The power button not working in optiplex 360

I have a device dell optiplex 360 

I am facing a problem when I turn on the device, when I press the power button the device does not turn on, and the button does not light green or orange.

Months ago I got a message that the 2032 battery is weak and I need to change it. Do you think the problem is from the battery or what?

I will be grateful if you help me. Thank you.

Thank you very much for your reply

In your opinion, do you think the problem is from the battery (cmos)?

I will definitely change it, but I'm trying to figure out is there another possible cause of the problem to fix them both?

Two common possibilities: corrupted cmos settings or bad psu.  1st one easier and cheaper to test. Replace battery and then clear cmos settings by 360 motherboard RTCRST jumper. 
if still no power, use a verified working 24/4 pin psu to test motherboard.

if still no power, dead motherboard is diagnosis of exclusion.
