I have this motherboard that will power on with the battery but give a battery not detected error
I thought one of the MOSFET had gone as I was getting 700 ohms resistance on one of 5 and showing 15v instead of the expected 19v - this made no difference.
I removed the battery and probed around, the mosfet is getting 19v but only 0.2v at the gate and source, the battery was giving me the 15v readings( lesson learned)
While the battery is disconnected the 3.3v and 5v is missing at the inductors - battery connected they are ok
Can anyone give me some advice on what to check - I have attached an image of the power input area and the voltages
Thank you
