Q: My macbook Pro will not start.

When my cord and adapter are connected to the wall outlet and my Macbook Pro the light blinks pale green and fast. I've tried my cord and adapter to other Macbook Pros and it works fine. When reconnecting the cord to my Pro it shines bright green for a few seconds after turning to red/orange. After a minute or so it then goes back to blinking pale green and fast. Nothing seems to help. Tried also holding down the startup button for long and short periods, as well as pressing several keys at the same time according to some suggestions. Please help!
