  • Macbook won't fully start up

    Yesterday afternoon, I powered down my Macbook to go to class. When I got to class, I pushed the power button, heard the loud trumpet noise, went through the white startup screen, the blue screen and then my desktop background came up. But then, nothing! My dock won't come up, the menu bar at the top won't come up. I've tried restarting, but to no avail.
    I recently installed Leopard - could that be the reason? Should I just attempt to restart from the disk?
    Thanks!

    You were likely running at least Snow Leopard, if you were using Time Machine to back up. I can't imagine that you would have done any damage to your internal drive just by backing up - your internal drive may have been failing all along, causing the backup to fail as well.
    Try a couple of things - first try starting up whilst holding down the option key - see if you've any drive available that can boot your machine, even if you were running Lion you should have a Recovery partition. If that doesn't work, and you were, indeed running Snow Leopard, find the SL installation disc or the disc that came with your machine and boot from one of them. Try running disk Utility to see if your internal drive can be found, verified and repaired.
    None of this may work - but it's worth a shot.

  • HT3964 macbook pro will not start on battery power works fine when plugged in

    My macbook pro 15 inch early 2008 model will not start on battery power but works fine when plugged in.

    check the battery info.. >about this mac>more info>system report and select "power" on the lefthand column.  How many cycles? What does it say about the condition? etc.

  • MacBook won't complete start-up after today's software update

    The laptop was working fine, and while I was reading mail, using internet, etc. I got a message from Software Update that there was a Security Update for Intel based computers. First I did the iPhone update that also came today, then the security update and restarted. The computer hangs as soon as the Apple and the spinner appear. I did the fsck thing and it found nothing wrong. I started up from the system disk and ran Disk Utility and it found nothing wrong. I started up from the disk again with "d" and ran hardware test and it found nothing wrong. I did the Applecare disk too. Everything checks out fine -- but as soon as I boot from the hard drive, it hangs. What do I do now?

    Something like this happened to my MacBook after installing iTunes 8 and the QuickTime update. I ended up having to rewind it with Time Machine. I wish I had a better answer.

  • Macbook won't complétela start what do I do?

    my MacBook won't completely start up. it comes on but the screen is white with a grey folder with a question mark in the middle of it, what do I do?

    Read the instructions (10.4 / 10.5 / 10.6) here >  A flashing question mark appears when you start your Mac
    When you post for help the more details you provide, the easier to assist you. Please tell us which Mac OS X you have installed. Thanks!

  • Macbook won't start

    Macbook won't start up.  Sounds like disc drive is spinning but screen remains dark as though startup file is not booting.

    Did you also try reset of NVRAM/PRAM?
    http://support.apple.com/kb/HT1379
    When you tried the Command + Opt + P + R keys on restart, held almost
    immediately and through the time period it should chime on startup, did
    you keep holding those keys down, so as to force it to repeat the chime?
    You should do this (if possible to tell) through Three chimes, before you
    let those keys go; that would be indicative of a NVRAM/PRAM reset.
    Aside from the details and troubleshooting processes in the SMC reset
    article from Apple Support, that could shed some light on the issue, if
    these were done in their subscribed order before finally trying the SMC.
    Have you tried System Management Controller (SMC) reset more than once?
    http://support.apple.com/kb/HT3964  {and those other troubleshooting bits}
    Depending on which MacBook you have, the details may vary; with some
    you could try several items not possible with a later model, such as a hard
    reset of the computer (remove battery, hold power button, etc) and other
    details I am not going into now... Here's something that worked for this one:
    •My MacBook won't boot, no start chime, just DVD spinning sound:
    http://www.ifixit.com/Answers/View/6271/My+MacBook+won%27t+boot,+no+start+chime, +just+the+DVD+spinning+sound.
    There are some ideas there which may help. At least as far as trouble-
    shooting. If you have access to an Apple Store with Genius Bar in the
    USA or Canada, you could call ahead for an appointment to have one
    of their staff genius tech persons diagnose and troubleshoot this issue.
    In other locations, there may be fees charged to accommodate services.
    Anyway, I an not certain what to suggest next.
    Did you try booting from the Snow Leopard DVD?
    Good luck & happy computing!

