HP Recommended
Product: HP Pavilion 590-p0066
Operating System: Microsoft Windows 10 (64-bit)

I have a Pavilion 590-P0066 that will not power on.  Push power button and there is no response. No leds, no fan movement, nothing.  The problem has to be the power supply or the motherboard.

How can the proprietary HP power supply  ( L08262-003 )  be tested?

I will not "just buy a new P/S", as they are so expensive,  just to find out that the motherboard is dead.
