hi there, i'm assembling a new pc using an hp z400 motherboard. some problems occours.
1- the original power button cable ha a elettronic component (feel like a diod) and i haven't because i don't have the cable because i've bought a new case wich have standard plug e play pin.is that component necessary to start the pc?
2- searching and searching i saw thatthere is a hood sensor. is that sensor necessary to start the pc? how can i bypass thi sensor? (i'ts a normal switch, with two cable but at the motherboard i've 3 pins so i guess that the first and the third can be connected together to bypass an send a always closed signal to the pc

More research is needed... google "xw6600 pinout" and get the top Word document link that comes up..... I wrote that years ago.
Almost never was a hood sensor installed, and it has nothing to do with startup.
That is a thermisitor for ambient temp sensing. It feeds back into the motherboard fan speed control system, and is important.

That cable has multiple functions, including on/off, LED signals out from the motherboard, and it has an embedded thermisitor.
Download that document as a .doc file.... you'll find it valuable. Use this forum's search box up at the top left.... it searches only this forum. There is a treasure trove of answers for you there.

Try this, HERE.
Save it with the extension .doc and it is a MS Word file. Understand that this is not a HP file..... it is the result of a lot of people trying to figure things out and it will be a help but will not be perfect. Good luck with your project.
Here is the google top result from my computer......
