    Thanks.
    Something must've been corrupted with the one I was using.
    Deleted the old one, re-downloaded it and all is good. No more hibernation problems

    I have a question, why did you use a relay when the psu acc can be connected to a switched power line from the car, doesn't this signal turn the psu on/off?

    I think i've answered my own question, the relay is there to allow for isolation of the carpc via the kill switch, if i take the feed from the acc on the ignition AND use the startup/shutdown facilities it will turn on and off with the ignition, if i'm going on short journeys or just switching the ign on and off i can flick the switch to isolate the carpc.

    Regards

    hi Me again!

    Decided to re-read this thread and saw the post re connecting the grey wire, can you confirm which pins you connected them to on the psu, was it G1 and G2 also if i use the advanced features when i remove the ignition switch, does the psu maintain power for a pre determined time (pot switch) then switch off the PC AND the feed to the PSU, i'm worried about battery draining.

    Hi Richie,
    I'll take your questions one at a time.

    The screen is powered from the vehicle Acc line.

    Yes, the relay is there so that I can run the PC independantly. Although it still needs acc for the screen, if I pull into a garage for fuel at least I don't need to shut down the PC.

    I didn't connect the grey wire in the end, but yes, G1 and G2 would go to the mobo.

    Battery drain was one of the reasons I used a switch.
    However, I accidentally left the PSU on (PC off) over a weekend with no ill effect so it looks like once the PCs off there's negligible drain through the PSU.

    Hey great write up. I have an SX280 which is slightly different than yours. I cut the cable between the AC PS and the Dell Connector. The colors are a little different. I see 3 black wires, 3 white wires, 1 thin blue wire, 1 thing red wire and exposed stranded copper wires. How do you think I should wire it up?

    Thumbs up All or None?

    I wanted to post this here. Are you also running your monitor as well as other toys(usb,gps,XM, ext drive) off of the PSU?

    my psu runs the monitor off a separate pinout on the psu boars and the pc is run via the mobo, all my extras run off the pc usb ports (gps DVD wireless TV ) and there seems to be no problem with overdoing the psu.

    Good Luck

    My monitor runs straight off the vehicles Acc line.
    The PSU runs the PC and all the USB stuff attached to it - I don't have XM radio.
