    Hi guys, I'm experiencing this really strange and irritating problem:

    I just finished watching a DVD tonight, and was going to bed, so I selected the "shutdown" option from the menu to shutdown the macbook.

    However, after the macbook "shuts down", and after I was really to put the macbook to the laptop bag, the white indicator light for the sleeping mode is still flashing, so I thought to myself, ok, I must not have properly shut down the macbook.

    So naturally I tried to reawaken the macbook and properly shut it down, but long and behold, the thing just refuse to turn on, no matter how long I hold the power button, nothing happens. :mad:

    I followed the trouble shooting guide on the macbook user's guide, and on the bottom of the macbook the battery indicator is 4 lights, so it can't be the battery running low. And because the macbook is still in sleeping mode, I don’t know if it’s safe for me to remove the battery, as the owner’s guide suggests.

    What should I do?

    Should I take it to the Mac store? Even though I bought it online. I tried to call apple tech support (I have apple care, but it’s too late now they are off work).

    Thanks a lot for the tips and/or helps.

    I’m just kind of pissed since I like macs, and I expect higher quality than this form apple. :mad:

    I know you checked the battery indicator, but did you try turning it on while it was plugged in? If you watched an entire DVD on battery odds are that it is pretty low. Try plugging it in and then see if it turns on. If it does not, take out the battery and unplug it. Hold down the power button for 10 seconds. Put the battery back in, plug it in ad try again. If none of that works sleep on it and try it in the morning. If it still a no go, call Apple. HTH!

    We had this issue a few times here already.

    Basically you need to be sure that the white light is off fully before closing your notebook, Its kinda annoying but eh whatever. Anyways just cut the power and remember to do it right the next time.

    What Cashmonee suggested is called the PMU reset. Basically the steps are what he said.

    PMU Reset

    1. Turn off the computer.
    2. Unplug the power cord and unplug the battery.
    3. hold down the power button for 5 seconds.
    4. replace all the power components and start up again.

    Just remember to make sure it goes off fully. AppleCare will pretty much tell you just what Cashmonee said.

    I have a question:

    I asked the applecare person what's the possible cause of this problem, and she said that it's possible due to something about the logic board on the motherboard acting weird.

    so is there a possiblity of defects of the motherboard?

    It's a possibility, it depends on what week your mobo is built on, from what I've seen is that anything after week 30 should be free of problems. It could be numerous things really, but the motherboard one has been seen a bit.

    I have had the thing happen to me twice, however when it does happen, I always get closer to figuring out the causes and I believe I pretty much summed it down.

    Now, not all of them are gonna be motherboard issues, I have been getting the feeling that ejecting any media be it Flash Drive, CD/DVD, External drives and Monitor output if your using it, should all be removed correctly before shutting it down. For me personally I noticed it appears to happen when I DON'T do what I said above. Anyways, I've found doing it that way I really hadn't have any issues.

    Apple has a fair sized list of ways to counter this when it happens, such as PRAM reset, PMU Reset, Deleting certain plist files, trying a different power source (AC cord vs Battery) Permission repairs, and reinstallation of the OS X, as well as running the diagnostic software. If none of these fix it, than a call to AppleCare is warranted.

    When your display is off and the light at the front next to the IR port is off.

    i can almost promise you that it was most likely just not entirely shutdown before the lid of the machine was closed.

    what is Miku Hatsune, Budding?

    2 years late on this post but I had a similar experience.

    My macbook that had just turned 14 months of age, died on me last week.
    Similar to the story above, just that I was not watching DVD's - in fact, mine was a sparingly used machine - for some browsing, Skype etc. One day it would not start. Tried all the tricks mentioned in the manual - finally gave up and took it to the local Apple store.

    The chap at the Apple store was very quick to diagnose the problem with the Logic board!

    And he was right - according to the technical person who checked out the machine. The cost - £500! (Apparently, the Logic board costs £450!) (that values the rest of the macbook at £250)

    I am a doctor. When I diagnose a problem on listening to just the history, not performing a physical examination or some lab tests, usually the disease is quite typical and fairly frequent. If so, the macbook has an inbuilt flaw in its design and Apple are being smug - collecting the money for the repair - blaming it on the customer who has not taken out the exorbitant £199 insurance for 3 years!

    My guess is that the macbook has defects of the motherboard. Anybody else out there?
