Re: not understanding the measurings I made on the K55VM board

Thanks for the reply, I suspect it could be something like that, I tried connecting a AA battery and the circuit draws 0,8A, couldn't find anything warming, there are so many caps connected in parallel it's hard to find the culprit, it could be a protection diode maybe... Must try with a power supply when I return to work bench, I was looking at the board at home with limited resources.
Anyway what I find strange is that the board was working fine from batteries, so the problem must be very close to the adapter...

Maybe someone can help as I'm not understanding the measurings I made on the K55VM board as follows:
the problem was that this Asus laptop was working on batteries and not charging. I took the board out and when measuring it seamed to exist a short to gnd in all regulator mosfets (drain to gnd and source to gnd) this can't be right as the computer was working...
I found that the A5 mos at supply input was in short circuit, I removed it from the board but I didn't put another one yet as I'm puzzled with this short circuit measure still found on the board.
Any ideas? What may...
