Powerbook Wakes Unexpectedly

I've searched around the net and this forum and haven't seen any references to this problem.
I'll be watching TV or something and my powerbook will wake up - unprompted by me.
I have a 23" Cinema hooked up to the PB, and usuall the PB's LCD is cracked open - not latched shut while using the Cinema display.
Maybe airport - network related? Like maybe something trying to get in? I have Limewire installed.
Below is the event according to the log:

Hi Andres,
I had the same problem too, one night my powerbook just woke up; I didn't have anything attached to my powerbook. And the screen was all closed, and it when back to sleep by itself...
Heres my log at the time:
Jan 25 09:28:40 localhost configd[86]: SecKeychainItemCreateFromContent err= -60008 ( =0xffff1598) (current= Apple Network)
Jan 25 09:28:43 localhost configd[86]: executing /System/Library/SystemConfiguration/Kicker.bundle/Contents/Resources/set-hostna me

Jan 25 09:28:43 localhost mach_init[2]: Server 0 in bootstrap d03 uid 0: "/usr/sbin/lookupd": exited as a result of signal 1 [pid 4867]
So it looks like its something to do with the airport link !?!
This is about the second time that it has ever happened - so its not that much of a drama for me, but its just really strange !
Anyone know whats going on !?!

Tiger 12" Powerbook - Wake Up Triggers

I'm retiring my powerbook from use as my primary computer, and I'm trying to figure out if I can change the triggers that wake it up from sleep, so I can use it as an iTunes box in my car. (This is kind of a pet-project, plus my aux-in jack in my car is in an inconvenient place, so just buying an iPod is not an ideal solution).
The computer needs to be asleep when the car is off so that it doesn't drain the laptop or car batteries, but when I turn on the car, I don't want to have to access the computer to wake it up. Once the computer is awake, I can control iTunes remotely.
So the trick is:
(1) Make the computer wake up when the car is on, i.e. the AC line is plugged in.
(2) Make it sleep when the AC adaptor is no longer connected to a power supply.
(2) is obviously easy, simply by setting the computer's sleep settings to fall asleep in a minimum amount of time, but (1) is less trivial.
I've been playing around with /Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
which has integer fields with default values:
Wake On AC Change 0
Wake On Clamshell Open 1
By changing wake on Clamshell Open to a value of 0, I can get my computer to not wake up when I open it up and it's sleeping, but changing Wake On AC Change to 1 (in both the Battery Power and AC Power preferences) seemingly does nothing to the behaviour of the computer. I haven't been able to find any info on what this option actually does.
So does anyone have any thoughts on what this bit of the .plist file actually does if not what I'm thinking, and is there any other way to get the computer to wake up from sleep upon plugging in the AC power line?
A second thought would be using the "allow bluetooth devices to wake this computer from sleep" feature, but I consider this not a very clean solution, and will avoid it if possible.
Cheers
Dan

Okay, I figured it out.
Playing with the .plist file was giving inconsistent results for some reason. Instead, use the pmset command in Terminal. Setting acwake to 1 does what you would expect.

Slow bluetooth detection after powerbook wake-up

Hello!
When I am using my Powerbook at home, it is connected to an external screen and I am using it with an Apple bluetooth keyboard and a Logitech bluetooth mouse. My problem is that every time I wake up my Powerbook from sleep, it takes approximately 10-15 seconds before it begins checking up on the bluetooth peripherals, which means that I am incapable of interacting with the OS for ca. 20 seconds - unless I begin fiddling around with the keyboard and mouse on the Powerbook itself.
Is there any way to speed up this process somehow, so that the first thing the OS does after a wake-up is to check on the bluetooth connections?

Seems like an OS X update fixed this. Still a tad slow though...

