Hello,
i see something strange with the motherboard DC/DC converter.
while checking voltages, i have somewhat low +/- 12V rails. i get 11.80 and -11.65V. thoses are usually around 11.90.
so, the mystery is here : if i bend enough the converter pcb in a way, all voltages raise (5, +/-12 they all raise ) and i can get a really strong 12V. if i bend it in reverse way, voltages fall...
it's not a connetor issue, i'm 100% sure. i tried to look, but i see nothing wrong. if someone have some ideas on what could happen ?
i thinked about bad ground vias, but i checked them, and they're good.
here is a little video of what happen : https://youtu.be/a5ZuQN6s7O0
if i can use my 2 hands for bending, i can get above 12V. i really don't understand what happen here, if it's an impedance issue, contact or whatever...
thanks
