Starting up and shuts down after 30 seconds

My powerbook started doing this. It's starting up, you hear the chime , then the spinning thing with the gray screen, then it shuts down after about 30 seconds.
I did try a few things that I've read in different threads. I can do the single user mode and the black screen comes I can type the things from this thread but it doesn't look it works.. https://discussions.apple.com/thread/1801027?threadID=1801027 . I did type those commands w/wo the "+" signs.
Please help

The plus signs were remnant discussion formatting keys and are not part of the commands.
OK, here goes on what to do.  Boot into single user mode.  Then try the following  command
/sbin/mount   -uw   / <enter>
which mounts the boot volume as write-enabled (it normally comes up read-only to begin with) then this command:
/sbin/fsck   -fy   / <enter>
And let it attempt the repair of the boot volume.  It will either report that the volume is OK or that it has been repaired.  If it has been repaired, then repeat the second command until it just says things are OK.  Please post the results.
Note that usually, in single-user mode, those commands will appear as an advisory just before the first terminal prompt.

  • G4 MDD FW800 starts up and shuts down after several seconds

    Hi all,
    My G4 MDD FW800 DP.1,48 starts up and shuts down after about 20 seconds. I Have reset PMU and checked battery voltage, witch was OK. (also had it out for 30 minutes with no power connected etc.) I have video and also tried with NOTHING connected. But still it just powers down and failes to enter start up procedure.
    Last time I had it running I pulled my iPod, beacause the computer did't see it, the next thing I saw on screen was the message to hold the power button for 5 to restart, after that I got the problem described above.
    Anybody?
    Thanks,

  • Slow start up and shut down after Zenworks installation

    I hope someone can help me out on this one. Not sure if I am posting the
    right forum or not but here we go. After I installed Zenworks on our PC's
    here at work, we have a noticed a distinct difference in how long it takes
    for the PC's to start up and shut down. Before installation, everything
    was very quick, like it should be. Now it seems to take some users 3-5
    minutes to start and shut down their PC's. The machines are running
    several different OS'es. Windows 98SE, Windows XP Pro SP1 and Windows XP
    SP2. No one OS has more problems than the other. Has anyone heard of
    Zenworks causing this issue or heard of a way to prevent this? I would
    really appreciate any help you can provide.
    Thanks!

  • SL takes longer time to start up and shut down after "IceClean".

    Greetings,
    After "IceClean" (both maintenance and cleanup), SL seems (obviously) to take longer time to start up and shut down.
    Any idea why and how can I resolve it?
    Thank you so much.
    Cheers.

    Hi,
    I've finally able to solve the problem. The problem was due to start up item. There were 2 trial application (expired long ago) in the folder. After clearing the application, start up and shut down are fast as light.
    I think I've "awaken" the start up application after "IceClean" as IceClean has deleted their log file or something like that and therefore the applications have to run again.
    In order to be fair to IceClean, it is my fault to be blamed.
    Thanks again.
    Cheers

    my computer displays grey screen and apple logo for 10 minutes or more during start up and shut down. sometimes it refuses to shut down . this issues started after installing OS lion. what do i do?

    I don't think it's exactly an incomplete installation brody, but most likely in-correct permissions somewhere along the line that either happened, or became magnified during the upgrade. Also, it could be corruption as well.
    First thing to do, is boot up holding down Shift key to do a safe-boot so we an clean up any corrupted OS caches, after that do another reboot, but go to the Lion recovery, and scan the HD for errors, repair any if you find them, and then try to do a Repair Permissions job.
    That should fix the issue, if not, we can start doing a PRAM reset  and SMC for good measure.

  • Start up and shut down is slow after erasing free space using disk utility?

    I went to Disk Utility, clicked Erase, and then "Erase Free Space." When I saw that it was going to take 1 hour and 30 minutes, I tried closing disk utility. It wouldn't let me exit, so instead I pressed "Skip." But when you hover over the "Skip" button it says, "Erase all data and reformat the disk."
    I'm wondering if the fact that I pressed the skip button has anything to do with my computer shutting down/starting up A LOT slower now. If so, what can I do to fix it?
    Thanks!

