PowerBook G4 not going to sleep when closed???

My 15-inch 1.67 GHz PowerBook doesn't go to sleep when closed. The Apple on the back on the display stays lit and the display doesn't go dark either. Anyone have any ideas???

Check that your sleep magnet hasn't fallen. Take something made of steel like a paperclip, and see if it sticks to the outside of the case above the Apple logo. If not, the magnet inside may have moved. When the cover is closed, the magnet is directly over and affects the trackpad area. If you have a magnet (like on your refrigerator), wave it over the trackpad and it should go to sleep.

  • Computer not going to sleep when lid closed

    My wife's new MacBook Air has a couple of problems we can't figure out.  First sometimes the computer is not going to sleep when lid is closed and when we lift the lid everything is frozen.
    Second, the user Library folder is not seeable in her user account.  I know it's there because on the side bar there's a short cut to Preferences folder which we can open.
    Strange behavior.
    Thanks,
    Ron

    Ron,
    The user library folder (~/Library/) is hidden by default in Lion. I assume Apple doesn't want people mucking around with the sensitive files in there. So this is normal behavior.
    As for the freezing issue, I would suggest you reset your power management and perform a safe boot to clear out caches. You should also see if the issue persists after disconnecting USB perhipherals.
    Here's how:
    Power Management:
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer. 
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
    Safe Boot:
    Be sure your Mac is shut down.
    Press the power button.
    Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).

  • MacBook not going to sleep when connected to WiFi

    Hi there,
    my MacBook 3,1 is not going to sleep as long as it is connected to WiFi.
    It starts the process of going to sleep as my VNC connection gets dropped but it stays awake. I can easily reconnect.
    Everthing else is working fine. Any suggestions?

    Hello everyone,
    I'm facing the same syptom. I tried many things and now havw to live with putting the MacBook to slee by hand. I had some other issues just before that:
    1: The MB returned randomly from sleep while being closed. That was annoying. I think it was fixed after installing smart sleep and doing some cleanup in the preference files.
    2: Then I was put "randomly" to sleep. I figured that came from overheating the processor (thus I'm gld it went to sleep). The fan speed control was set to constantly 2000 rpm. Installing fanControl helped.
    3: Lid closing did not init the sleep mode and the backlight is not turning off. Niether does it wake up on opening when I put it io sleep manually (I have to press a key).
    The sensor for closing the lid seems to work, if it is the same which controls the maximum brightnes of the sleep indicator light (pulsing). It is darker when the lid is closed.
    I wonder if there is some settings tool.
    Besides I think the issues started after the Software updates around 12th of dec. 2008, with MacOS10.5.6 and the EFI & SMC firmware updates.
    I'm eager to get answers.
    Kid regards, Ralf.

  • Thunderbolt drive not going to sleep when iMac does

    Not sure if my title makes sense...
    Ok, I have an Intel iMac running the latest version of the O/S
    Attached via firewall I have a Lacie external 2big drive
    Attached via thunderbolt I have a lacie 2big thunderbolt drive
    When the iMac goes to sleep by itself, i.e. I walk away and let the system decide when to sleep, only the firewall connected drive shuts down.
    The thunderbolt drive remains live with that nice big blue lamp on the front of the drive remaining lit.
    If I manually put the imac to sleep, then both drives shut down. I'd really like both drives to shutdown properly when the system decides I've gone to bed....or gone out or whatever.
    Any suggestions?

    I have exactly the same problem with three lacie_2big drives.  Thay do not go to sleep when my iMac is sleeping.  I never had this problem untell using OS X Mavericks.  Please help!

  • Monitor not going to sleep when close my lid to MacBook Pro

    Hi. I was wondering if there was anyway that I could get my Dell E173FP monitor to sleep when I close the lid to my macbook pro. I do not have it on mirroring mode. When I close the lid to my laptop it will just switch my desktop to the monitor instead of the monitor going to sleep with my macbook. When I press the power button and click sleep or go to the apple menu and click sleep it will work though. This really irritates me and I would like It to sleep when I close the lid instead of having to do more. Please help.

    Sounds like the system is going into Clamshell mode.  Here's some info on that mode. 
    One workaround would be to disconnect line voltage as that's required for clamshell mode, there may be others.

  • Not going to sleep when PC is connected via SMB

    If I have my mac set to go to sleep after a period of inactivity, it goes to sleep while my PC is still connected to it via SMB. Not while any files are beig used, but if they're not used for a while. Is there any way I can change this anyone?

    Sorry - I was very tired when I posted that - I guess it could have made more sense!!
    What I want is for my mac to only go to sleep if there's nobody connected via SMB.
    At the moment, I either have to set the sleep timer to never, or when I start to work on a file from the mac on the PC I find that the Mac's gone to sleep even though the PC's switched on and connected to it. Then I have to go and wake up the mac and reconnect with the PC.

  • Macbook pro does not go to sleep when closing lid

    Hi,
    I'm having a weird problem with my macbook pro. When I close the lid, my macbook does not go to sleep. Even more weird: when I put my macbook to sleep using cmd + alt + the eject button or using the apple button => sleep, my macbook stops sleeping as soon as I close the lid
    It seems like this problem occured after installing the Nosleep extension for mac (http://code.google.com/p/macosx-nosleep-extension/). I already deleted that program and rebooted, but that did not help.

