it seems the powerbook does try to go to sleep but Tiger won't allow it, anyone know whats going on?. Any help is appreciated, thanx in advance

Well, if you are sure its a warranty issue they will not charge you once the issue is resolved. But from what you have said it seems to be software related. I am at a loss what to suggest (sorry). The only last thing I'd say to check is the following:
1) Make sure your folder actions are off in the Finder. Control click on desktop and the menu should read "Enable Folder Actions." If it says Disable I'd say try it.
2) Try logging into a new "clean" new user account (after logging out of yours) and see if the machine will sleep then. If it does look at the StartUp items for your user.

My i7 macbook pro suffers from insomnia

My old C2D macbook never slept, although I had the energy settings set to sleep after 10min of inactivity.
I recently bought a new i7 macbook pro and used the migration assistant to transfer the settings to my new laptop. I soon realized that it also suffers from the same disease, so I guess there is a setting or preference that was transferred and is causing the problem.
I originally suspected that dropbox is the problem, but I have the same symptom, even when dropbox is not running.
Can anybody help me identify what the problem is?
Thanks a lot!

Have you called Apple technical help? I had a few issues recently that didn't even involve Apple but it was software allowing me to use external hard drives with no partitions on Mac and PC. It was 3rd party software and they figured it out as well as giving me all the sites I needed to get it all working. I have had other questions as well and they seem to work on it until it is figured out.

IBook suffering from 'insomnia'

My iBook is no longer going to sleep when the lid is closed. I haven't changed any settings on my computer...the latch is still working on the lid... It just happened yesterday for the first time so I turned it off before bed, hoping the reset would help. But alas, today still no luck...

Katherine,
It sounds like your reed switch isn't working. If you'd like to read more about the reed switch, check out this link:

Disabling the reed switch produces the behavior you are seeing:

So it looks like this is what happened to your iBook.

Powerbook won't sleep automatically

Hi,
im reposting because no one replied to my initial post, my powerbook recently stop going to sleep on its on unless i do it manually. Every other energy saving settings works normally the display sleeps after a while but not the computer itself. Does anyone know whats going on?
Any help would be appreciated
cheers

Hi El Pres. --
I'm not sure here, but three things come to mind, but first two questions of my own:
• First, when you say the PB won't go to sleep unless you put it to sleep manually, do you mean that it just won't go to sleep when you close the lid, or does it also fail to go to sleep with the lid open after a set amount of time as well?
• Second, just so I'm clear, when you say you put the PB to sleep "manually," you mean you go to the Apple menu, select sleep and click, right?
Now, here are the only things that come to mind, in no particular order:
• First, you might try setting up a test account, separate from the one you normally use, and log in to that account and try putting the 'Book to sleep by means other than manually -- first by inactivity, using energy saver settings, and another time by closing the lid. See if either or both work when logged in to your test account.
• Second, you might try resetting your Power Management Unit. Instructions on how to reset your PMU can be found here: http://docs.info.apple.com/article.html?artnum=14449
• Third, and this is the one I'm least hoping is the case, but it unfortunately may be worth thinking about: if your PB does go to sleep after a set amount of inactivity via as per your Energy Saver settings, but does not go to sleep when closing the lid, you may have a hardware problem related to the lid's latching mechanism. WIth my 'Book, it's only when the lid has firmly latched, will the unit enter sleep mode.
Oh, yes, I forgot to mention: throughout all your tests of the computer's sleep mode, keep an eye on the little "sleep light" on the latch button and make a note of when you see it pulsing as it properly should and when you do not. This information may help you, us, or, if need be, an AASP or Apple tech, better understand what's happening inside your machine.
Post back if any of the above yields further useful info, or if you learn more otherwise.
Good luck.

Powerbook won't wake up from sleep mode

Contrary to all the problems posted here of PBs unexpectedly beeing sent to sleep, my PB occurs to have a contrary problem for which I couldn't find a solution for.
When it is in sleep mode I can't awake it, neither by opening the lid nor pressing a key. I have to force shut down it by holding the power button and then it can restart it from save sleep aka hibernation. Furthermore the indicator light does not pulse but glow constantly when in sleep.
I tried to reset the PMU and the NVRAM but nothing seems to help. After resetting both the sleep and wakeup process will work fine one time, but really only one time. Upon next sleep (re-)activation the odd old problem occurs.
What could I try to get it properly working again?
Thanks in advance for your help - and sorry for my rusty English.

My own PowerBook has, on very rare occsions, suffered the same problem. As it happens so rarely (perhaps less than six times in three years) I have not been able to troubleshoot it.
However I have read on previous threads that some people had the issue resolved when Apple replaced the logic board for them - but I don't know if that was a definitive fix.

Powerbook won't sleep if USB mouse, printer attached: is there fix?

Hi there,
Thanks to someone, I now know that my powerbook won't stay asleep more than a couple seconds, because I have various USB items attached (mouse, printer, Wacom tablet). I've been having to unplug from the USB port, if I want to put my computer to sleep.
This seems a little ridiculous to me, so I figure there must be a third-party app out there that fixes this issue. Is there? Or is there some other way to fix this, without having to unplug?
Thanks,
Malcolm

That sounds like a good idea. I've just tried it and it did nothing but i've found info on the following page that has a different set of keys. It did restart twice as described but the problem is still there:

Thanks for trying though... Any other suggestions?

