just the monitors. But those old models with USB2 added cards were notorious for not wanting to sleep. The 2002 QS is still going well and so are the HDs in there, not that I use them much now.

In my case, I thought of that, except it is a battery bluetooth.

You can wake a sleeping computer simply by clapping "too close" to the mouse. The same can happen due to close thunder, large trucks driving by, electric garage door opener, toilet being flushed, etc. Anything that can cause "enough" vibration to "move" the mouse.

Wireless interferrence can also cause sleeping computers to be woken up. Your neighbour making a midnight snack in their microwave could wake your computer up if the homes are too close.

Just another reason to shutdown the computer if you really want to it to be off. At the very least you should set the computer to logout after an certain time limit. :-)

Waving my mouse about violently will not wake my Mac up unless the button is clicked, so I doubt it. And no, I don't have a cat or any other pets.

Well, I didn't really think about this till now, but when my iMac goes to sleep, only a key press will wake it up. Mouse has no effect.

However, when my Macbook is asleep, it wakes up at any bump of the table, and even when a heavy person walks by.

It also wakes up when I turn off the Bluetooth mouse.

And maybe the fact that it's Bluetooth explains the other.

Wireless mice and keyboards also go to sleep when not used, whereas a wired mouse is still drawing power even when the computer is asleep.

I only Bluetooth devices I have are my Apple keyboard and mouse. But at any given time my Mac can see anywhere between three and eight other devices that belong to my neighbours. Maybe they are waking my Mac up. But I don't see why they should, since none of them are paired/connected/whatever.

Do you have a cat?

My cat has woken the iMac in the middle of the night while on its various patrols to keep the house safe from whatever it imagines is a threat (or a snack - come to think of it we don't have as many spiders as we used to have ...)

I've dissuaded her from getting up on tables, generally, and so I've found my Mac awake at 0300 less often...

Is a trackpad sensitive enough that a spider would wake the Mac? I know my trackpad needs only the gentlest of touch to wake it. Are trackpads dependent on pressure, capacitance ... what?

What I described earlier, being logged out, the computer asleep, mine at least, normally won't respond to my bluetooth mouse. Only a usb mouse or the trackpad or a keystroke will regularly and reliably wake it.

There are settings in Sys Prefs for Bluetooth and one of these is a box to choose whether to allow a Bluetooth device to wake the machine. Whether this is an 100% reliable setting is another question.

But it is the wired one that can't wake up the iMac on the desk, while vibrations can wake the Macbook on the same desk. Might not be the mouse, although physically turning off the BT mouse will also wake the Macbook.
