This is usually a keyboard problem. Keyboard is a circuit made of silver oxide in flexible printed circuit board, which is easy to short circuit when it meets water. It costs about 100 yuan to replace the keyboard, but the keyboard is not the main thing. Don't take chances. If the machine with water is not treated, even if it is temporarily cured, there will be sequelae. Where there is water, it will slowly corrode the motherboard and chip, which is basically irreparable.

Don't open it again. The flooded machine must be unplugged from the power supply and battery as soon as possible. The probability of repair is closely related to the speed of power failure. It can usually be repaired quickly. If it is turned on frequently, the probability of repair is very small. If water enters, the motherboard must be taken out, washed with water, and then dried with a dryer to 100 degrees.
