Help - MacBook Pro won't turn on

Help - my macbook pro will not turn on even though it is plugged in. Holding down the power button is ineffective. The power cord has the green "charged" light, but when I plugged it in, it wasn't charged and never did charge (the light never was orange). The computer worked perfectly this morning.

Will it not turn on at all or do you just get a gray screen?
If a gray screen, look at this:

If it does not turn on at all, try a SMC reset:

If the reset fails to bring life to the MBP, make an appointment at an Apple store genius bar for a free evaluation.
Ciao.

    Reinstall OS X 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 this doesn't work then you will need to erase the drive and install Snow Leopard from scratch:
    Erase and Install Snow Leopard
    1. 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 Utilities menu.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
    4. When completed quit DU and complete the Snow Leopard installation.

    Depends upon what you mean by it not turning on, there are various causes.
    Is the power button pressed and nothing happens? Disconnect all other devices, then a SMC and NVRAM reset.
    Is there a white screen and nearly nothing? A hosed EFI firmware.
    Is there a grey screen and a loading bar that gets stuck? Either a failed firmware update or corrupted drive/OS X.
    Is there a grey screen with a spinning wheel? Bad third party or Apple at boot kext file.
    Are you loading but not able to log in? Possible corrupt third party software designed to startup upon login.

  • My macbook pro won't turn on without any reason?

    my macbook pro won't turn on without any reason, is there any solution in this case?

    You need to hit the "reply" button on post to whom your responding too, it's hard to tell if your responding to me or someone else.
    small button on the side of the computer and didn't lightting up( no reponse at all). is their any problems do think with the battery?
    Usually if your battery is dead because it wasn't charged you can do the SMC Reset and then check the Magsafe if it's connected and showing the orange light, then let the battery charge up.
    Once the battery charges up, the computer will boot normally and then you have to reset the PRAM, time, date etc.

  • My macbook pro won't turn on, any suggestions

    my macbook pro won't start up...it begins to boot up.but stops short before the screen comes on.  the light which indicates that the computer is on dims and the booting.stops.  any tips?

    I had this same exact problem from a couple days ago and it was fixed this morning, I remembered reading this and HAD to come back and help you. I left my macbook on all night and let the battery completly die out, after that I recharged it and it was back to normall. I hope this works for you as well!

  • MacBook Pro won't turn on and won't charge

    My MacBook Pro will not turn on and it appears to not charge. my charger blinks a orange light when I plug it in but the light is very dim. any suggestions?

    Bring it to an authorized service center and have them try one of their chargers on it.  If the charger doesn't work, then have the battery replaced.  If the battery being replaced doesn't charge, replace the power supply.

  • TS1365 My macbook pro won't turn on

    My macbook pro will not turn on. It was working normally and then I left for about half-an-hour to eat dinner. When I got back and pressed the power button (because I thought it'd just gone to sleep) nothing happens. I've tried pushing to power button a bunch of times but it doesn't do anything. I can hear the computer running though. It's also fully charged. I dont' know what's wrong with it.

    according to the article
    "If you are still unable to start up your computer after trying each of these steps, schedule a service appointment with an Apple Retail Store or an Apple Authorized Service Provider. If you plan to visit an Apple Retail store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only)."
