Macbook pro is not getting turn on and further when i press power button the green orange light suddenly changes to green again, moreover battery meter is not working

Hi
Last night my macbook pro gets off automatically when battery gets empty and in the morning it isn't turning on. When i connect the charger, the light on the charger turns green to orange (showing that it is charging) but when i press the power button it suddenly changes to green again. I thought there must not be any connection between the charger light and the power button. And battery meter was running fine.
When it tried this again and again the charger light disappear and battery meter also stops working, when i clearly observe it there is a very dim green light in the charger (not observable in the light) and the laptop is still not showing any change.
please help!

  • Macbook pro is not working with Canon pixma iP1500, but has previously.  The printer works with an old PC without trouble.  "printer is offline" message when this printer is plugged into macbook.  Any clues to get it to work?

    Hello Betty7,
    Please let me take a moment to say "Welcome" to the HP Forums.
    I hope you enjoy your experience!
    I see that you are having an issue with getting the printer reinstalled. 
    I suggest that we start off by running the HP Print and Scan Doctor.  If the Doctor fails, please let me know where it fails as well as any error codes it may generate.
    Thank you for your time.

    Don't use any cleaning spray. Wipe with a moist but not wet microfiber cloth.

    Hi - I have the exact same model as your MacBook and had a few questions as mine is acting up. I upgraded the ram to 8gb (2x 4GB ram) and ever since then my computer has not been running as smoothly and the start up time is horrendous. Have you encountered this problem? And if so how did you fix? What would you advise me do?
    I was thinking of reverting back to the original factory 4GB then rebooting the entire computer. Any suggestions?
    Thanks in advance!

  • Macbook pro had to be wiped out and I lost iPhoto (was free on the computer when I first bought it). Re-bought iPhoto but I can't find/get my photos.  Now what?

    Re-bought iPhoto but I can't find/get my photos.  Now what?
    iPhoto stores your photos in the iPhoto Library, by default it is in your Pictures folder. Double-click the iPhoto Library in "Pictures". Did you restore your documents and data, including the Pictures folder from your backup after the drive has been wiped?

  • The sound on my Macbook Pro does not work.

    The sound on my Macbook Pro does not work.  When we press the volume buttons, the sound icon pops up, but the bar is full with a small "Does not work" circle below it, and nothing happens when I hit volume up or done.  I went into system preferences, but there aren't any options there that I can see to change it. 

    "Unfortunately, it doesn't provide any help for a MacBook Pro, other than indicating to call Apple Support" (sic).
    Au contraire. TS1574's title and affected products are thusly:
    "Troubleshooting issues with no audio from built-in speakers on Macs
    Products Affected Mac mini, MacBook, MacBook Pro, iMac"
    As a result, the instructions of the article are relevant. To be sure, follow those steps, the last of which is to contact Apple.
    So, by way of reminder, here are the steps to troubleshoot the audio on your MacBook Pro. There is no red light, so the port is likely fine. Headphones work, so clearly your sound card is fine.
    1. Ensure an incorrect version of OS X is not installed. If one is, then reinstall or erase/install after backing up your data.
    2. Remove any external audio devices from USB, firewire, etc.
    3. Open Sys Prefs > Sound > Output
    If Internal Speakers is listed, select it and test again.
    If Digital Out is listed, confirm again that all external audio devices and cables have been removed.
    If mute is selected, unselect it.
    If the volume slider is low, raise the volume.
    If the above simply doesn't fix it, the issue may be a corrupted plist. Apple Support might be able to help troubleshoot the issue further, per the last step of TS1574.
    I hope it gets resolved for you. Good luck.

    Try doing a Parameter RAM reset - hold down command/option/p/r keys at start up and wait for three chimes before releasing the keys.
    If the hardware has filed there's nothing anyone here can do to help you ...

  • The sound on my macbook pro is not working

    The sound on my macbook pro is not working. When I increase the sound, the icon appears as if everything is working, but no sound comes from the speakers. Earphones don't work either. I have tried a PRAM reset but at times, this doesn't even work. It's really frustrating having to restart my computer every time I want the sound to work, and even when I do that, theres a 50 50 chance of it working again. It generally happens after my laptop goes to sleep and I wake it up. Has anyone else had this problem and fixed it or even know what caused it?
    There are a lot of discussions around the earphone jack but I have checked that. I've tried a PRAM reset which hasn't worked, and my sound output is set to Internal speakers.
    HELP!!

    Hopefully one of these steps should solve the problem.
    1. System Preference > Sound > Output > Internal Speakers
        Highlight  Internal Speakers / Headphones
        Make sure Mute is not enabled.
    2. Remove the headphone.
        If you see red light in the headphone port, plug the headphone
        in and out of the port 5 or 6 times to flip the microswitch inside.
        Sound output may be stuck in the digital mode.
    3. Reset SMC.     http://support.apple.com/kb/HT3964
        Choose the method for:
        "Resetting SMC on portables with a battery you should not remove on your own".
    4. Applications > Utilities > Audio MIDI Setup
        Audio Devices window
        Side Bar
        Click the Built-in Output.
        Under Mute any of the boxes checked? If so, uncheck it.

    Yuu can try to reactivate your iSight camera by opening up iMessage.. navigate to Preferences/Audio Video,and then click on Camera. IT shoudl be grayed-out if you only have one camera hooked up to your machine. If you have an external camera, then disconnect it from your machine.

  • ICloud sync with MacBook Pro does not work

    I've installed iOS 5, updated Lion to 10.7.2, marked Calendar and Contacts sync in System settings for iCloud on my Mac. However iCal and Address Book sync between iCloud and Mac (MacBook Pro) does not work though there is no problem in syncing between iCloud and iPhone. Whether I create new event or contact, change existing one or delete existing one in iCloud this change is not reflected on my Mac and vise versa. I could not find a solution in this site or in forums.

    Yep, worked for me, too and now contacts and calendar seem to be syncing perfectly.  We'll see if it lasts.
    Thanks for your answer.

    Here is YouTube's help page if you have no sound on YouTube videos:
