Tried everything suggested regarding holding power button for 30s or more. I'm awaiting a new power button. Have tested without RAM, without harddrive, and without keyboard and still unresponsive. What else can I do to try and determine fault?
 
Solution
Have you tried....

1. Disconnect the power cord.
2. Remove the battery.
3. Hold the power button for 30 seconds.
4. Now plug the power cord back in.
5. If it starts up, put the battery back in.
