    Powering laptop

    How do you power a laptop to use it as a CarPC? Do you run wires from the battery back to the power adaptor of the laptop and power it that way? Or is there some other way?

    There are a few options, depending on the power requirements of your laptop.
    A car power adapter works well.
    There are regulators like the Carnetix P1900 that work well with many models of laptop (but not all!)
    An inverter will work, but isn't the ideal setup.
    Have you looked in the FAQ yet?
    How about the Wiki?

    By car power adapter you just mean a charger that plugs into the cigarette lighter?

    Lind power adapters

    I like the Lind DC to DC power adapters designed for autos. I use an automotive sytle relay latched by accessory power to cut fused 12Vs to the adapter. This then turns off the power to the DC to DC power adapter when you turn off the accessory power.
    The laptop will still be powered by its' internal battery (but won't drain the car battery).

    okay, say you use one of them, what turns the laptop off after you leave the car? wouldnt it drain your battery keeping the laptop charged?

    You can get a startup/shutdown controller for this purpose. You don't need one, but it makes life convenient.

    the best way to use a car adaptor with a laptop & no shut down controller is to simply wire the car adaptor to only have power with ign, then set the laptop to react with a shutdown or standby/ hybernate etc when on battery power for what ever length of time you choose. I've been meaning to write-up a comprehensive power guide for laptop installs for a while now, just haven't had the time

    So what would be better: powering laptop through auto-adapter or using Carnetix PXXXX ?
