    Carnetix P2140 & Dell sx260/270

    Hi,

    I would like to use a Carnetix CNX-P2140 with a Dell sx260. In addition to the Dell I would like to also power a USB hub and xenarc 7" from the power supply.

    From previous posts, the Dell has a 150watt power brick.

    I have soldered a wire from the power button and extended them outside the case (for shutdown controller). I would rather use the standby feature than hibernating the PC. My install does not include a stereo and sometimes have to make a number of small trips. My car currently has in a Via M12K with a Opus 150 but need a bit more power.

    Will the CNX-P2140 work for this setup?

    It seems like it should, why not? I'm not sure if you can have three different volt outputs as you wanna do. But you can always power up the monitor from the car's supply.
    Seems fine to me.

    what wires do you connect to the power button and what wires are used for sensing the computer is powered on.

    How many volt does your Power brick work on now.?

    Right now P2140 can only out put +12V, +18.5V, or +20Volts .

    Mike is working on a way to upgrade the P2140 to be able to out put 12-20 Volts in 1Volt hops.
    He is doing it to be able to power the Laptops that are 14-18 Volts.

    Here is the Manual

    THis should work fine. The only concern I would have is leaving it in standby mode. Doing this will definitely drain your battery more than you want it to. I would suggest a second battery that is isolated after ignition is off thus preventing your main battery from draining and allowing your car to start.

    something to keep in mind. Most notebooks accept a wide range of voltages.

    The one in my car will work anywhere from 14-22vdc

    If its under 15 volts the notebooks battery wont charge. You have to get the technical docs of your notebook to see what it really supports and what's optimal.

    You can tell P2140 to shut down the Computer , then the Power supply at a set voltage. ( mine 11.2 ) . that way you can never drain your battery dead. And still start the car.

    P2140 default is ON & set at 11.8 when you buy it.

    one other thing to remember is that if P2140.

    can not produce 12 Volts prime and 12v sec. power outputs

    You Can only produce 12v on sec. output when you have higher then 12v on you Prime output.

    You can always just buy a small 12Volt power supply for just your screen.

    It sounds like you have the Laptop & screen running off one power supply.
