HT3964 hi if my mac will not turn on, have unplugged, removed the battery, did control option and esc still to no avail help please

If a macbook pro will not turn on, the screen is black, have unplugged, removed the battery, have done command option and esc to no avail, also once battery was removed held down the power button for 5 seconds still no working screen,.  However when not  plugged in the green light appears on the bottom front  of the computer  and it stays green  after a few minutes it stays green then goes out. Help!!  .

In that case, the computer is dead, probably with a logic board problem. Take the Mac to an Apple Store to get your computer diagnosed and repaired

  • My iphone will not turn on after I replaced the battery

    My iphone will not turn on after I replaced the battery, itunes logo comes up, but it will not connect and does not reset! does anyone know what I can do?

    Who replaced the battery, you, Apple or an Authorized Apple Service Provider? If you did it yourself, then you could have done anything to disable it. It also voids any warranty and post-warranty support from Apple and the forum. You are on your own. If Apple or an Authorized Apple Service Provider replaced it, then take it back and have them check it.
    The iPhone does not have a user replaceable battery, or user serviceable parts. It is meant to only be serviced by Apple, or authorized service providers.

  • My ipod touch is not recognized on itunes and will not turn on or give me the battery sign. I have tried toubleshooting it by holding down the home button and the sleep/wake button, but it doesn't work. What do I do to fix it?

    My ipod touch is not recognized on itunes and will not turn on or even give me the battery sign that it is dead. I turned it off and it won't turn back on now. The screen is completely black and won't do anything. I have tried charging it over night and nothing happened. It was never near water. I have tried troubleshooting it by holding down the home button and the sleep/wake button, but nothing happened and it didn't work. What can I do to fix it?

    I would go straight to 5. Reset the SMC. If all else fails, bring it in, the PRAM battery may need to be replaced.

  • My iPod Touvh 4th Generation won't turn on. It will not charge even after I used a few chargers and will not connect to a computer. The Home button is broken and I don't know if the Lock/Sleep button is now broken or stuck as well. What should I do?

    My iPod Touvh 4th Generation won't turn on. It will not charge even after I used a few chargers and will not connect to a computer. The Home button is broken and I don't know if the Lock/Sleep button is now broken or stuck as well. I believe there may be a problem with the battery or the backlight. I've had my screen replaced once by some stooges. What should I do?

    Try:
    - iOS: Not responding or does not turn on
    When it  says place the iPod in recoverymode use one of these programs.

    RecBoot: Easy Way to Put iPhone into Recovery Mode
    If necessary:
    Download QTMLClient.dll & iTunesMobileDevice.dll for RecBoot
    and                                  
    RecBoot tip
    For MAC or PC       
    The Firmware Umbrella - TinyUmbrella
    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - Try on another computer                            
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

    I assume that you have installed new RAM in your MBP.
    It would be helpful if you indicated the EXACT model/year MBP that you have.
    What the the RAM specifications that you are trying to install?
    Ciao.

  • My macbook just shut off and will not turn back on, connected to the charger. Help!

    My macbook just shut iff and will not turn back on, connected to the charger. HELP!

    Hi there,... what color is the charge indicator on the charger connector? orange or green.
    Did you let your Air die from power?  Or has it been stored away for a while on a very low charge?
    What happens when you try to power on? nothing?
    If you cannot get to recovery mode and cannot power on at all, then its time for a service call to Apple for in shop full diagnosis and possible repair.

  • Upgrading to V4 has lost all of my Bookmarks, I still have the restore files in my profile data but they will not load, I have tried importing the html backup file too but it didn't work either. How can I get them back?

    Upgrading to V4 has lost all of my Bookmarks, I still have the restore files in my profile data but they will not load, I have tried importing the html backup file too but it didn't work either. How can I get them back?

    Ok this is bizzare!
    Thank you for your response, I went throught each and every step without any luck, even got the recovery programme, and painstakingly tried to sift through all that mumbojumbo to find what i needed. finally found the bookmark bit, but it had been fully overwritten :(, so on reading about previous ff versions, found the sqlite thingys, and they were relatively unscathed(partly written over, but saveable apparently TG), saved them to adiff drive, amongst other possibly good folders. Then looked up how to install them, and it said to close FF, and install to profile folder.
    So i tried to close FF, and the original problem from a few days ago, where it asked me if 'i was sure i wanted to close this window as it has X tabs open', popped up again. This is where 'open blank page' selection was set, over 'open previous tabs'. Wanting to save that info on how to sort out these friggin files, I reset the Option to 'open previous tabs', and closed FF. After unsucessfully searching for the profile folder on my laptop, i opened FF intending to search online for where i could find said folder.
    AND BANG, surprise surprise, the FF I had just closed with only tabs open about finding out what the heck to do, had disappeared, and instead my original saved tabs were up, and my bookmarks are there..... I am gobsmacked! what the heck just happened there???
    I have made 3 back up in different folders now, of those friggin bookmarks. I am weary now tho of shutting it all down.... what if its back to the other pages I had with no bookmarks, tomorrow :(
