it's not the 5.5mm one, it's too big.

I think I found it: J7 in
http://hands.com/~lkcl/eoma/laptop_15in/pcb3/laptop_15in_PCB3_rev2_1.pdf
According to the bom it's "4.4mm Jack, 1.65mm Pin, Right-Angle, SMT, 5A
Rating"

that's the one, thanks raphael. it's rated for 5A so can do the job.
had to use 4.4mm because of the height clearance being restricted to
6mm or so. the standard 5mm jack (2.1mm centre-pin) is too high.

This is a bit off-topic, but I think you're confusing "ominous" with
"ubiquitous". "Ominous" means it foreshadows evil, or otherwise exhibits
a bad omen.

*dramatic-drum-roll*... :)

I stand corrected. Thank you.
If anything, the only connectors that are ominous are the proprietary ones!

mmm LCD is around 4. if you play an audio file at full volume it'll
take another 3W.

Oh interesting. If that's representative of other similar LCDs (and I
suspect it is) that explains why we don't really see laptops with e.g.
24-hour battery life regardless of how little power the CPU uses.

they're usually much much worse than that, and of course it goes up
on a square law. A 7in 1024x600 can be as little as 1.5 watts. 9in
maybe 2.5. this 15.6in 1366x768, it's very unusuall in that you can
run it at only 30hz and thus halve the power consumption of the
electronics part (at least), also because it's a lower pixel refresh
rate (because there's less pixels, duh) it's also lower power.