Powerbook wakes and sleeps on its own

Just the other day my Powerbook started acting really strange. It will goto sleep on it's own, just like that. Usually I wake it up, but it won't always wake up - I click, press keys, hit the power button and get nothing. And then it may eventually wake up.
But it will also get into this cycle, where it wakes up, then goes back to sleep all on its own without the screen coming on. I know this because I hear the DVD drive do it's little clicking thing everytime it wakes up.
The other really odd thing, is that it sometimes has dimmed the screen off, and I have to use the function keys to turn the screen back on. Other times I press the function keys to bring the screen back and I can see very faintly the screen contents, and that the screen should be at full brightness, but it's not. I feel like this thing is posessed.
Now the strange coincidence is that the latch for the screen stopped working the exact same day. Related? I'm not sure. I did have to take it with me, so I put it to sleep by closing the lid and putting it in a tight case, and it appeared to have stayed asleep. I thought maybe the latch controlled the sleep mechanism, but it appears to be the angle the screen is at.
I Thought this was maybe related to that overheating trackpad thing, but my console reads something different. Just "System Sleep" and "System Wake". There is nothing about overheating showing up.
Now the other strange thing, is that the light on the latch button has never really worked correctly as far as I Recall. Sometimes it's pulsing when I'm working, sometimes it's off when it's sleeping, I don't even know the correct behaviour anymore.
Now last thing is that my illuminated keyboard doesnt seem to work. It's as if the computer doesn't know it exists, I press the Funciton keys and nothing happens, and I can't find it anywhere in the sytem prefs.
So I've done the usual, reset the PMU, startup in open firmware and reset nvram etc, Reset the PRAM, system is upto date. I know this thing should go in for service, but it usually takes a bit of time the way things are set up in Canada. This is my only computer and I can't be without it at the moment. Any suggestions to make this machine more usuable for the time being would be greatly appreciated. It can go for hours with no problems, then BAM, it just wont stop sleeping.

I kind of stumbled upon the source of the problem. My Ambiant Light Sensor puts my computer to sleep. If I cover the left speaker grill near the top - where the sensor is I guess - then it puts the computer to sleep about 5-10 seconds later.
Odd.
And now I can wake my computer up by setting off the sensor again, or covering it - but it takes longer. I cover the grill, and then 5 or 10 seconds later the computer wakes up. But the screen wont be on. So I have to put the computer to sleep again with the ALS, and then wake it the normal way (usually the keyboard).
So I guess the solution here (temporary) would be to find a way to deactive the ALS. Is there some file somewhere in the library I could move around? Thanks.

PowerBook wake on Sleep-then kernel panic when re-mounting External Drives

Hey all, I found a peculiar behavior with my PowerBook and my Lacie External Hard Drive. If I wake up my PowerBook from sleep, either by shaking the mouse, or opening the lid- the computer sometimes kernel panics when it attempts to re-recognize my partitioned 250 gig external hard drive. This seems to happen 1 out of every 5 times. The external is already mounted that I can tell upon waking; its just that it seems like it panics when it tries to recognize it again. Any one else experienced this? I've had this problem since I've had my external drive, and that probably dates back to 10.4.2. Thanks!

Hi, Zach.
You might want to try a different FireWire cable, a different FireWire port on your Mac (if available), or contact LaCie, the latter as the enclosure may be malfunctioning. Another potential problem area, although this also usually shows up as spontaneous dismounts of the FireWire drive, is the FireWire drive's power supply, i.e. its power brick, but that seems less likely here.
While it certainly seems like you've isolated the cause to the FireWire drive, you may also want to review my "Resolving Kernel Panics" FAQ. This FAQ includes step-by-step instructions for identifying and resolving some of the most common causes of kernel panics. The FAQ is a roadmap: start at the beginning and work systematically through the end, i.e. the "If all else fails..." section.
Good luck!

Monitor wakes unexpectedly

This problem pertains to my wife's mini (1.42 GHz, 1 GB RAM, 10.4.3), not my own machine.
We recently had a problem where she couldn't use printer sharing to print through the printer connected by USB to my machine. Resetting the NVRAM seems to have cleared that up, but has created a new problem.
Normally we do not power-down or sleep our machines: we let the displays shut off after a few idle minutes, though. Since resetting the NVRAM on her machine, her display (a Dell 19" LCD, fwiw) will periodically activate itself. I haven't timed the interval, but it seems to happen roughly every 3 hours. I've checked the Energy Saver pref panel, and it seems to be set the way I want.
I'm comfortable dropping into Terminal and munging around in there--if that's the quickest way to fix it, I'm happy to try.
iMac G5 2.0 GHz Mac OS X (10.4.3)

Here's another one; you never know!
A number of sleep-related issues can appear after incremental Mac OSX updates, including the inability to properly go to sleep, problems waking from sleep, and having your display go to sleep without your Mac going to sleep. The most common culprit is Bluetooth. Try these tips to fix your sleep problems.
WAKE UP
In System Preferences>Bluetooth, uncheck Allow Bluetooth Devices To Wake This Computer. If you are using a Bluetooth mouse and keyboard, you'll have to wake your Mac by pressing the power button.
FILE CORRUPTION
Your Bluetooth preference file may be corrupt-you'll need to delete it. Turn Bluetooth off, then go to the /Users/user name/Library/Preferences folder. Look for a file called com.apple.Bluetooth.plist and trash it.The OS will create a new preference file when you enable Bluetooth again.
ENERGY SAVER
If you have issues with a Mac or display that goes to sleep at inappropriate times, you may have a problem with Energy Saver. Delete the following .plist files and restart:
-/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
-/Users/username/Library/Preferences/com.apple.systemuiserver.plist--(username is your name or System Administrators name).
-/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
A restart is very important after deleting these plists. After a reboot your Mac will then generate new ones.
In some cases, running MacOS X's cron tasks-maintenance that the OS performs automatically if you leave your Mac on 24 hours a day-can resolve many sleep problems. If you don't want to leave your Mac on, you can use MacJanitor, Yasu, or OnyX free at Versiontracker.com.

PowerBook wakes up when closed

My PB G4 sometimes wakes up (makes waking-up sounds) when it's closed. Sometimes it does this right after I close it; other times it waits a while. Sometimes I can hear it do this only once; other times it does it every few seconds, over and over until I open it. When I open it up the display hasn't waked up (it's still dark). Eventually this waking-up-in-the-dark seems to lead to the OS freezing up. Ugh, please help.

If you use bluetooth devices, the first thing I'd suggest you check would be your bluetooth settings in system preferences. Under settings, see if 'Allow bluetooth devices to wake this computer' is checked and if so, uncheck it.
There's also a command you can enter in Terminal which turns off the computer's setting so it won't automatically wake up when the lid is opened. To wake it, you then just hit a key on your keyboard. If that's the way you want to go, let us know and I or somebody else can get it to you. I wouldn't recommend doing this though unless you're comfortable messing around in Terminal.

G4 Powerbook unexpected shutdown

My powerbook has unexpectedly shut down a couple of times, when in use or not. It restarts ok but I need to reset the date. The battery was recalled last year and replaced. Any ideas why this is happening? Thanks

HP Color LaserJet CM1312nfi MFP Mystery Wake on LAN

The printer wakes unexpectedly, and unpredictably on the network. I cannot determine what, if anything, is waking it. The printer wakes and goes into calibration without any users on the network and without any print jobs. Mystery wake on LAN.

The HP drivers won't load on my 10.10.x (10.10.1 thru 10.10.4) OSX macbook pro. The install says the version of OSX isn't supported even thought I've tried 1.5.0 dmg file which is for 10.7 and greater. I did the math and I believe 10.10.x is greater than any version of 10.7. I also tried HP Easy Scan and it doesn't even see my scanner. Printing works fine, but I scan a lot of paper. Also, I've found that the Mac OSX version of the HP software (when it still worked) creates obscenely large PDF files. I can get around this by opening Adobe Acrobat Pro and re-saving the file as a reduced file size with the same name. I can take a 25 MB file HP creates and get it down to about 300KB or so. I found a way around all this but you won't like it. I've loaded Parallels (installed windows 7 ultimate 64 bit) and installed the windows client in my parallels image. The windows client works fine. Not a solution I prefer, but this is an HP issue not an apple issue .... HP hasn't put out a driver for this printer in the better part of 3.5 years. Lastly, I'm not hooking up a USB cable to my printer/fax/scanner .... what's the point of having a dhcp network capable printer if I have to hard wire to a PC? I've used HP printers since the mid-'90s, but I guess it's time to find a company that supports OSX.

Bluetooth "wake computer from sleep" function always on?

Does anyone know if the "allow bluetooth device to wake this computer" option is designed to be always on even when bluetooth is OFF? I have noticed my computer wake unexpectedly due to a bluetooth signal in the area even though bluetooth was off. The option was selected in the preferences but I assumed when bluetooth is off none of the function are on. Thanks to anyone who could clarify this.
OSX 10.4.11 MacBook Pro 2.16 C2D

I think it applies to both, and I surmise it's because some people have Bluetooth KBs & Mice that need to wake the computer up.

Wakes from sleep by itself

I have a 20" iMac (Intel Core 2 Duo) and an issue appears to have started after the recent software update (not sure if this is the culprit).
My iMac wakes unexpectedly after being at sleep (sometimes after 10 mins sometimes a bit longer). I have NO bluetooth devices attached (and bluetooth is off anyway) and I do not allow bluetooth devices to wake the computer.
I also have the "Wake for Ethernet..." unchecked. I have also tried to trash the com.apple.PowerManagement.plist file and rebooted. And also have run Onyx to fix permissions and run the maintenance scripts.
I just say someone on a different forum post that they too are having this problem with new iMac. Anyone hear of a fix or suggestions as to what may be the cause?