    Please read this whole message before doing anything.
    I've tested these instructions only with the Safari web browser. If you use another browser, they may not work as described.
    This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac. 
    These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing. 
    Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects. 
    Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands. 
    Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply. 
    Launch the Terminal application in any of the following ways: 
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.) 
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens. 
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid. 
    When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign. 
    Step 1 
    Triple-click anywhere in the line of text below on this page to select it:
    kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -ef 
    Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
    Step 2 
    Repeat with this line:
    { sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; echo; sudo defaults read com.apple.loginwindow LoginHook; echo; sudo crontab -l; } 2> /dev/null | open -ef 
    This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. 
    Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step. 
    Step 3
    { launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; echo; crontab -l 2> /dev/null; } | open -ef 
    Step 4
    ls -A /e*/{cr,la,mach}* {,/}Lib*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -ef  
    Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting. 
    Step 5
    osascript -e 'tell application "System Events" to get name of login items' | open -ef 
    Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output. 
    You can then quit Terminal.

  • PowerBook G4 not going to sleep

    My PowerBook G4 (1,5 GHz; 12") failed to go to sleep (it did, but only for some seconds). The Bluetooth was also "not available". I cured the issue in this way: I reset the PMU and checked the hard disc using the Disc-repair on the installation-DVD (OS X Leopard). The hard disc did not need any repair, bur the programme did some repair in the authorities. After this I rebooted the PowerBook and now the Bluetooth is back and the PowerBook stays asleep wen put to sleep! Hopefully somebody is helped by this.

    Welcome to the Apple discussions.
    Thanks for posting. A PMU reset will often repair things that are power-related. Here's Apple's note on what it covers: http://support.apple.com/kb/HT1431

  • Not going to sleep when I close the lid

    Hi there,
    My MacBook Pro is just about 6 months old, I just got it back from an Apple Servicecentre. They exchanged my keybord and total unibody because my enterkey didn't work properly, it was entirely done under guarantee.
    But now, when I close my lid, it doesn't go into sleepmode... I used to have no problem with that. Do I have to change something in the settings?
    Thanks for the help,

  • Macbook Pro 8.2 does not sleep when closing the led.

    I have a macbook pro 8.2. When I close the led, it sleeps then wakes up immediately. I can't put it to sleep by closing the led becaus it will wakes up again. So, If I want to put it to sleep, I have to choose the sleep option from apple menu. I am affraid that it is a hardware problem, something wrong in the sensors.

    Since this is a 8.2 MBP it is fairly new, I have an 8.2, it has still got a lot of the original 1 year warranty left on it.
    Just how do you know it is not going to sleep when you close the lid? Does the monitor not turn off? Does the sleep light on the front not come one and then slowly go out and come on again (flash slowly) when you close the lid?
    If the screen doesn't turn off or the sleep light doesn't come on and then flash slowly you need to take it in to get it fixed ASAP.
    If those things are happening, the screen turns off and the sleep light comes on then goes out then back on slowly, the MBP is actually in sleep mode. Even if once you open the lid it comes right back to life wvwn if it doesn't ask for your password. This is a setting in system preferences.

  • Computer hanging on closing lid and not going to sleep, indicator does not blink

    i have a 1 month old Macbook Pro 13" i5 with 4Gb memory.
    when i am closing the lid the computer is not going to sleep, hard drive continues to spin and power indicator does not blink and it remains solid.
    on opening the lid again screen keep blank and does not show anything while i can hear spinning of hard drive. than i have to forcefully shut off the computer by pressing power key and than computer starts after that.
    Apple support told me to press shift+control+option+power and than start computer, it fixed the problem only once and they told me to do it again when it comes again. but write now i am getting it everytime.

    Hi guys -
    First off make sure you don't have 'Wake for ethernet access...' enabled in System Preferences/Energy Saver/Options - I'd also run Disc Utility and repair your permissions as well. OS X requires 'maintenance routines' to be performed on a certain basis and you can use this free application to help you with that...Onyx.
    Check the obvious as well - that you don't have any applications that might keep your Macbook awake ...some printer utilities do this for example.
    After all this shut down and restart and hopefully things will be better - if not, there may be a chance that the mechanical parts that put your computer to sleep may be at fault ...and you'll need to visit an Apple dealer to verify this.
    Hope some of this helps.

  • T540p will not go to sleep when the lid is closed

    I recently got a T540p and all settings in Windows 8.1 are set to "sleep" when either the power button or lid is closed. Neither of these work, the screen stays on when the lid is closed. If I let the computer idle long enough, the computer will enter sleep. I've used Lenovo System Update to get the latest drivers and there is nothing outstanding. Could someone please advise if there is anything else to check?

    Hi Adamstirtan,
    Welcome to Lenovo Community!
    As per the query we understood that you are facing issue with system not going to sleep mode on your ThinkPad T500.
    Go to Control Panel\All Control Panel Items\Power Options\Choose what closing the lid dose – When close the lid – On battery sleep – Plugged in sleep.
    To prevent programs from waking your computer:
    Open Power Options by clicking the Start button Picture of the Start button, clicking Control Panel, clicking System and Security, and then clicking Power Options.
    On the Select a power plan page, click Change plan settings for the plan that you want to change.
    On the Change settings for the plan page, click Change advanced power settings.
    On the Advanced settings tab, expand Sleep, expand Allow wake timers, choose Disable for both when your computer is running on battery and when it's plugged in, and then click OK.
    Hope this helps.
