There are no leads to solder to, unless I'm really missing something. The reason I asked this question is that Thunderstick posted in one of the first messages in this thread that he had soldered these wires successfully in one of these PCs. I would love to see how he did it, because I see no way to do it. If this can be done on one of these machines, please, please enlighten me.

    I use a fanless system in my accord . And I have the same type of switch you have . If you are not good at soldering you might want to take it to a person that can. On the back side of the motherboard , where the switch, is 2 solder points that hold the switch there. That is the one you need to solder on. they are really small

    In my case , I soldered 2 one wire to each point and ran the wires to the rear of the case then installed an audio female plug on the computer case. then All I did is put the the male audio plug on the G & W of the P2140 . to be able to remove it. if you do this audio plug ideal. Buy STEREO plugs ( 3 connection ). and cut off the ground connection on both. Just use the 2 right and left connections. or it will never work.

    if you want to test it. To find the 2 solder points . on the back side of the MB. take a wire and jump the solder point right under the power button. be very " CAREFUL " . or you could be saying

    Really though soldering the power button may be the only option. Unless you can make it work with the wake on lan. Going in to standby shoudlnt be to bad as long as you are using a second battery and a battery isolator. This would allow you to use the USB shutdown and startup option efficiently.
    Newbie alert!! - How would I hook up the p2140 to a second battery and battery isolator (is this the same thing as a tank circuit?)

    Thank you in advance

    You hook it up the same way you would hook it up to a single battery system. Which is hooking up the primary input red wire to the positive terminal on the battery. Also, make sure you fuse the primary hot line the that connects to the battery with a 15A fuse also. Finally youre going to want to make sure your PSU is set to 12v for the primary line. You can do this by taking the top off of the P2140 and its a jumper setting. For more information refer to the user manual for the PSU. Thats really all there is to it.

    For future reference you should make a new thread with your questions instead of digging up really old threads, it usually works out a lot better. Good luck.

    Thank you for the reply, however I don't think I made it quite clear what I was trying to do. I want to hook the P2140 to my car 's main battery, as well as to a second "backup" battery. Is this possible with the P2140? If so, how?

    Thanks in advance

    Caretix dying?

    Hi I got a p2140 from the mp3car store lastweek. I followed this thread to install it

    http://www.mp3car.com/vbulletin/powe...-question.html

    I have 2 problems actually. First when I install the psumon it says application error 0000007f ... and will not start. I installed the dotnetfix but it didnt help. I installed it on another xp machine and it works fine. Now the bigger problem. The 2 round silver things near the 8 pin moldex connects is getting very Hot but the power supply works normal...just has that burning electronic smell. The dlyon is only registering 1.5 volts. Not enough to remote power on the amp. It powers the pc fine.Can you help? Do I need a RMA?
