Question about HP (194989-001) (194989001) Power Supply
I need to use this power supply for other application but I d'nt know how
connect the pin to power on the output (I need +12 volt on).

I found the solution - and implemented it, it works. The blue (ID) line needs to show 7.5v. The simple way to acheive this is to simply put a 47k resistor from the +19.5v line to the ID line. Apparently there is a pull down at the computer end that means it ends up at 7.5v.
I cut the cable about 6" from the old HP power supply. I then soldered a female power socket onto the loose cable and soldered the 47k resistor between the ID line and the +19.5 line. I then plugged this onto my two pin power supply and the plugged it into my computer. It works very nicely.
Not wishing to junk the HP power supply unecessarily - it was still producing the 19.5v - I then soldered a power plug onto that ignoring the ID line. That now works as well. It seems that the circuitry that provided the 7.5v ID voltage in the HP power supply became flakey. I could have just opened up the power supply (I have already done that) and disconnected the blue line from the circuit board and just tied it to the +ve line via the 47k resistor and then wrapped it with the usual insulating tape.

You're asking for a fire or just burning out the power supply. But,at your own peril, check the yellow wires for 12v or buy a power supply test adapter from ebay. It bypasses the power switch usually done by the motherboard & will fire up the power supply like it was connected to a board. Then test the wires for 12v. Should be any yellow wire,red is 5v. Green is 3.3 or 3v.
