Hi all, I have an Asus strix x570-e with some bizarre front panel problems.

The speaker, power switch and reset switch all works fine. The power and the HDD LED's on the other hand don't WORK at all.

I've proved that the LED's themselves work and reversed the polarity to no avail.

Things become more bizarre when taking a multi meter to the connector pins:

  LED      SWT   
(2+ 4-) (6+ 8-)           PWR
(1+ 3-) (5+ 7-) (9?)    HDD/Reset

According to the manual this motherboard follows the standard pin out convention but I get 5V across 2-1,  4-3 showed a fluctuating voltage, 0v across 2-4 & 1-3.

I thought maybe that the pin outs were supposed to be ROTATED but 2-1 retains 5v SOMEHOW when the PC is switched off (In shutdown state, not unplugged).


Does anyone have any thoughts on this?
Since you got 0v across 2-4 & 1-3, I wonder if the LED and SWT positions are switched.  Try hooking up the LEDs across 6-8 & 5-7 and the SWTs across 2-4 & 1-3.But the buttons work fine, just not the indicators.

If no one has any other ideas then I'll just hook the power LED up to a floppy disk molex(?). That appears to deliver 5v when the system is on.
