Why I see electrical flash when I connect DC to DC-in
Original power adapter was damaged (burned down/circuit). New power adapter is not "visible" and it doesn't light either green or orange. I want to change DC-in card, the cable DC to DC logic board or the logic board but i don't know which one is damaged. I removed the cable DC to DC board and suddenly power plug started orange. It's not possible to run computer without DC to DC board so I reassembled the DC to DC board again. After connecting power adapter, power plug makes something like short circuit noise hearable in DC-in connector (i see also a blue electric flash in the DC-in connector) and after it doesn't light either green or orange again. when i remove the DC board cable (the 2 wire red and 2 wire black) cable from the DC-in card, the power adapter light orange....
Please help me with it because I don't know wich part is damaged ???
tks for your help !!
