G4 MDD won't go to sleep

Got new monitors, nice! Now,the Mac won't sleep. No, I don't think it's the new monitors, in fact, I was amazed how quickly the mac went to sleep at first. I did, however, have to press the on button on the CPU to wake it up, a key stoke didn't do the job. What could be stopping my Mac from going to sleep? At times, I can't get it to shut down either, without pressing the CPU button and holding it for along time.
Please help poor old Mac.

Hi Patt-
Many factors can cause sleep disorders.
Common causes are USB PCI cards, active external hard drives, active internal processes, corruption of the hard drive directory, corruption of the PMU.
Disconnection or powering off PCI connected USB devices usually clears that problem.
If the new monitors have USB connections, try without them connected.
Allowing drives to spin down or ejecting them prior to sleep will keep the drives from interfering.
Spotlight is a process that can interfere with sleep (among others). Checking active processes with Activity Monitor can help ID the culprit.
Active internet connections or network settings can also interfere.
Boot to the OS install disc and using Disk Utility to "Repair Disk" on the boot drive is always beneficial, even if it doesn't clear the problem.
DiskWarrior is better.
A reset of the PMU can clear corrupt power management settings which interfere with sleep.

Power Mac G4 MDD won't wake from sleep mode

I have a Power Mac G4 MDD 1.25GHz with a 15" Apple display and running 10.4.
I can not wake the computer up from the sleep mode. It will not respond to the mouse moving, a mouse click, a keyboard key, the power button on the display or the power button on the computer.
The only thing I can do is force the computer off by holding in the power button (on display or computer) and restarting the computer.
The computer is set to go to sleep after 1 hour of no use (or the issue happens if I put it to sleep).
Any thoughts would be great.

This is for a Mac that won't sleep.
Here is KB article HT1776 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!

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!

G4 MDD won't sleep

Hi everyone,
This problem began when I was running Panther, and today I upgraded to Tiger, but the problem persists.
My computer won't go into sleep mode. When I try to put it to sleep, the display shuts off, but the computer is still running. At that point, I try clicking the mouse and/or keyboard, pressing the power button, trying various combinations of control/escape/apple keys to execute a hard quit, but nothing I do gets the display to come back up or the computer to power off or restart. So I'm forced to cut the power to the CPU and then power it back on. I know this is terrible for the computer, and I hate to do it, but I don't really have any other option.
When the problem first appeared, I could at least get the computer to shut down, but now it won't even do that. It gets to the spinning wheel screen and just hangs there, and again, I have to resort to cutting the power.
It's crazy to have to go through all this, and I certainly don't want to damage my computer. Does anyone have any experience with this sort of problem, and/or any ideas for a fix?
Many thanks!
Kate

First,
Try using Disk Utility to repair your startup disk (hard drive) as shown in Dr.Smokes Resolving Disk, Permission, and Cache Corruption. All those hard shutdowns can cause directory corruption.
If that didn't fix it, read on:

My macbook pro won't go to sleep when I close the lid

I've been having this problem for a couple of years now, and it's getting pretty annoying.
I got this MacBook Pro in April of 2011. Otherwise, it works great. It goes to sleep when I go up to the apple menu and select "sleep." BUT, when I close the lid, it stays on. Heaven forbid I don't have it plugged in, because then the battery will be shot! It also won't go to sleep automatically when I leave it for a long time. Yet another potential battery drain.
How do I fix it so that it goes to sleep automatically when I close the lid and when I leave it alone for a while?
In Energy Saver, I have checked all the boxes necessary: "Put the hard disk(s) to sleep when possible" "Wake for network access" and "Automatically reduce brightness before display goes to sleep."
Am I missing something here, or does my computer just have a defect?

I had the same issue.
I used an external monitor but all of a sudden when I closed the lid my Macbook Pro did not go to sleep!
I solved the problem with a SMC reset.
Try to do it...

