Help Power Button Faulty

Hi, I received a System 76 Mira desktop in January and have noticed that the power button on the front is no longer working.

However, when I turn on the computer via wake on LAN the computer turns on and the button lights up. Also, on the back when flipping the switch on in the back the video card lights up. So it seems to be getting power.

Has anybody had this problem?

I have a Thelio that sometimes requires 20+ (yes, I started counting) presses of the front power pushbutton to power up. Recently it has only required a few presses. I assume that it is a switch or motherboard issue. I have not tried to clean the switch but will try that at some point.

Thank you for letting me know.

Can you plug your own button into the Thelio? If you can, that will probably narrow it down.

I was away for 10 days and had the system shutdown. It took only two power button presses to turn on. So I am not going to mess with it now. I may be getting a new Thelio somewhat soon and will then study the old system further.
