    Remote power up of laptop?

    Hello all


    Well, it's drawing closer. My screen is enroute back to me, dash housing and all, and I am now wondering how I am going to go about mounting everything in the car and making it easy to use.

    My planned setup is using a Vaio laptop with my Lilliput screen in the dash and a keyboard for starters. I've been searching high and low for some kind of add on device that will send a wake up call to the laptop for power up. The way this laptop (PCG-F590k) is built, the switch is above the keyboard, not not accessible when the lid's closed. I'm interested in finding something USB or serial that will allow me to simulate the power button's function remotely, so I don't have to flip up the seat, then the laptop to get everything to boot.


    Anyone have any ideas?

    if your laptop isnt to hard to take apart try what I did:
    By removing only 2 screws on the bottom of my lappy I was able to gain access to the power switch. Then I routed a switch to my dash..

    using 2 small wires that are soldered onto the motherboard's switch and routed to the dash's push button switch, I can turn on and hibernate my computer from the dash.

    MoFo:

    Thank you for your detailed response - users like you keep forums alive. I've read many laptop users are doing this, but I have reservations about debauching a perfectly good laptop. I suppose it would be possible to wire in a connector of some sort so I can disconnect everything when I want to pull the laptop out. I've also had a few private discussions with another mp3car member with some ideas on how to handle the power aspect, and this may tie in nicely. My ultimate goal was to try to not open the laptop up to do any mods, in hopes of finding a way to initiate via WOL or WOR, or even better yet a USB signal of some sort that would turn on the machine.

    Another consideration is to use Hibernation mode, and merely shut off the inverter setup. I have a VW, which has constant power to 12v, and leaving an inverter on all the time will surely kill the battery. If I switched the inverter power, and use the Vaio's power profile to hibernate when on battery, that may solve the boot issue. Since we all know how wonderfully flaky Windows APM can be, this may be a problem as well. Argh!

    I'll rip open the laptop this weekend and see what I can see inside. Perhaps a little dremel work will make a new port (or remove the onboard modem port) for the switch. I'm still open to suggestions that will not require laptop surgery, so if anyone has anything other than "search" or "google" to add, please do so.

    MoFo:

    Heading to Dallas this week for business - you near the area? If so, let's hook up.


    Also, I'd like to see more pics of the way you mounted your laptop in the car. I got a glimpse of your cooling rack and the strap that holds it all down - and it's very close to what I'm considering in my car. I have the OEM port replicator for this laptop, and was considering using that for the external connections, thus making it easier to pull the machine when I need to without having to disconnect everything else. The power switch would be the only exception in this case. Sadly, I have limited space where I want to mount (under driver's seat - and I'm VERY tall), but I can make it all fit.

    another option is to do the whole "wake on lan" or "wake on ring":
    Shutdown/Startup Controller for laptop

    ...and another is just rewire the power button on your docking station.

    Spat:
    yeah you definately wouldnt want to run the inverter directly to the battery, it would be a hassle to take off and on all the time and if you forget..your battery is dead.
    I have mine wired to the amps which is wired to ignition, so it turns on with the key. I'm worried about one thing for you though...and thats the noisyness of the inverter. Mine is in my trunk so I don't hear it, but if you keep yours in your cabin, it may become a problem. Alternatively, some users use some kind of 'ITPS' device, but I havent researched that much.

    Also, I understand that you may want to be able to take your laptop in and out of your car. To solve that problem I wired the 2 wires from the motherboard to 2 jumper pins that I desoldered off an old motherboard. Then I connected that to a power switch jumper wire that I cut off an old ATX case, which I then connected to speaker wire (since it has 2 wires in one insulation) that I ran to the dash. This way I can easily unplug the external power switch at the jumpers.

    As far as my set-up goes. Yeah the fan pad makes a HUGE difference in keeping it cool. I used to have the laptop just chillin on the carpet in the trunk until on one hot TX day after an hour of use the laptop shut off due to heat. Now I have a USB powered fan pad thats drilled onto a piece of masonite board. On the bottom of board is velcro which keeps the laptop pad from sliding. And I use a $6 strap from walmart to keep the laptop secure onto the fanpad. Works flawlessly

    And also, yeah if your ever in Houston let me know and come on over. I'll order a pizza. I live SE of Houston, about 15 minutes from downtown.

    Heres a pic of the jumper pins incase i'm too confusing:
    (again with my blurry camera phone, sorry)
