No Display + Angry Fan
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.
