Ps4 pro will not turn on unless it's been plugged in outlet for a while

Ps4 pro will not start unless it’s been plugged in an outlet for a while. The eject button will work or atleast you get the beeps for no disc but the white light on power button does not come on or power up. Leave it plugged in the outlet for 44 minutes or so then press power button and it boots up. Not sure how long this is going to work before it won’t boot at all. Does any one know what might be the problem with this console? Power supply or maybe cmos battery? Thanks in advance for your help.
