Early 2008 macbook pro will not boot

Good morning!  Last night I was working on compiling some video footage from a DVD on my early 2008 MacBook Pro.  I put the computer to sleep with a DVD in the drive.  This morning it will not wake up and it won't boot--I never make it to the apple logo.  I do hear either a fan or the DVD drive for a moment.
Any ideas?  I'm kind of stuck here.  Thanks,Robby

Also hold the trackpad button down when you reboot so the DVD ejects.
If it doesn't eject, see this tip:

And note, any attached USB device may not support Energy Saver.  Keep those removed until you reboot, after putting the machine to sleep.

  • My Early 2008 Macbook Pro will not boot with anything greater than 3GB of Ram.

    Early 2008 Macbook Pro 4,1
    2.4 GHz Intel Core 2 Duo
    3 GB 667 MHz DDR2 SDRAM (PC2-5300)
    OS X 10.8.4
    Serial: W88450LR1XR
    I keep reading mixed reviews saying that 3GB is the max while others say this system supports up to 6GB.  I have tried both Kingston and Crucial and PNY and I get the same results.  I can have 1x2GB stick and 1x1GB stick but not 2x2 GB sticks.  Both 2 GB sticks work independently but they will not work together.  They are PC2-5300 667 MHz.
    I would really love to have at least 4 GB of ram in this computer.  Is it not possible? 
    Thanks in advance.
    Symptoms:
    If I put 2x2 GB in the computer and power it up, the little light on the front of the computer comes on but the screen stays black.  No post beeps or anything to indicate a failure or that it's running (except the light that comes on when I hit the power button)

    Ok - so no one is replying.   I just contacted Other World Computing who says that my Laptop will support up to 6GB of ram.  I just ordered the memory directly from them.   I have 6GB in the mail and should arrive tomorrow.  I will report that if their guarenteed ram will work.

  • My Mid 2010 MacBook Pro will not boot

    My Mid 2010 MacBook Pro will not boot regularly, in safe mode, in recovery mode or from original OS DVD. Is this the logic board?
    I've tried resetting the SMC and pram numerous times and even tried switching out hdd's to try and do a clean install on a new hdd.
    If I attempt to boot regularly or from recovery drive the grey apple logo appears for a period before the screen goes black and the power LED operates as though in 'sleep' mode. I'm unable to wake it from this state and the same applies to booting in safe mode.
    When attempting to boot from the OS DVD that was originally packed with the computer it just freezes on the language select option, this occurs with the other hdd's I have attempted to use.
    Any other suggestions to get it working? I fear the logic board has gone and that the repair won't be worth the money.
    Thank you in advance.

    Hi JRC8.8,
    It sounds like you have been on the right track in trying to troubleshoot this issue. You may want to see if your MacBook Pro will boot directly to the Apple Hardware Test, as outlined in the following article:

  • Macbook Pro will not boot beyond grey screen.  System freezes.

    My Macbook Pro will not boot-up or get beyond the grey screen (with spinning gear wheel.)  I've tried all the recommended actions: resetting PRAM, disk repair, permissions repair, re-boot in safe mode etc but still the problem persists.  When viewing the safe-boot in verbose mode, the system seems to hang at the stage when it's checking the Airport & Ethernet - the last line on the page reads: "AppleBCOM5701Ethernet:   0    0    setFixedSpeed - logic error, speed any?"
    Any ideas how to fix this without doing an Archive & Install?
    I'm assuming that if I do an "Archive & Install" then I will lose all my Applications (VLC, Handbrake, MS Office for Mac etc.)  Will this actually be the case?  Will I lose them.
    Any help gratefully received.  Many thanks.

    Archive and Install just affects the System files, so any apps you have  should still be available afterwards.  The Installer on the disk that  came  with your Mac, when you bought it, will tell you this before you  proceed.  Of course, you can always back out of the Installer if you feel chicken.
    Notwithstanding it is still necessary to backup everything.  You need to check that Time Machine is set to also backup your Applications folder.  It might be set not to do this. 
    It may not be necessary to worry about this if you have the original installer disc(s).  I think any stuff downloaded from iTunes etc can be re-downloaded.  However, it's probably quicker to get Time Machine to backup your apps if you can afford the HDD space.  It's bound to be quicker than re-downloading the stuff plus any updates.  And of course there's those Apps that you have but forgotten about.  What about them?

