XPS 410

Hi Slimmons,

Welcome to the Community.

The XPS 410 does not have a separate 2 pin connector for Power button LED. Please check this system board image which has Front I/O panel connectors labeled:

The Front I/O panel cables looks like this:

The main question I had was actually, which cable transmits the power on signal.  My power button isn't working, and I have no idea which wire goes from the power button, to the motherboard.  I see that the power button is integrated onto the I/O panel, but which cable goes from the I/O panel, to the motherboard to give it the original kick start signal?  I only have two three cables that I see should run from the I/O panel, the two pin temp control, the ribbon, and the usb cable.  

@dell-satya p, so, when I press the power button on the front, the signal to the motherboard that actually jumpstarts the computer, is sent through a ribbon cable?  

Hi Slimmons,

Thank you for the reply.

The cable image that I posted earlier connects the front I/O panel assembly to the system board.  The power button is fixed to the Front I/O panel assembly and there is no separate cable for the power button. Please check these images for better understanding of the front I/O panel assembly.

Second image shows the pins at the bottom where the Front I/O panel cable is connected.

The ribbon cable that  you are referring to connects the power button and USB ports in the front and this cable has to be connected to the Front I/O panel connector shown in the system board diagram.

This is the Intel website link which has more information about this system board and connectors:

Thank you very much for the response, that is exactly what I needed to know.  I just wasn't aware that the signal needed to power on could be transferred by a ribbon cable, but if that diagram is correct, I should be able to do more troubleshooting on the computer.  Now I have to figure out why when I had the ribbon cable connected, the computer didn't power on.  Thanks!

Hi Slimmons,

Im glad to know the information I gave was helpful. Thanks for confirming.

SLIMMONS did you ever find out what the problem with the ribbon was? If so, please tell me as I am having the same problem with my Dell XPS410. The only sign of life that I can see is the standby light on the mother board (Located beneath the GE Force graphics card). 

Shorted front usb ports can have this effect.  The fix is to replace the front panel board which is easy.  The +5VSB flea LED on the motherboard DOES NOT Indicate that the power supply is good.  Only that 20W of standby power is available. 

Sorry this is incredibly late, but I was never able to resolve this issue.  I ended up giving up, as it was taking an incredible amount of time to fix, for what would have been very little reward for me.
