    Hoping to power laptop without soldering to power

    Has anyone had any luck with the various non-soldering laptop startup methods? I've read about wake from USB, Wake On LAN, Wake On Link and even separate hardware devices (xobyte). Can't find alot of success stories though...

    The main reason I want to do this is so that I'm able to pop the laptop (netbook actually, HP Mini 1030) out of my car at times... and not have wires hanging out of it.

    Looking at the Carnetix P1900 to power my netbook, USB hub and XM Direct... just want to see if I'll be able to auto-startup and shutdown.

    Thanks,
    Matt

    just another idea-- if you search through some electronic warehouses (digikey, allied), you should be able to find a small mating connector that you could use to do what you need, allowing the power supply to control the power button, and still have a removable setup that doesn't have cords hanging off of it...

    Thanks Soundman... is there any chance you could point me to a DIY or guide that uses something like this? Sounds like a great option, just not sure where to start!

    whats wrong with the xobyte solution? i don't see why it would have problems?
    sorry, if it was an obvious answer because i haven't looked much into xobyte

    I like the sound of the xobyte solution but its the cost that's throwing me... xobyte (~$150 to Canada) still needs a regulated power source. So I'm looking at a minimum of $300 (xobyte + Carnetix, for example) to make a go of it.

    Having said that, if people tell me that xobyte will 100% solve my problems I'll likely go for it. Just looking for real world examples of it working at this point....

    i have not been convinced that the xobyte solution is the universal best either-- while there are many boards that support WOL, i don't know if there is enough to guarantee that any future board that meets your needs will have it-- i know that WOL is not a huge feature for most people..

    i personally like hardwire solutions over data-packet solutions like the xobyte...

    for some ideas on type of connection, you basically need 2 conductors, the power button will not have any more then a very small amount of power that is sent through it, so there really isn't even a large concern over voltage/amperage ratings of the adapter you choose...

    you are really only limited to something with at least 2 conductors, and something that will fit in a small open space in the laptop casing... so let your mind run wild..

    my first idea is a headphone jack, but i have a similar one in my car like that, and the power gets shorted across the terminals when the jack is installed/removed... so this might not work the best for you..

    you could also use a rca jack..

    or you could use something like this:
    http://www.alliedelec.com/search/pro...px?SKU=6181840
    http://www.alliedelec.com/search/pro...px?SKU=6185001


    or items from this page:
    http://www.alliedelec.com/catalog/pf.aspx?FN=257.pdf

    or these(i use these all the time to control surveillance cameras):
    http://www.alliedelec.com/search/pro...px?SKU=5020693
    http://www.alliedelec.com/search/pro...px?SKU=5028718


    and being that the actual connector did not have a image-- see it at the catalog page:
    http://www.alliedelec.com/catalog/pf.aspx?FN=276.pdf

    and i haven't even gotten through a 1/4 of allied's connector assortment with these, and with a project like this, i prefer to look through the catalog, then try to search, because a search will only show you the things you can't use

    so start browsing the catalog(any pages before the ones i posted seem to have larger connectors then would be useful in a project like this) and see what you can find that you would be happy with..

    a solution like this would require you to add the port to the laptop, which would require drilling, cutting, and possibly glue, but with some careful selection, and well spent time, i have no doubt that you could come up with a solution that would look like it was supposed to be there...

    Sorry, the reason I posted so few links is because I really need to stay away from catalogs like allied-- going through my allied catalog, I am finding my old notes on parts-- last time I tried ordering, it was well over a $100 on parts that cost no more the $4 ea...

    and my wallet is still recovering from my ssd purchase...

    unless your laptop doesn't support WOL or you're planning to change laptop, i don't see why xobyte woudn't work.

    how i did it years ago was running the power on button to two pins of my modem ports (leaving the modem port useless, but i dont use it anyway) and connect a switch to that.
    back then it was manual turn on, but if you want to automate it, just have to buy a startup/shutdown controller trigger a relay and you've got a clean startup/shutdown method.

    Have you considered a dock? Permanently install the dock in the car and mod the power switch on the dock.

    On my Mac Mini, I soldered two wires to the power switch and ran them to two brass grommets mounted in the case. I attached the wires and filled them with solder. The case came in contact with two ballpoint pen springs that had the signal wires soldered to them. In 3 years of use in and out of the car, I never had a failure to startup or shutdown dye to that connection.

    Thanks for these ideas Soundman - I have no problem replacing the power button on the HP as its a pain as it is. Silly little plastic slider. Just so I understand the idea, the mating connector would trigger the laptop to power on when the ignition is turned (using a Carnetix P1900 as regulator)? How would it work when I take the laptop out of the vehicle? Can't get this part straight in my head.

    Bugbyte - I looked at a few docks but I couldn't really find a suitable one for my HP Mini. I did end up getting a USB hub that also has stereo in/out... but it doesn't have a power button.

    As for the solution you have for the Mac Mini, do you happen to have a photo handy? Sounds like a good one.
