Titel:

MacBook Pro 15'' late 2011, not turning on, SIL blinks every 5 seconds

Tekst:

I posted this on apple discussions, but I thought I would try it here as well.
I have a MacBook Pro 15'' Late 2011, i7 processor. When ever I plug in the power cord (without pressing the power button), the sleep light turns on, turns off, waits 5 seconds, then repeats, the fans follow along with this cycle. It does the exact same regardless of whether RAM is installed, or not installed. NOTHING else turns on, other than the sleep light, and fans. It does this even if the screen is closed.
When the power cord is disconnected, you can turn it on pressing the power button, however, the sleep light does not turn on, only the fans. The fans turn on, then off, wait five seconds, turns on, turns off, then repeats.
What we have tried.
+
* SMC reset
* Removing RAM
* Changing RAM
* Using only one RAM slot
* Trying to turn it on with no RAM
* With hard drive
* Without hard drive
* With a different hard drives.
* Attempted PRAM reset
Not exactly sure what to do now. Any help or suggestions are appreciated.
