Repair of Raytheon 911 notebook water inlet motherboard with short circuit and no power supply.
Visually, there is no corrosion where there is water. When the current is turned on, it is found that there is no current for a while, and it is concluded that there is a short circuit. When I opened the drawing, I found that the 8690 pipe PU21 and the PU23 pipe were passages. I directly removed the hot short-circuit pipe PU21 and re-burned the machine, and it was normal.
