Lambda Desktop Does Not Power On

Hello. We have recently purchased 4 Lambda desktops. I am setting up one of the computers, and I noticed that the computer does not power on at all when pressing the power button. I notice that the motherboard shows lights for the power and reset button though. Could you help me please?

I was able to resolve this issue by re-plugging in the battery of the motherboard: Lambda Quad: How to clear CMOS on motherboard (factory reset) - Technical Help - DeepTalk - Deep Learning Community. Thanks!
