5/31/2024 update to resolve “Power Button Cable failure” warning during boot.
After watching this 3630 Case Swap YouTube video @stuffwhy found about a month ago, this was shown at approximately 8:13 in the video (Dell Precision T3630 to 7.3 Liters HTPC Case swap)
In the video he removes the power button from the front panel and solders the lead directly to the PCB contact, which would probably work significantly better in the small HTPC case used in the video, but wasn’t workable for my case.
Instead I spliced two dupont cables together with 2x female ends to plug into the board header on pins #8 GND and #9 DET as labeled on the 3630 mobo silkscreen.
For ease of plugging in my front panel cables I placed the female ends into a 2x2p Dupont connector housing and the male end into a 1x2p connector.
I also populated a third position in the 2x2p connector with a Dupont cable from pin #7 RST BTN and left the the fourth position open as the 3630 board header has no pin #10.
Here is a very poor diagram attempting to show how I wired things.
The 1x2p male ends will then plug into my case front panel reset button cable that would normally plug directly into the motherboard header (since pin #8 is GND it doesn’t seem to matter at all if it connected to the GND wire that is paired with the PWR BTN or RST BTN cable, at least for me.)
I then soldered the splice together and added shrink tubing to the wire assembly.
After testing continuity with my multimeter I installed the cable and powered up my NK6. I was greeted with no warnings or errors during the boot process!
Of course this isn’t strictly necessary to boot successfully since the BIOS can be set to not hang on the power button cable warning, as I covered in the original post, but I wanted to solder some stuff and already had way to many dupont cables and connectors laying around from past raspberry pi and other sbc projects.
