Hi there

My laptop has suddenly stopped booting up and gets stuck on a blue screen, identical to descriptions by a couple of other posters on here.

From some of the replies, can someone tell me what 'safe booting' is, and how I do it?

Many thanks

    What is Safe Boot, Safe Mode? (Mac OS X)

    Try this:
    • Shut down the computer.
    • Locate the following keys: Command, Option, P, and R. You will need to hold these keys down simultaneously later.
    • Turn on the computer.
    • Press and hold the Command + Option + P + R keys immediately after the startup chime.
    • Hold keys down until you hear the startup chime for the third time.
    • Release the keys and immediately hold down Shift key to start up in Safe Mode.
    • Log in and empty Trash.
    • Restart normally and log in.

    Please do post back and let me know how it goes.

    Cheers

    Thanks for your reply.

    I have tried that method twice, to no avail.

    Can you confirm that the option key is the key with alt on it? (If it isn't, then that could explain why it didn't work!)

    I have managed to do a target disk and can access all my files - I guess the thing to do is get all my stuff off and do an erase and install, unless you have any other suggestions.

    But thank you for answering.

    Hi Becka!

    "Can you confirm that the option key is the key with alt on it?"
    Yes that is the Option key.

    "I have managed to do a target disk and can access all my files - I guess the thing to do is get all my stuff off and do an erase and install,..."
    Yes you should create a backup, but it may not be necessary to perform an Erase & Install yet.

    Exactly which model 12" PowerBook G4 is it?
    What is the Processor speed?
    What size is the Hard Drive, and how much space is available?
    How much RAM is installed, and is it original or added?
    Which version of OS X is installed?

    What happened between the last time the PowerBook started successfully, and when it didn't?
    Have you made any changes, like upgrading the system, updated or installed any applications or programs, etc?
    Have you disabled, deleted, or added any Fonts?

    Have there been any unusual occurences, like freezes, crashes, power outages, etc?

    Run Repair Disk, and post the results.
    If errors are found, that Disk Utility cannot repair, instead of an E & I, you could also choose to use a more robust Third-Party utility, like DiskWarrior, TechTool Pro, or Drive Genius, to save the drive.

    THESE ARE THE STEPS FOR USING DISK UTILITY TO REPAIR YOUR HD
    1.Insert the System Install disk, Mac OS X CD-ROM disk, or Restore DVD disk, then restart the computer while holding the C key. Use the System disk, of the OS, that is currently installed.
    2.Once started up from CD or DVD, on the Menubar at the top of the screen, choose Disk Utility from the Installer contextual menu for Panther, or Utilities for Tiger.
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from disc to access Disk Utility.
    3.Click the First Aid tab.
    4.Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
    5.Select your Mac OS X volume, if necessary.
    6.Click Repair. If DU reports errors it has fixed, re-run Repair Disk until no errors are reported.
    7.Repeat steps 5 & 6, but select the Hard Drive this time. It's usually the first listed with the manufacturer's model number. Make note of the S.M.A.R.T. status.
    8.When finished, select Quit Disk Utility from the Installer menu.
    9.Select Quit Installer from the Installer menu.
    10.In the resulting pop-up window, choose restart.
    11.After the computer has restarted, you can eject the CD.

    Exactly which model 12" PowerBook G4 is it?
    PowerPC G4

    What is the Processor speed?
    1.5GHz

    What size is the Hard Drive, and how much space is available?

    55.8 GB Size
    18 GB Available (ish)
    How much RAM is installed, and is it original or added?
    512mb - original.

    Which version of OS X is installed?

    Came with Tiger, installed Leopard upon release, now on 5.2

    What happened between the last time the PowerBook started successfully, and when it didn't?

    I had put quite a bit of images /music files on the desktop as i was doing a show. My intention was to transfer it all to an external HD and then remove it from the PB. I was using Comic Life and had a few progs running (can't remember what) and I shut my laptop lid, without quitting progs etc. When I went back to the PB, it wouldn't go to password and the screen remained black with spinny ball. Eventually I held the power button down and then attempted to reboot. It hasn't since then.

    Have you made any changes, like upgrading the system, updated or installed any applications or programs, etc?

    I may have done an apple software upgrade if there were any, but no major ones. (I think 5.2 had been on it for a while)

    Have you disabled, deleted, or added any Fonts?

    No.

    There had been no unusual activity. I think I had the available space down to about 12GB, but was erasing files as I'd finished with them...

    Hope that gives a better picture and thanks for clarifying the option key thingy for me!

    You're Welcome Becka!

    Have you run Repair Disk yet?
    If not, when you do, post what is displayed for Capacity, Available, and Used.

    Capacity: 55.77GB
    Available: 20.13GB

    Becka,

    What was the result, of the Repair Disk procedure?
    Was the drive repaired, or were there any error messages?

    ali b
  • Becka Mac Level 1 Level 1 (110 points)
    This was done via target disk mode.

    It verified the drive and told me that it seemed to be ok.

    I clicked on repair disk and it told me it was unable to mount disk.

    Not completely helpful, so any suggestions....

    I am having the same problem.
  • ali brown Level 7 Level 7 (26,465 points)
    Becka,

    Run Repair Disk, directly on the PowerBook, not TDM, using the procedure I Previously Posted.

    HI, I have been having all sorts of freaky problems since I updated...what a waste!! I also have th blue screen dance on startup, and i was going to do another clean install but now i cannot even use my boot CD!!! nor start up in Safe Mode, OR SINGLE USER mode...this is very sad, I rely on my computer for everything because Im far from everyone I know, and now i cannot access my computer at all...however there is hope, because others are having the same problem, i dont know how to fix it since I cant even log on, i mean i cant use the 10.5 cd to log on or anything, and it seems to have done something to my CD drive...like it doesnt work, wont boot up...?? Has anyone solved this issue? If oyu are having this issue id suggest you do a clean reinstall of 10.5 and NOT update to 10.5.2, cause that's when i started having all these problems...Is it possible Macintosh is running DOD or DOJ spy bugs in their software?
  • TTeuer Level 1 Level 1 (40 points)
    It should not matter whether or not it's run directly off the CD, in TDM, or even in the operating system if you're running Tiger and above just to verify and see if their are issues.
  • Rangddrol Level 1 Level 1 (0 points)
    HI, I think that Cornelius described resetting the PR ram, and not a safe boot...a safe boot is when you hold down, i think, im pretty sure, the shift key after rebooting...

    IF you get any answers please let me know, i still cannot access my computer, since i cant get beyond the blue screen. I think that there is some bug in the system and it doesnt seem that Apple wants to acknowledge this, otherwise, we would have gotten an answer.

    If you can reboot, with your original install CD. I would suggest you erase and reinstall, hopefully you have been using Time Machine and made backups...Ive backed up using Time Machine and its never taken care of the problems...at this point if i ever get back to my computer, I want to just go to 10.5 and wait for further fixes...I might even just like to go back to 10.4.11!! Best of luck, and again, please let me know if you resolve this. Rangdrol (konchokrangdrol@gmail.com)
  • cornelius Level 6 Level 6 (17,825 points)
    Rangddrol:

    Actually the procedure I outlined is a combination of Resetting PRAM and Safe Boot. You go directly from PRAM reset into Safe Boot.

    Cheers
