Power light (?) stays solid yellow

Troubleshooting
1

I have a xenon project that I am working on and I decided it was ready for a breadboard. Long story short it is not complicated, but when I use the Xenon on a breadboard, no problem. If I use it with the citcuit board I plug it in and a yellow light (which usually just briefly flashed) stays solid yellow. Checked the traces and solder points for bad solder no deal.

What does that solid yellow light indicate?

Is it the RGB LED or the charging LED you are refering to?

If it’s the latter, you could have a look at this schematic to see what could potentially be the reason for the CHG LED to come on.
