EliteDesk 800 Mini G3 65w
Microsoft Windows 10 (64-bit)

My system does not boot and gets the Hardware 3.4 post code.  3 long red 4 short white.  Manual says system board power crowbar or something like that.  I am pretty sure I need a new power supply.  Can anyone advise the right PSU and where to get it?

@smithsmith,

The crowbar is an electronic device. Unplug power cable from wall source.  Wait 1 minute. Then plug back into wall outlet. Test the HP. This is supposed to reset the crowbar.

The Power Supply part # is L2X04AA, as shown here and explain here on page 1 and 7.
