My Z440 desktop will not power on.  There are no lights or fans or anything at all.  I would like to test the 700w PSU with a multimeter to see if it has failed, but I need the pin configuration with the respective voltages to do this.  This isn't the first time I've had problems booting.  Could it also be a problem with the power button itself?  I tried to enter my serial number under my account, but this system would not allow me to do that.
