ok, thanks for the replies!
i tried doing the short on the 2 "power on" pins but it shuts off again
after about 3 seconds, i guess because it is suppose to be a momentary
switch! it sounds like the first option(shorting wires 14 and 16) is the
easiest but do i do both options to make this work?
having said that, i would like to make sure exactly what i'm doing here!
do i cut those two wires from PSU and connect them, or can i just use a
"paper clip" on the connector on the motherboard and jump these two wires
without any cuts? will that be a momentary switch action and bypass "power
on" pins all together?
thanks for all the help,
Kelly
