IBook will not sleep

Since upgrading to Tiger, now when I close my iBook lid, the computer will not sleep. The only way I can get it to sleep is to unplug all peripheral devices (including my power cord) and select sleep. It used to sleep automatically on closing. I've tried adjusting my energy saver choices in System Prefs, unclicking receive faxes in System Prefs, and all other funky suggestions I found online but to no avail-it will still not sleep when I close the lid. Does anyone have more suggestions? I travel a lot and like to store my computer in sleep mode in my computer case, but now it runs instead and wears my battery down!

Hello,
Unfortunately, I think your problem is hardware related. From your logic board, running through the right hinge of your display, there is a cable that is connected to your display inverter board, and a device in the display, called a reed switch. This cable contains several wires (6). The reed switch is a device that, when nearby a magnet sets the computer to sleep. The magnet is positioned underneath the keyboard so that when the lid is closed, the computer is set to sleep. If a wire is broken (most likely in the hinge), you may have one of several problems. For example, your sleep function will not work. Or, as in my case, the backlight does not work, so the display goes dark. Only time will tell which cable will break first, so in your case it was the one to the reed switch.
What you need is a 076-1073 PCEBA Reed Switch with Cable for
dual USB white iBook. It is an original Apple part and can be purchased from http://www.smalldog.com for $20. However, replacing the cable is somewhat tricky, but not impossible. I did it without previous laptop surgery.
There is also another discussion thread on the backlight issue. It has some good links.
This is what I think is the problem.
Good luck

IBook will not sleep with clamshell open -

I have been using this iBook for years with no problems until the system updater updated to 10.4.9 on 4/24/07. Ever since then the iBook will not sleep on its own, I have to shut the clamshell or use the sleep command from the Apple menu.
I have tried disabling all sharing (file printer internet).
I have reset the PMU multiple times.
I have tried several different settings in the energy saver panel.
I have used "sudo periodic daily weekly monthly."
I have verified and repaired permissions.
Here is my console log from today:

Looking back several days seems the "lookupd" hangs up quite often and the Sound assertion always fails.
Any help/suggestions would be greatly appreciated.

Does this happen when running from the AC adapter or from the battery, or does that not matter?
Try booting into Safe Mode. This will take quite awhile longer than a normal startup because it does a file check and repair of the hard disk.
You will see your normal desktop. Once completely started up in Safe Mode, restart normally, and go to Applications > Utilities > Disk Utility. Select the named boot volume in the left sidebar, ("Macintosh HD" unless you've renamed it). Repair permissions on it.
Recheck the settings in Energy Saver in System Preferences.
See if a little hard drive maintenance helps.

IBook will not sleep when lid closed

Hi,
I recently had my Hard Drive replaced, the old one died. It was all covered by AppleCare and the repairs done at a Apple Authorised Outlet. After installing everything again I just found out that my iBook will not sleep when the lid is closed. The screen is still on and bright. Any ideas why? Is this dangerous? Any quick fixes?
Cheers,
Jack

Jack,
Welcome to Apple Discussions.
You need to give the Apple Authorized Repair center a call back and let them know what's going on. I've seen this before here on the forums, and it was attributed to a sleep magnet not being put back in. It's most likely this. Apparently, putting this magnet back in can be easily overlooked.

IBook Will Not Automatically Sleep

Lately I have had a problem with my iBook G4 not automatically going to sleep after the specified period of time. Obviously this is a problem when running on battery power! I usually have it set to sleep after 15 minutes of inactivity to save the battery, but it will not go to sleep. I'll come back a few hours later to a dead battery. It does sleep when I shut the lid, and it goes to sleep fine when I select Sleep from the  menu. It will also go to sleep when the battery is low (about 2%). It just will not sleep after the interval that I set.
I have tried the following:
Deleted the powermanagement.plist file then rebooted.
Verified the HD and repaired disk permissions both from disk utility and install disk.
Tried the cmd-shift-option-power reset option after shutting down, still the same...the iBook will not go to sleep on its own.
No software is running, no additional RAM has been installed, and this happens on both battery and AC power. Any thoughts?
iBook G4, 12" 1.33 GHz Mac OS X (10.4.9)

Restart and hold down on the "shift" key until you see the spinning gear icon. This will startup the iBook in "safe" mode. Test to see if the iBook sleeps normally now. If it does, then you have some kind of third-party software conflict. If it doesn't, then you might consider resetting the Power Management Unit:

"cmd-shift-option-power" is not the same thing as "control-shift-option-power"...

