Good morning friends of the forum. This laptop is brought to me in the laboratory and they tell me that it has dropped water, plugging in the power supply gives no sign of life. Disassembling I find several oxidized spots behind the motherboard. I clean the whole board with isopropyl, rebuild some broken tracks and finally when I connect the power supply the power on led lights up but I have no image. I tried to reprogram the bios, reprogram the kbc, replace the ram but nothing to do. The absorption is 0.17A. I made some measurements:

PL8701 5,14V
PL8702 3,33V
PL9301 0,09V
