    ok i got it.

    I suck at schematics but if you want one of these things let me know, email me.

    Since I have to buy so many things at a time I will sell some if anyone wants one.

    No big deal

    why dont you just grab power from the "powered on" LED. This LED is not affected by anything "software". Its ON if the laptop is ON and its OFF if the laptop is OFF. It will stay on even trough restarts and OS crashes. I have worked with a couple different laptops in the last few years and all of them have the power LED very close to the power button if not in the same place.

    In my set up I wired the power switch and the power LED. That way I have a remote button to turn it on/off plus the LED that gives me the status. I was thinking of getting the auto-power on module but its doesn't have a LED pass trough I want for status display. It shouldnt be difficult to wire the LED instead of using the laptops USB to tell if its ON/OFF and add a LED to the remote power switch of the module. One of those lighted switches would be awesome.

    ^ I like your idea of using a CAT5 plug and cable.... I used a molex connector and its clunky to plug/unplug... Good Idea

    the only thing to keep in mind when using CAT5 is that the wire is a little too stiff. I tried soldering the CAT5 wire directly to the LED but it would come out once the wire started to move and flex. I used a thin flexible wire and soldered it to the ends of the surface LED and then joined it to the CAT5 wire. The thin wire flexes really easy without putting stress on the solder joint on the LED.
    Soldering the CAT5 to the switch contacts was no issue though.
    Im sending the power button and the power LED trough the CAT5. It still has 2 more wire pairs available for future use, maybe I could send the microphone and the HDD LED. The color coded wires make it easier too.

    If you would have use stranded CAT5, you would not have had the problem with the wire being too stiff... Be-heading a pre-made 10ft cable would have worked well too..

    Props to you.

    gotta get me some of that stranded CAT5. I think we only use solid wires even for patch cables. If I find a factory made patch cable Im gonna cut it up and check it. Maybe after the 10 or 11th be-heading I'll find a stranded one :-)

    Here normally the 3ft to 25ft pre-made cables are stranded... and the supplier that I get my networking hardware from sell both Solid and Stranded RJ45 Connectors... So I'd think it would be common....

    Where do you live?

    Seems there was a misconfiguration with the international shipping. Should be all good now so give it another go. Thanks

    Additional Option

    I think I found another work around for the some folks (depends on the laptop). I would first start by looking into getting (if you don't have it already) the docking station for your laptop. I am using an HP NC2400 and it's dock. Instead of fiddling around and soldering my Laptop motherboard I decided to see if I could hack the dock instead. Mose docks have there own power switch which function the same way the onboaed switch does (while the machine is in the dock of course) Obviously this is a lot cheaper to replace if things go bad. So upon opening up my dock I found the the power switch and LED were on it's own standalone circuit board and wired to another control board within the dock. I clipped the wire at the 1/2 way point and plan on extending this wire by splicing in some of my own. There are 4 wires in all to control things like one touch standby or a hold down for complete power off...etc. I'll keep you posted on my progress if anyone is interested. Should take me a few more days to work on and test things out. Now I do understand that not all docks have the convenience of having the power button separate from the rest of the internal components, but that is where using an item like the one offered in this thread comes in...only this time instead of possibly ruining your $1500.00 laptop you are only hurtung a $50.00 - $100.00 dock. By the way using a dock has other benefits as well...Usually they have more USB Ports, and allow you to easily remove your PC from your car for safety / maintenence etc. without unplugging everything.