Anybody else have this problem?

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)

Try a Reset [Hold the Home and Sleep/Wake buttons down together for 10 seconds or so (until the Apple logo appears) and then release. The screen will go blank and then power ON again in the normal way.] It is app and data safe.

HP Envy Will Not Sleep Automatically

My computer will sleep fine if I tell it to, but it won't do it automatically. That function is critical to my computer's security.
I confirm that I've told it to sleep after 1 minute, whether on battery or plugged in. If I tell it to dim the screen after a minute, that works fine, but it will not sleep.
Below is the Power Efficiency Diagnostics Report (Forum removed HTML) -- note the errors.
I have unplugged all USB devices. I have stopped the WIndows Media Network Sharing Service. I have disconnected from the network (airplane mode). It still will not sleep.
Please tell me what else to try.
Thanks.

Macbook Pro 13" will not sleep when I shut the lid

Hello Community,
This is my first time using the forum. I have a macbook pro 13" 2009 model. Recently I had my MBP connected to an external monitor. I shut the lid while it was connected to the monitor and forgot to turn off my bluetooth mouse. Later that night the mouse was bumped, waking my macbook and setting it to clamshell mode. I put it to sleep again, opened the lid and woke it, but the LCD on the laptop did not turn on. I reset the PRAM and the NVRAM with no luck. I disconnected the monitor, rested the P/NVRAM and it would boot with the laptop screen and once everything was loaded my screen went black and then went to sleep on its own. I tried powering on and off using the P/NVRAM key commands...and nothing. So I opened the bottom case and physically disconnect the battery, reconnected the battery, put the bottom plate back on and powered it up. The screen began working again, now I have a new problem, the MBP WILL NOT sleep when I shut the lid anymore. I even reinstalled the OS and still no luck? If anyone has anything helpful that I could try to get this feature working again it would be much appreciated. If there is some terminal command I could try or some other troubleshooting method. I even put a magnet by the right side of the keyboard to try to trigger the sleep switch.
Any advice would be appreciated.

I resolved my issue in a very unlikely way. In my earlier post I mentioned that I wiped my hard drive and was starting from scratch. Well I reinstalled windows 7 through bootcamp and it fixed my sleep issue. That's right folks...Windows fixed my mac. I think that it was an EFI issue. I think this because windows 7 uses EFI and during installation it must have reset the sleep values to normal. I feel when you reinstall Mac OSX the EFI partition on the drive should get wiped and reinstalled as well. I also feel that apple should have an option within System Prefs for the user to select what the way is that the computer responds when the lid is shut instead of the ritual of trickery and problems that the clamshell mode can cause.
Hope this helps someone.

Ibook will not boot PLEASE HELP!!!!

Hi,
First the ibook booted then would come up with the kernel error: square box with "you need to restart your computer. Hold down the power button for several seconds or press the restart button......
I then booted to single user mode and ran fsck -y which eventually came up with the all clear "The volume Macintosh HD appears to be OK"
I then restarted the system which booted to the blue screen with some quirky graphics towards the top. It will now not boot into single user mode, just black screen or multi-coloured stripy screen. When booting from the CD drive the sceen is just blue or black.
Okay, I have connected the ibook via fire wire to a powerbook, and re-booted the ibook in terminal mode which brings up the fire wire connect symbol on screen.
After a while the system stalls showing part of the symbol and the connection is frozen. I have tried to re-install tiger using the powerbook to initiate as the ibook will not. However, it freezes at 50% of install.
I changed the ram to iliminate a ram failure, however... still the same.
While I was in terminal mode I erased the disk using the disk utility from the PB and then ran the install again... still froze.
This looks more serious than I thought. I'm now thinking that it could be the hard drive or worse. I have tried to use the apple support phone # and it does not seem to work, 1800 275 2273.
I'm having some real bad luck here. Any ideas?

