Okay so I figured out the power button.
Forget about trying to attach to the original power button, It just wont work.
Follow the ribbon to the connector, Lift the blue latch that secures the ribbon. Pull the connector up with the blue plastic leaf.
The connector is a "squash" connector, you just need to pop the two tongs on the left/right and pull out the clip (only half way) for the ribbon to come out.
Get a thin extension cable ready and put it on Pin 8 (looking at the motherboard from the front its the 8th pin from the right hand side, cut a few strands off your extension cable if its too thick).
Put the original ribbon back in. Ensure your cable is on Pin 8 and squash back on.
Put another cable under the middle screw that secures the keyboard down.
BAM, External power cable!
If anyone has any ideas on the dell power brick it would be appreciated! Two things I have thought of.
1. Sniff the data line and setup a microprocessor to emulate
2. Use the standard dell power brick and provide it the DC current it needs after the AC circuit.
If anyone has done this before (no point re-inventing the wheel) please let me know!
