I'm going to have to pull this thing apart and use my crappy web cam, but here goes with what I can .......
Must also correct my previous post... it was a USN 1.8/10-D5R (has a sense line).
Datel pdf data sheet here
Here's the whole mod to my machine ...
Took the Ground (0V) connection to the Datel DC-DC converter from the big sqare mounting pad to the left of Q16/cap combo point.
ground point from here - black wire to DC-DC pin 6
Connected output from DC-DC to the lower left pad of Q16.
red wire to DC-DC pins 1 and 2
Then took +5V from the top pin of RV2, just above the USB port.
yellow wire to DC-DC pin 8
Trimmed the DC-DC UP to 1.95V by pulling the trim line (pin 10) DOWN to GND (pin 6) with about 16K (used two 33K's in // )
Also connected the Sense output of the DC-DC (pin 3) to the extra output line (pin 4).
The On/off line (pin 11) was left alone (it's internally pulled high).
Also cut off pin 5 to save any OOPS with GND to +V Out shorts.
Why did I use the 5V in part? coz it's all that Datel had at the time, plus the use of 3.3V in means you're regulating from an allready regulated supply (and I know that's also true of the +5V rail, but it's more likely to have more 'grunt' than using the 3.3 rail).
As you can also see it sits on top of the plastic SODIMM socket, and then wedges between the metal shielding when the whole thing is put back together. I also used pretty stiff single core wire which also helps stabilize it all too.
Seems to work good for me!