  • Macbook won't get past the grey start up screen

    I purchased my Macbook in 2008, roughly July.
    My fiance unknowingly shut down my macbook in the middle of start up. Before that it was running perfectly fine, I had no issues.
    After my fiance stopped the start up, the macbook won't turn on. It'll load up to the grey loading screen (example here)... It doesn't make much noise as it starts up either. I have all original discs that came with the macbook, if that helps any.
    I'm frustrated, as I can't afford to replace my mac at this point.
    Any idea what I can do?
    Thanks..

    Hopefully, nothing permanent. Do the following:
    If you have Snow Leopard installed:
    Reinstall Snow Leopard without erasing the drive
    Do the following:
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.
    If you have Lion installed:
    Reinstalling Lion Without Erasing the Drive
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion and click on the Continue button.
    Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.
    If you have Leopard installed:
    How to Perform an Archive and Install
    An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
    1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
    Repairing the Hard Drive and Permissions
    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
    3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
    4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
    5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
    6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

  • Macbook won't start - apple icon turns to circle with diagonal line/slash

    My Macbook won't start. When I turn on the power, the apple icon appears but then after a while it changes to a circle with a diagonal line/slash, then it just shows a gray screen.
    The last time I used the computer I did several software updates. Could this be causing the problem? Any suggestions for getting my computer operating again?
    Thanks for any help/advice.

    Yup, i encountered the same experience after a strange failed USB-loading, and a sudden shutdown of my macbook.
    Luckily i manage to "safe-boot" (pressing "Shift" key once starting up the mac) my macbook so that i can save the necessary files before will lose them all.
    After that i popped-in my SL Installation DVD, and did the reinstallation process. Fortunately, everything works as charm and everything is back to normal after Spotlight has done it's hard work.
    Happy Apple user once again.

  • My MacBook won't start up.  After turn it on I get a grey screen with an apple in center and a circle below with lines around it and a blank bar below that.   How can I get it to get beyond this screen?

    MacBook won't start. After I power up, I get a light grey screen with an apple in the middle, a circle with lines moving around it and a blank grey bar below that.  It won,t get beyond this.  Please offer suggestions.

    I have the exact same problem and waited it out and got to my homescreen.  Whateve the problem is fried my bluetooth and my trackpad.  I tried starting it again and couldn't even get to homescreen, it stayed on the bluescreen with the wheel of death.  So, I took it to genius bar today. I was informed that my logic board is fried and it needs to be replaced.   $300 repair that I'm looking at...

  • After installing latest update Macbook won't start up.

    After installing the latest update my macbook won't start up. Instead of the login screen I get a flashing map icon with a question mark. My uncle says that means it can't find the startup disk and I had to startup from the install disk holding C but it didn't work. I'm quite desperate because I need my macbook for school (writing & producing music). I type this on a friend's computer... How can I fix this? Or do I really have to go to a mac store and part from my macbook for an unknown time...? :'(
    I don't exactly know what version I have (can't check it now either) but it's at least 10.6.something and I always install the updates...

    Hi
    Anything unusual happen during the 10.5.3 update installation phase?
    What type of iMac are you using? Your tag says G5 but also Intel core processors - it can't be both.
    Try this:
    -First unplug your computer and wait 10 minutes
    -Next, simultaneously reinsert the power cord while pressing the power button for 5 seconds then release
    -Press the power button again to start the computer - this resets the computer's system management unit (SMU) which controls your machines power functions.
    -Next, press/hold down the P/R/option/command keys for 3 Apple chimes. This clears the machine's PRAM. After the 3rd chime release those keys and immediately hold down the Shift key to put the machine into Safe User Mode
    -If you get to a log-in screen (may take several minutes as repair functions are occurring on the boot), log-in. When the login is complete, restart the computer as usual.
    If no go, I suggest taking the machine to a certified Apple tech, or if you live near an Apple store to the Genius Bar.

