OK, lets start again, Please answer these questions:
- What is the color of the Mag-Safe plug? Green or Orange. When the system is off and does it get to Green.
- You had stated you might have been using the wrong power adapter. Are you using the correct one for this system (80W)?
- Open the system up and disconnect the HD SATA cable. Now restart your system what happens?
- With the internal drive disconnected, but only if you are getting the folder with the question mark displayed put in your system recovery CD/DVD into the optical drive is the system able to boot up?
- If you don't have a recovery CD/DVD do you have a known working USB or FireWire HD which you can connect (it must be externally powered for this test). Is the system able to boot up?
