I took this not asus Mortinho - no sign of led - it was only 19v at the entrance - I found this board layout .. analyzing tensions right away see the two input fets the first fet (M3024M) receiving 19v pins 5678 and already on pins 123 and 4 had 0.8ve the second fET (M3024M) on both pins were 0.9V - measuring the same, I noticed that the second fet was totally shorted between its terminals, I removed the plate to be sure, and it was 100% confirmed, it was short on killing all the stresses of plate - did not have another one like I saw that the fet was N-Channel, then replaces it with a well AO7702 N-Channel and not called back 100% |
