    Your help is greatly appreciated.

    Life has been bad ever since my Macbook 13" (Late 2008) didn't boot up. After a few attempts I see that the fan is running furiously and the small white light that tells if the computer is sleeping is ON. ----- But there is ---- NO DISPLAY ON THE SCREEN

    So, the only things that look like they are working are the fan + light.

    What is wrong?

    Also, my macbook does not have a battery at the moment and is running on direct line in from the charger.

    Last night, there were a lot of fluctuations in the voltage which turned my computer off atleast 3-4 times.


    What should be done?

    Is this a fault in the OS? Or something with the Display driver?

    I see that the computer is turned on by the noise fan makes. At the same time the 'white light' is on(sleeping and awake?)


    Things that I tried -

    1. Resetting the SMC (http://support.apple.com/kb/ht3964)

    Resetting the System Management Controller (SMC)
    Resetting the SMC on Mac portables with a battery you can remove

    Note: Learn about removing the battery on MacBook and MacBook Pro.
    Shut down the computer.
    Disconnect the MagSafe power adapter from the computer, if it's connected.
    Remove the battery.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Reconnect the battery and MagSafe power adapter.
    Press the power button to turn on the computer.
    Result - Nothing happens. When I plug my Magsafe back in and press start - the white light shines on me whereas no sign of fan starting(is it even on?)

    But then I impose start for about 5-8 seconds, it starts with a slow running fan.


    What wrong am I doing here? Please help. I think this method has helped solve a lot of similar problems like this.


    2. Control + Command + Power up

    To check for any OS flaw, I used the fifth trick from - http://news.softpedia.com/news/Things-to-Do-if-Your-MacBook-Does-Not-Turn-On-133 615.shtml

    So, control + command + power = nothing, again.



    Please enlighten with some tips or tricks to solve this fellas. Your help is greatly appreciated. Good Karma shall follow.

    Do you still hear the chime when you boot it up?

    You could try to shine a flashlight behind the apple logo if you can see texts or whatever that is displayed on your screen. If you can still see it then it could be the backlight.

    Can you connect to an external display? (You might need a mini-DVI to DVI or VGA adapter though.)
