    power and hibernation

    So I have my setup complete, but not the most efficient. I am here to try to figure out a way to incorporate a better setup to fix my hibernation problem.

    This is my current setup:
    battery -> switch (in dash to turn on/off power) -> inverter
    inverter has 3 ac plugs in which I am powering a home theater subwoofer, laptop, and usb hub.

    The dash has a 7 inch touchscreen which power/data/video is all through 2 usb cords. The touchscreen is connected by 1 extension to the laptop and 1 cord to the hub (the hub is powered). When the switch to control power to the inverter is on, the hub receives power and thus powers the touchscreen. The laptop is installed in the trunk. A push switch is connected to the pins of the power button for laptop and mounted in dash as well.

    Even when the laptop is off, the touchscreen stills has power. When I hit the switch to turn the laptop on, I need to wait some before the touchscreen gains control of the video, this is ok. But when I hit the switch again to hibernate the laptop, the touchscreen loses video immediately and starts initiating hibernate. While hibernating, I have no idea on how long it takes to complete because even though the touchscreen has nothing going to it, the power is still on. So, sometimes I don't wait long enough to flip the switches to the inverter, and the laptop shuts off during hibernation, which causes problems trying to turn it on again. The laptop doesn't have a battery (got it used without one for cheap) and I was coming here in hopes there was something I could do besides ordering another battery.

    I had the same problem, try this 2006 Acura TL w/Navigation Carputer Worklog.

    It allowed me to see when the power was off completely. You only need the power led. Also make sure to put 180ohm or 300ohms in line with the + side of the led for protection of burning it out (might not need it because the leds on board probably already has its own resistor I did mine as a precaution.

    Also I recommend you fork out some $$ for the battery I liked it much better and set it to standby/hibernation after 5mins on battery or when the battery hits 95%.

    about the only cheap option here is to extend the led's to see when the computer shuts off-- just as nguyen posted. just make sure to get the correct type, and voltage of led.

    this is exactly why it is a bad idea to use a usb screen as the main screen..