    Just wanted to give an update. I called Apple and apparently, you shouldn't empty the free space using disk utility while you're logged in. I had to insert the Installations CD and press the "C" button while my computer restarted, and used Disk Utility from there. My start up and shut down speed still isn't exactly the way it was before, but this definitely made a difference.
    Thank you to those who replied to my question!

  • Slow to start up and shut down

    Hi.
    I have updated MacBook Pro from 2.16 GHz with OS 10.4.11.
    The old one started up and shut down very fast. Now my new 2.4 GHz one starts up very slow.
    I see the gray screen forever till finally see my desktop. It happens even I installed the OS on a cleaned HD.
    Cleared all the cache, there is no log in items.
    Reseted the PRAM.
    No problem with Disk permissions.
    Both 1GB memories are recognized.
    I did everything I could think of.
    Does anyone have any idea what is wrong ?
    I would be much appreciated if any one know !
    Thank you.

    22 sec startup
    Definitely an improvement over our old IBM AS/400 mainframe that once took six (6) hours to start up after a bad shutdown....

  • I tried many times to turn it on, it turns and the same white screen appears and the update starts again and shuts down. Please Help me!

    Hello!
    I have a MacBook Air. I have got a software update notification couple of days ago. I've clicked on it today, and it started installing updates.
    But, I have got a notification telling that not all updates were installed successfully, then I have clicked on "Restart" from the notification box. Then my Mac restarted and the white screen with Apple logo and the update progress appeared (like what always happens during updates).
    The problem that while the update progress reached around half the way, my Mac shutdown. I tried many times to turn it on, it turns and the same white screen appears and the update starts again and shuts down.
    Please Help me!
    MacBook Air (11-inch Mid 2009)

    Welcome to Apple Discussions
    You did not state whether you installed the update while on battery (not mains) power. You are warned not to apply certain updates without being connected to a charger & mains power.
    Also remove any attached peripherals.
    Reboot in Repair mode (command-R at start)  and use Disk Tools-Disk Utility-Disk First AId to repair your disk, and as long as you're there repair permissions. Next quit Disk Tools and reinstall the OS. After completing that successfully reboot, log in and do a combo update.
    You must have more than enough (not just enough) empty (free) disk space for the update.

  • Hi. There is a ghost search bar on my iMac screen which flashes constantly, even during start up and shut down. How can i make this go away? Please help. x

    Hi There is a ghost search bar on my iMac that flashes continually, even during start up and shut down. How can i make this go away? Please help. x

    Please read this whole message before doing anything.
    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
    Step 1
    The purpose of this step is to determine whether the problem is localized to your user account.
    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
    While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Please take this step regardless of the results of Step 1.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

  • How do I decrease the start up and shut down time?

    Processing pin wheel becoming more prevelant an time for start up and shut down is increasing.

    Start by using this utility that is already on your Mac:
    Using Activity Monitor to read System Memory and determine how much RAM is being used
    What Mac OS X are you using?
    How much Green in the pie chart? How much Blue?
    How many pageOuts since last startup?

  • Slow start up and shut down

    I know this might be normal for every Mac or PC,
    my PB is 6 months old, and it's start up and shut down time is kind of slower than before, can anyone kindly tell me the reason about this please??
    Thanks^^

    Try using Disk Utility to repair your startup disk (hard drive) as shown in Dr.Smokes repair thread.
    Doing the things in his link is a good start for a monthly maintenance program.
    Do everything in the link and let us know.

  • Start up and shut down services

    Hi team,
    Could tell me how to enable the start up and shut down services in unix environment?
    Regards,
    Rajesh

    What services to you mean ? You mean how to run a program ?
    Unix systems don't really have services like Windows. If you want something to start automatically when you reboot the server then usually you place a script under /etc/init.d or a similar location (it depends on what unix you are running)
