Hi Team,
i got some weeks ago my brandnew PC with a AsRock Taichi X399 Motherboard. The first weeks the power LED on the front turned on by booting and shut off after shut down the PC.
Since maybe one week the LED is permanently on. I did not changed any hardware, just plugged an additional cable on my GPU the days before.
Looked in the BIOS settings but found nothin helpfull there to change the behaviour of the LED on shutdown.
Any help is appreciated and thx a lot.
Best,
Nic

Check if you haven't messed with the polarity of the LED cable.

Thx, but I could not imagine that a false polarity is the problem, because it worked before for weeks without changing the hardware. Seems to me like something in the settings has changed by itself (BIOS, WIN10, ?).

You are right. I worded my previous post badly. LED (or most diodes for that matter) simply won't conduct electricity when their polarity is reversed.
What I wanted to say is to check the power button cable, although is relize perfectly that that is a long shot.
I've never seen BIOS or a driver setting that could possibly affect this behavior, though.
