There is a Dell laptop with LA-9104P REV: 1.0 motherboard which has disconnection and water was spilled on its controller. When water spills on this model’s touch pad, it causes a problem for standby controller (which is a common problem), which means in most cases controller gets out of order.
The other problem of this laptop is that by connecting power supply, it uses almost 5 ampere. This means there is a problem in main line of input voltage (19 volt).
3 different blocks of the motherboard had short circuit which we checked them one by one and solved all the problems.
In the video bellow you can see all the steps to repair this laptop.