Won't Wake From Sleep

I held off from posting this until I'd scoured the boards looking for ideas, but I'm totally out.
Every since I updated to 10.4.8, my MacBook Pro won't wake from sleep. I've tried resetting the SMU and PRAM, enabled and disabled bluetooth device wake from sleep, and installed the latest EFI Firmware update that was just released. I've now narrowed it down to the 10.4.8 and a change in how it handles Expresscards. If I have my NitroAV FW 800 card plugged in during a session, it seems to prevent the MacBook from going to sleep properly. According to various Console messages, the PCI device prevents the computer from going to sleep, and /or places the computer into System Doze instead, from which it won't wake. The sleep light stays fixed and steady, only disappearing if I press the power button (it only reacts to the power button). From there the screen remains dark and all plugged in device fail to respond. I can hear the drive spin back up.
It reacts the same whether or not I eject the card before putting the computer to sleep. This behavior was not present before installing 10.4.8 and having fallen back on a back up of my 10.4.7 install, can say it's not present in the older OS version. I was hoping last night's EFI firmware update would deal with this, but after having installed it and 10.4.8 anew, I'm having the same old results.
If anyone has any new ideas or can direct me toward how I can make sure the folks at Apple see this, I'd greatly appreciate it.

My macbook won't go to sleep unless I use the Apple icon on the task bar

I have a late 2008 macbook unibody (old i know, but its still kickin)
The computer won't go into sleep mode with the lid closed or if I hit the power button. i have to manually do it with the apple icon in the top of the screen.
The ambient light that blinks while in sleep doesn't light up when I do this either. Its been like this ever since Lion, Mountain Lion and now Mavericks.
I've done a clean install of Maverick on a brand new HDD. No change.
*I have modified the computer since I've owned it.
Upgraded from the OEM 2GB of memory to 4GB which is the max for my model.
It didn't come with the illuminated keyboard so I bought the backlit one and installed.
I also had to swap the motherboard to do this since my original did not have the backlight connector.
**Note the old motherboard also had the same problem with the computer not going into sleep. So I don't believe its a hardware issue.
(yes I plugged everything in and seated everything in a appropriate manner, I build custom PC's for friends all the time so I kind of know what to do and what not to do).
I have checked my sharing preferences and they're all unchecked as this is a fresh install of mavericks.
Everything else is all set to system defaults.
Any suggestions/insight?

Check System Preferences > Energy Saver
Select: Put hard disks to sleep when possible
Then click: Restore Defaults

My display won't go to sleep

I just recently upgraded to the Mountain Lion OS and now my computer won't go into the screen saver (set at 10 minutes) and the display won't go to sleep (after 15 minutes). It is on all the time. Any suggestions?

Same issue in ML (sorry for continuing this thread here).
Please let me know if you figure this out. I have tried SMC/PRAM resets, disk permission repairs. Nothing.

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...

Hi David,
- Have you tried any troubleshooting steps?
You may try the following steps:
1. Reset SMC as per the following article http://support.apple.com/kb/HT3964?viewlocale=en_US. If this does not resolve the issue then go to step 2.
2. Navigate to Macintosh HD/Library/Preferences/System Configuration and remove a file called powermanagement.plist (drag it to trash, might prompt for a password). Restart the mac thereafter. If this does not resolve the issue, boot to safe mode as per http://support.apple.com/kb/ht1455 and check the issue there. If it works there, you will have to remove the following files to check Macintosh HD/Library/StartupItems, HD/Library/Caches and then restart the mac.
Let me know if this works.

My MacBook Pro won't go to sleep whenever I close it. How do I fix that?

I just got it back from getting the keyboard replaced due to a juice explosion, and now it won't go to sleep when I shut it. I've altered the energy saver settings to try to get it to sleep, but it just won't do it when it is closed!

Is your laptop sleeping with open screen? Are you able to make it sleep over the ON/OFF button?
Often these strange sleep porblems are also due to a software conflict. So try to create a new user, switch to this account an see, whether the problem persists. You could also try to restart by holding down the SHIFT key, to disable the start items. Does it sleep?
What is using your CPU? Is there something running and using mor than 80 % of your CPU? (Look into Activity Monitor).
Look into the Console (Applications > Utilities) and look into the error log, specailly after choosing the "Sleep" over the Apple-menu or the Power button. What are the errors?

MacBook Pro Won't go to sleep when I close it

My computer won't go to sleep when I close the lid. I tried restarting which fixed it at first but then a few hours later it started doing it again. This has been happening for about a week now. It only goes to sleep when I manually select it from the Apple menu. Any thoughts or suggestions?
Thanks,