  • MacBook won't start at all - dead

    My MacBook won't start AT ALL - nothing, nada, zip.
    I press the power button and nothing happens at all - no sound, no lights, no movement.
    I have tried taking out battery and unplugging it, then pressing power button for 5 seconds, then inserting battery and plugging back in (as per Apple's kb note). This doesn't help.
    [OK I was trying to upgrade the hard drive - original hard drive is now back in the MacBook]
    Any ideas?

    OK I took my MacBook to the guys at Streetwise in Glenferrie Road, Hawthorn (we are talking Melbourne Australia here).
    Incredibly helpful - the genius there diagnosed a dislodged cable between the top board (keyboard and housing) and the main body. He thought I had dislodged it trying to change over the hard drive.
    In any case, he straightened things out, reseated the cable and voila, its all working.
    Hard drive upgraded too using Carbon Copy Cloner.

  • MacBook won't start on battery/shuts down when power adapter is removed

    Help & advice needed please.
    My MacBook won't start without external power, it gives a whir then a click then nothing. Once started up, if I remove the external power it just shuts off.
    The battery shows at 98% & charging. Coconut Battery shows the following:
    Current battery charge 4126 (& increasing as I type)
    Maximum battery charge 4200
    Current battery capacity 4200
    Original battery capacity 5200
    80%
    Battery loadcycles 111
    Age of your Mac 6 months
    Charger connected yes
    Battery is charging yes
    Does anyone have a clue why the Mac won't power itself on the battery when everything else seems like it works?
    Cheers!

    As of today, my MacBook and I have been together for 40 days. Yesterday, while I was happily surfing (on battery), it powered down with no warning. Okay, these things happen. I plugged it in, restarted, and all seemed to be fine. Battery was about 70%. I did other things on my other machines and when it was about 90%, unplugged it and everything was good. This morning after using it unplugged for 1.5 hours it did the same thing, but decided to only work with the power adapter, not on battery alone. When trying to boot without AC, it would try to spin the CD and then fall back into off. When on AC, if I pulled the adapter, it would last two seconds and go blank. I made an appt. with the Apple store (Fashion Show Mall, Las Vegas) for 3:20pm. I got there right at 3:20pm and the monitors showed I was 5th in line. Store was fairly packed, at least one patron at every display item. Monitors also said the next MacGenius appt. was "approx. 8:30pm." Glad I made an appt! I was served about 15 min. later, during which time the monitors had changed to "No more MacGenius appts. available today, please try tomorrow." However, one guy came by without an appt. and was told he would be put on standby and to come back in 30 min.
    Once I explained my issue with my MacBook battery, my Genius tried one of his batteries. "I just want to make sure it's your battery and not your motherboard." My machine worked fine, so he said "No problem, I'll have you out of here in 10 minutes." He got me a brand new battery, tested it, and put my old one in a box on the rear counter with four others. He pulled the serial number from the "About this Mac" area, didn't need my receipt for purchase date or anything. I had even printed this page: http://www.apple.com/support/macbook_macbookpro/batteryupdate/ to use as ammunition, but didn't need it. He did approve highly of my dashboard widget "iStat pro", available here: http://islayer.com/.
    So the battery issue is a very common problem, and one that Apple has tried to deal with as painlessly as possible for the consumer. My Genius did ask if the battery showed an "X" in the icon bar, and I said no. Just wouldn't run on battery. On the way out of the store, one of the 3 MacBooks, in fact the one closest to the door, had an "X" on the battery icon. When I unplugged the power, it shut down immediately! The moral of the story is to contact Apple immediately with problems and give them a chance to fix them. Hope this helps others.
