    Opus 150 problems

    I've seached and cant seem to find a solution,problem is power supply has 12v constant,12v ign.,and a good ground.Green/white wires tapped into power switch on case(polarity correct). Green power led stays on but computer will not boot up. The hdd led lights up but not main power led ,if I manually press power button ,still will not power up.On a regular psu(110v) coputer works fine.I checked the ACPI settings in windows and they are correct to my knowledge.checked the bios and set up according to opus manual.What could be causing this any help would be much appreciated.

    give us your computer specs?

    it might be that it is drawing too much power for your opus 150 to handle...

    I have the Opus120, so this *might* not be the right solution, but I though the GRN/WHT wire is supposed to go from the Opus directly to the motherboard. You're not supposed to use the case power switch. Connect the GRN/WHT wire to the pins on the motherboard where you have connected the case power switch, and leave the case power switch out of the loop. The Opus should function as the case power switch (i.e. it does the turning on and off of the computer, no need to manually press any switch)

    System specs:

    Mobo- Epox EP-5VKMI socket 775

    Hdd- Maxtor 100GB sata 7200/8MB/sata 150

    Memory- 512MB PC2700 DDR 333MHZ

    Processor- Intel Celeron 2.93GHZ

    Drive- Panasonic slot load DVD-ROM/CD-CDRW

    Sound Card- Sound Blaster Audigy 4 internal

    OS- Windows XP-Pro

    Hope this helps.

    Also I only tapped into case power button wires so I could turn on comp.when ever I bring it in the house. I didn't think this would be a problem unless doing so can back-feed to the switch and cause it to shut down? I disconected the case button and still wouldn't power up.

    Okay, was just the first thing that came to mind... People here will suggest removing the sound card and see if you can get it to start.. Then, maybe replace the hard drive with a laptop drive if you have one to test with, just to see if you can get it to start POSTing and then you can shut the machine off... Removing parts one by one will help narrow down the possibility of your system requiring too much power. Also, not sure if your board can do it, but maybe try underclocking the proc, which will force it draw less volts, as a way of reducing the overall power consumption and see if that allows the system to boot.


    [EDIT: Also, you didn't mention in your specs, but how many (if any) USB devices are hooked up? Try removing non-essential USB devices for testing and see if that changes anything]

    I can underclock the cpu, as far as usb plug-ins there are 2, 1-touchscreen 2- remote for sb card.
    Also I had eveything disconected,just had power plug in and got 2 flashes,in house I checked polarity,checked bios, checked windows.
    So the only thing I can think of is using the xp disc to check acpi again through th setup per opus manual.

    see if you can get it to the BIOS screen without anything connected to it..
    just the monitor.. motherboard.. cpu and ram

    I suspect the SATA drive is what is putting you over the edge...

    I'll give that a shot,worse case use a power inveter ona home psu!
    In doing so would it be safe to extend the connectors about 3-6ft? Just asking cause therse no room under seat or in case for a big psu.Dont laugh to hard at the idea its worse case!

    well disconeted the sata hd and no luck still wont power-up,also i'm guessing there shouldn't be a small spark when power is pluged in.even after this the staus led stayed solid,when powerd off by key switch i get the same 2 blinks so i guess its time to get the xp disc. Also give me your opinions on my previous post since it looks like a route I may go. Thanks