Steve,
Okay more advice. If you go to: http://discussions.apple.com/thread.jspa?messageID=1849881&#1849881
you can read the advice suggested but this one looked really helpful posted by Dale Welsshaar:
This is for a Mac that won't sleep.
First, read things in Apple doc.#25801 on sleep settings.
USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit.
If you've set your Mac to recieve faxes, it may not be able to sleep. It might also have a damaged preferences file.
If you use your Mac for faxing, open System Preferences. click Print & Fax, click the Faxing tab, and uncheck the Recieve Faxes On This Computer box.
If that does'nt work or you've never faxed on your Mac, go to Finder/Hard Drive /Library/Preferences/SystemConfiguration and delete the com.apple.PowerManagement.plist and com..apple.AutoWake.plist files (if your Mac asks, type your admin. password).
If the latter file isn't present in the folder, go to user name(probably your name)/Library/Preferences, delete the com.apple.systemuiserver.plist file, and reboot your Mac.
Hope this helps!
P.S. One member here reported this (Michael Gleason);
"I have had this problem with my IMac G5. It is surprisingly irritating. LaCie's Silverkeeper backup software was the cause. By default it gave itself permission to wake up the computer to check if a backup was needed. Do you have this or a similar program installed which has scheduled activities including wake-up permissions as an option?"
Dave Hamilton provided this link, xlr8yourmac.com, to a member, which addresses failure of deep sleep with some users that updated and added new FireWire and USB cards.
Cheers!

Hopefully this will help you out even more,

IMac mysteriously wakes from Sleep

Hi, I have had this problem with my iMac where when I put it to sleep, it will mysteriously wake up at 7pm, even when no one is home. At first I thought someone at home was trying to get into my computer because every time I came home, I'd find my computer awake, and it bothered me. Then I realized that even if someone was not home, it would wake at that time anyway. What is going on? What is happening, why is it doing that? Should I be worried? I came across this post:
http://discussions.apple.com/message.jspa?messageID=5826698#5826698
Is this what I need to do? I just wanted to make sure before I did something stupid.
Thanks

Well, It's certainly been awhile, and I have forgotten about it as well, but remember it from time to time. I said I would post back, and I am posting back.
Unfortunately, I have had it wake maybe a couple times since I put in that command, but not nearly as "predictable" or often as prior to the terminal workaround. I am unsure if there is a complete fix to this yet myself. If there is, please let me know. It may have been solved in the 10.5.5 update, I have no clue, I haven't had it wake unexpectedly within the past month, so I don't know if the problem is still there or not.
Thanks.

Powerbook freezing

This started happening recently, so I know it's not because of an accessory or software, but my powerbook will freeze every now and then. I am using the powerbook like i normally do, then suddenly, one application lags and then freezes. Then, when I switch to another app, that app also freezes, and then every application freezes on the system. I cannot open the force quit dialog, but I can move the mouse. commandoption+controleject does not cause the computer to shut down. The only way to use the computer again is to manually restart it by holding the power button. If iTunes is playing when this happens, I can still hear the music playing, but I cannot switch songs or pause it. Also, If I can successfully force quit a program, I cannot load another application. Clicking on an icon simply causes it to bounce and it never loads. I am getting tired of this happening and tried reinstalling OS X to fix it, reinstalling OS X did not fix it at all. It sometimes occurs after the powerbook wakes up and the only thing I can do to use it is to restart the computer. I reinstalled OS X by keeping users and preferences. Does anyone else know what is going on or how I can prevent my powerbook from freezing completely?

Can't wake Pismo from sleep - no green light

I have a Pismo G3 all working perfectly with a new harddrive new ram etc, but I have a intermittent problem that when I leave the computer alone it will go to sleep, the screen goes black and the green light on the hinge will pulse up and down as it should, and if I wake the computer it pops back to life as it should, except sometimes when I come back to use the computer the screen is black BUT the green light is OFF, no pluse and the computer is unresponsive and I cannot wake it up? the only way I know it is still on is the fact I can hear the hard drive and in the end I am forced to do a hard reboot????
Any ideas anyone?

Bluefusion,
This is a known problem not only on the Pismo but even some of the later models...powerbook wakes from sleep with a dark display.
One workaround some have found useful: Just close the display and wait until the sleep light indicates normal sleep, then open the display.
Here is an extensive tutorial for wake-from-sleep issues:

HP Computer won't sleep when wrt54g connected

My HP Pavilion m9340f running Vista 64 bit will not enter a sleep mode on its own and wakes unexpectedly while connected to my wrt54g firmware version 4.21.1 10/17/2005.
If I disconnect the router and connect the computer directly to the cable modem, the sleep mode works fine. Does any one know of a way to fix this?
Solved!
Go to Solution.

The problem was an advanced setting in the power plan I was using. The default for the balanced and power saving plan is to "prevent idling to sleep" when sharing media and I had allowed media sharing on my pc.
I went to control panel > power options > change plan settings > change advanced power settings > multmedia settings > when sharing media - and select allow the computer to sleep
I can restore default the settings when I actually am sharing media
