Well, yeah I'm currently writing a writeup for the schematic. Well at least for me, since I already had a dc power supply unit to power my laptop, i needed some way to control the power to that unit and to the usb hub as well as turning on the computer and turning off the computer. I looked at the auto-on solution for laptops and thats cool and I also looked at how to generate a generic ups signal to put the computer into hibernation.
But, my laptop doesn't have a com port nor does it have a working battery. So, I had to come up with a solution that would do all the above, without buying another psu unit.
But, I'll prob post more info this weekend, when I get a chance to draw all the schematics and explain how it works.