  • MacBook Pro will not boot

    MacBook Pro will not boot. Just get grey screen. When I hold down control + R, I get blank blue screen.

    Which model MacBook Pro do you have?
    It's COMMAND and R that will take you to your Recovery partion, not Control and R.
    If a later model, can you boot into Internet Recovery (booting whilst holding down the command, option and R keys)?

  • MacBook Pro will not boot after software update

    MacBook Pro will not boot after doing an Apple Software Update (of course they will not help you).  MONEY, MONEY, MONEY is the name of the game.  They can cause your computer to crash and still charge you! 
    Does anyone have an answer to why my computer is showing a little gear spinning for hours?  I have tried several things with NO luck.
    Thanks-

  • How do I uninstall Yosemite please ? Since I upgraded my 2011 MacBook Pro will not boot up

    My 2011 MacBook Pro will not boot up following my upgrade to Yosemite. How do I uninstall or downgrade back to the previous version of OS please ?

    You can't downgrade or uninstall unless you first erase the drive. Try the following:
    Reinstalling OS X 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 OS X: Select Reinstall OS X and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

  • HT203254 MacBook pro will not boot up?

    My 2007 MacBook pro will not boot up. Sometimes just stops booting before password screen, but other times after that. If I get to put in my password it goes on, but I either get a blank screen or partial jumbled screen. When using boot disc and run hardware test it gives a video controller error 4VDC/1/40000003. Would that make it hang up and not fully boot? I can understand it giving blank and jumbled screens.

    Means you need a new logic board. Make an appointment at an Apple store to confirm.

  • My Macbook Pro will not boot up. I can hear the sound that it has started and then goes into an infinite loop.

    My Macbook Pro will not boot up. I can hear the sound that it has started and then it goes into an infinite loop.

    What model MBP and which version of OS X? Sounds as if the hard drive may have failed. If you have an installation disc, try booting with it. If your machine came with Lion or Mountain Lion, try booting to the Recovery partition - Command and R keys held down while booting.

    Hi s.cheslik,
    It seems your MacBook Pro will not boot properly and it displaying an error message. Based on the information you have provided, it appears your MacBook Pro needs to be serviced. The following link should help you get started with the process and has links with additional information on topics such as warranty and service pricing, battery replacement, and express replacement service.

  • MacBook Pro will not boot up, stops at Apple logo

    My daughter's 3 year old MacBook Pro will not boot up. The grey screen with Apple logo comes up and it looks and sounds like it is going to boot up but after 30 seconds it goes black and turns off.  Any ideas or suggestions would be appreciated.

    The internal HDD will have to be replaced.  Since you cannot get the MBP to acces the internal HDD, you will have either use Target Disk Mode:
    http://support.apple.com/kb/HT1661
    Or take out the HDD and place it in an enclosure and then connect it to the MBP via USB.  (After you have installed the new HDD and the OSX)
    You may or may not be able to get information off of the HDD.
    Ciao.

  • MacBook Pro will not boot up. Hardware test found no problems.

    MacBook Pro will not boot up.  Hardware test found no problems.

    Sorry. What I mean is I selected the SL boot up in the start up panel and it would not boot into the cd. The CD rom sounds like it just keeps reading with it slowly loading from grey screen to blue screen to the Block screen. Almost like it is booting into normal mode from the hard drive.
    What I can't understand is why it runs fine is Safe mode?
    Also why do I get a " this disk cannot be used to start up your computer" message on my hard drive when trying to install Lion in safe mode? Well why not it's the only hard drive in the computer?
    The first screen shot is the Tech tool showing everything passed the hardware test is safe mode.

  • My macbook pro will not boot. It gets the grey screen with the apple until the bar is half way across and then shuts down. The only screen I can get to is in safe mode and I don't know what to do with that