I ran the apple hard ware test disc. The quick test found no errors. The extended test freezes up completely. Now I'm really stumed. The logic board came up with know errors.
When the system froze on the extended test. I falsed a re-boot. However the screen went black so I could not run the test again. It seems like a time thing... the ibook can only run for a short period before it freezes. Then it has to shut down for a while before it can run again

After installing recent java + security update, computer will not sleep

After installing the recent java, daylight savings, and the security update. my computer will not sleep. Does anyone else have this problem? I do have an adaptec usb2 card installed but nothing is plugged into it. Also i don't have any Ipods or external things plugged in. I have had the same setup for the past year with no problems, now it will not sleep. I have also tried repairing the permissions. Please help

When you select Sleep from the Apple Menu nothing happens, is that correct? Try this: Go menu > Home > Library > Preferences. Drag the whole of the Preferences folder to the desktop. Restart your mac, don’t worry if things look different, you have not lost anything. Can the mac sleep now? If yes, then its a damaged or corrupted .plist or preference. If you are using Apple Mail, drag the com.apple.mail.plist back to the new preferences folder created on reboot, you dont really need anything else but keep hold of the old preferences (the one you dragged to your desktop) just in case for a month or two. If everything else is OK you can safely delete it. If it has not cured the problem then remove the new preferences folder created on reboot by taking it to the trash, drag back the preferences folder you moved to the desktop and reboot. Now reinstall a clean OS. See how you go from there

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.
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 10.4.8 Combo update. Others reading, download the combo update that applies to you!
Cheers!

IBooks will not sync PDF collections with my IPhone. It syncs the collection title but not the content?

My IBooks will not sync PDF content with my IPhone. It syncs the collection title but no content. Both devices are set to sync collections? Any ideas how to fix this?

The 'sync collections' setting does not copy books or PDFs between devices - all it does is if you have the book on both devices and you move it into a collection on one of them, then it will be put into the same collection on the other device.
You will need to sync each PDF that you want on your phone. If you don't currently have them on your computer then connect your iPad to your computer's iTunes and do File > Devices > Transfer Purchases to copy them over (that should copy PDFs and/or epubs that are in the iBooks app, not just actual ibooks), and if using a Mac with Mavericks on it do File > Move Books From iTunes in the iBooks app on it, and you can then sync them to your iPhone.

Will Not Sleep In Energy Saver Mode

My iMac G5 20" 1.8Ghz will not sleep when I set it to sleep in the energy saver panel. This just started for no specific reason a few months ago. It will sleep fine when selected from the Apple menu. I have been through the discussions and no one seems to have a good fix for this. I have repaired permissions, reset the PRAM and SMU, and tried all the different configurations in energy saver. I called AppleCare and they seemed not to know anything about this issue. They recommened an archive and reinstall of the operating system. I feel this is kind of drastic for this and I have not yet tried it unless I can see that other people have done it and it works. My computer is in the repair program for the power supply problem and it has an updated power supply since the original actually smoked and Apple replaced it. I was wondering if anyone out there has had this same sleep issue and got it resolved?

Well I finally decided to try and delete an application that I suspected could be a problem not allowing my computer to sleep automatically. That application is LAST FM a music service from the UK which is actually quite good. I suspected it was a problem since it would always launch when I opened iTunes and asked if I wanted to share my iTunes library with the LAST FM group which I did not. I selected I did not want to share in the LAST FM preferences but it still opened anyway when I launched iTunes. I deleted the program and repaired disk permissions and *It Worked*, my computer will now go to sleep with the settings I selected in energy saver. I know there are other people out there with this problem I would first look at this application and others that are probably running in the backround causing your computer not to sleep automatically. I am a firm believer in trying to work up from the easiest solution before taking the drastic approach, such as a system reinstall, or a logic board replacement. I did take Nikki's suggestion seriously. My power supply had been replaced in the repair program and my logic board did not meet the criteria for replacement since it was not exibiting the symptoms that required its replacement such as video and power problems.