Powerbook won't sleep after OS install and update

I replaced the original hard drive with a new drive, installed OS 10.4 from the boot disk, updated to 10.4.11, replaced original apps and user folder via Carbon Copy Cloner. Machine runs great, but won't Sleep, either from Apple menu or closing the lid, wakes up in 1-2 seconds. Had no problems prior to swap.
Airport and Bluetooth are off, nothing plugged into the port. Trashed bluetooth.plist and restarted. Checked Energy Saver, set to "drive sleep when possible". Nothing new showing in StartUp items, or Activity monitor. Same whether battery or plugged in.
The only diiference is that I typo'd my user name. I created a new Sys Prefs/Account, then deleted the old account. I've run Apple Disk Utility Repair/Permissions amd Onyx maintenance. Nothing scheduled to run in CCC or Onyx.
Any advice is appreciated!

Thanks BGreg,
I did Software Update via WiFi. It took multiple passes, as Java would install, Software Update would recheck, and then download the next version. Took about 5 passes, with 2-3 restarts to have everything updated vai S.U.
I used a generic Tiger disc as the boot disc.

My G5 won't go to sleep

Hello,
Ever since i installed the new combo update, my G5 won't go to sleep when it is scheduled to sleep. I have it set at 1hr. It always used to go to sleep before i installed the combo update. Anybody else having this problem? Any solutions?
Thanks for any help,
John

No, I run it on an Intel and a PPC Mac and have no sleep issues (I use Combo Updates though).
This is for a Mac that won't sleep.
First, read things in Apple doc.#25801 on sleep settings.
Here is Apple doc.#303698 with their tips.
Mine follow;
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 receive 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 Receive Faxes On This Computer box.
If that doesn't 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!

"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.

My eMac won't go to sleep

My eMac won't go to sleep automatically. I have to do it manually. I've tried reseting energy saving to default. No change. Also my screen saver doesn't appear. The screen will just go black. So I endup with a black screen while the computer just keeps running. It is very annoying. Anyone had the same problem?

Check the printer queue!"

MDD G4 (Dual 1.0ghz) Won't go to sleep...

Hey all,
I've got a weird problem where all of a sudden, my G4 MDD won't go to sleep! it's been working fine, and I haven't changed or installed anything in the last few weeks. Selecting sleep from the apple menu doens't do anything.
I thought it might be a pram problem, since my clock was always getting messed up lately, when I rebooted, it would always say it was out of synch and at a really old date. This problem is now fixed, but I still can't put the computer to sleep.
Could this be a battery problem? Is there any way to check?
I'm running 10.4.8.
Any thoughts would be appreciated.
Thanks!

G5 won't go to sleep, plus front fan clicks

I am working on a friend's G5. It won't go to sleep. The monitor does, but not the CPU. I have upgraded the firmware, to 10.4.10, zapped the pram, corrected permissions. Just at a loss. Any suggestions?
This computer worked fine at work where she had it originally, but when she shut it down and took it home, it has insomnia. Also, one of the front fans sounds like it is scraping or hitting something. It is not a loud noise and the fans still work, just annoying to her since it won't sleep. (Sounds like my one month old).

-*, in your case,
First do a use Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk. This should be done before every update.
Then,
Some, in these forums, have had luck fixing sleep issues downloading the Combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
Yours would be the 10.4.10 Combo PPC update. Others reading, download the combo update that applies to you! Please do the above in order.
If you still have issues work thru the following;

MacBook won't go to sleep when connected to external monitor

Dear all,
I have a MacBook connected to an external monitor via DVI to HDMI adapter. The MacBook is also connected to the power adapter and to an external aluminium Apple keyboard and a wired Mighty Mouse via USB. I use the computer with the lid closed. The problem is that, even though the system preferences are set to put the computer to sleep after a few minutes of inactivity, it won't go to sleep if it's connected to the external monitor, regardless of whether the monitor is on or off. Is this normal or is there a malfunction? If the latter, any ideas how to solve the problem?
Best regards,

Hello again, JasonFear,
Thank you for your help and I apologise for not having reply earlier, but I was trying and checking your suggestions. What I have done is safe booting my MacBook, and the problem disappeared, so I started tinkering with the login and the preferences. In the end, I replaced the preferences folder using a month-old version in Time Machine. And now, I don't know if my original problem was not external-monitor related or it is just that I have a different problem because, at the moment, the problem is like this:
My MacBook refuses to go to sleep by itself when iTunes (version 9.0.3)is open. However, I can make it go to sleep using the Apple menu, the keyboard or the remote control (pressing and holding the play button).
It doesn't matter if it's connected or not to the external monitor.
I've checked this page
http://support.apple.com/kb/HT1776
but the solution is not there. When iTunes is open, I make sure there is nothing playing or downloading (no song, no podcast). iTunes checks for new episodes of podcasts every hour, and the computer is set to go to sleep after a few minutes of inactivity.
Any ideas?
Best regards,
Jobuscon

MacBook won't go to sleep

I have issues putting my macbook to sleep in this configuration:
1. lid closed
2. connected to an external LCD monitor (via VGA adaptor)
3. power adaptor attached (100% Charged)
4. external keyboard and mouse (via USB)
Ive tried all the suggestions in the `If your Mac won’t go to sleep` Help file including:
1. “Put computer to sleep when it is inactive for” is not set to Never
2. deselect “Wake for Ethernet network administrator access.”
3. deselect any services you aren’t using (none selected)
My macbook has no issues going to sleep when no cables are attached and I just close the lid.
What happens instead is the screen goes black, I wait for the indicator light on the right to pulse, it doesnt, and my macbook wakes up again.
Any assistance with this issue would be great!

ok - it looks like it completes hibernating and sleeps and then immediately wakes up. I cant tell from the log files what is causing it to wake.
I do find the `network traffic reduction measures in effect` out of the ordinary and AppleTalk starting up and shutting down frequently suspect without researchin further...

My MacBook Pro won't go to sleep when I close it

1. My MacBook Pro won't go to sleep when I close it and my fan runs all the time. When I go to my activity monitor it show my mail program runing at between 98% and 153% of CPU. I've called Apple Service and they can't help. HELP!
