koby058 !!!!! No help for you till you can confirm the time for the next season of Fauda.

Ok - that is enough punishment and before I get banned by SMDFlea - check the voltage to ground of the PS_ID line. It is a common point of failure. This single line is used by the logic board (EC controller) to extract the details of your power adapter. Measure the voltage to ground on each side of the mosfet for this PS_ID line.

Hello Hello mon2,

We have a real time Fauda going on here thus no show

Do you mean voltage on PQ3801 ? if yes it is 3.3v and 3.29v

[mon2]

Yes, true. World is in chaos indeed.

Yes, PQ3801 - review that the PS_ID_R pin actually reaches the adapter connector pin. That is, we know that the expected voltage on this line is present but a physical break in the power connector jack could be the fault as was the case last week. Suggest to remove all power and use the meter in diode mode. Short the probe and you will hear a tone beep. Then confirm the same through the IO board that appears to be used on this model.

Hi, it was cheaper for me to replace the charging port now the issue is sporadic, I have tried the diod mode with no success, i can try again tomorrow, if any other idea i will be happy to try

I can also try a dirty fix jumper wire from dc jack to ps_id line if i can be sure from where to where
