  • Questions about powering Laptop

    ( Before someone makes a wise comment about reading FAQs, let me tell you that I've already done that and I'm still a little confused about the setup that I'm trying to do. )

    After getting dissappointed with Jetway and M2-ATX problems I've decided to go with a laptop for my new setup and following are the things that I want to have in my setup

    * Toshiba Qosmio laptop
    * 7" LCD
    * Powered USB hub

    Now the questions that have are

    1) What would be the best source to power the three devices ? I've looked into inverters and auto/air adaptors and the former one seems to be a better choise for laptop but how do I power USB hub and LCD ?

    2) Between an inverter and auto/air adaptor, which one is better ? Are auto/air adapters regulated ?

    3) If I go, inverter route what would be minimum power requirement that I would need ? (was looking at this one)

    3) Do all laptops power up with the lid closed ?

    auto air adaptor is dc-dc, much better than an inverter

    the lcd usually comes wit it's own dc regulator, & you could use a pol supply for usb like this for a simple easy setup...

    also, depending on the voltage the laptop runs on, you may be able to adapt a regular dc-dc supply too, & have that also control startup/ shutdown...

      Avoid inverters if you can.
      here is how i did my laptop:
      I used three separate regulators 5V (for USB) 12 V (for touch screen), and laptop Auto/air.

      My auto/air powersupply warned against being pluged in while cranking engine but I have tank circuit so it is not an issue.

      I'm using a docking station for the laptop,only issue is I have not hacked it to start laptop when I start truck, need to press button on docking station.
