1. Unplug the power supply and battery immediately. The speed of power failure directly determines the most critical factor for the severity of notebook damage. Do not start to shut down slowly until the system shuts down normally. If it is slow, it is quite dangerous.
2, according to the direction of the water, immediately pour out the water, and quickly dry it with a dry towel or paper towel. If there is water above the keyboard, immediately put the keyboard down (be careful not to let the water flow into the LCD screen), and drain the water as much as possible to avoid letting more water into the motherboard.
3. If the keyboard is flooded, take it out and observe whether the water enters the motherboard. Carefully dry the water on the front and back of the keyboard with paper towels. If possible, you can dry it with the cold air of a hair dryer. Be careful not to use hot air, because the keyboard keys are all plastic and resistant to high temperature. Don't use hot air to avoid being blown out. If the liquid is cola, vegetable soup, etc. You need to remove some buttons and scrub them carefully with pure alcohol. Because cola contains sugar, if it is not clear, it will corrode the circuit after a while, resulting in keyboard damage.
4, completely remove the motherboard, if you can't remove the motherboard, it is best to ask a friend who knows better to help remove it. Observe the motherboard for water stains, and if so, carefully wipe it with pure alcohol. I use first-class washing water to scrub the motherboard during notebook maintenance, but this kind of washing water is not available to most people, and it is hard to buy in the electronic market in Beijing. This is no ordinary washing water. This can be replaced by pure alcohol. Note 1: pure alcohol must be used, but water-containing alcohol cannot be used. Then blow dry the motherboard, or don't blow dry it with too high hot air with a hair dryer, and pay attention to protect the plastic connectors on the motherboard.
5. Carefully handle the moisture inside and outside the notebook case, put the processed motherboard and keyboard in a dry place for a day or two, and then make sure that all the moisture has dried before assembling it back. Do not turn on the power supply before processing. Because most users have unprofessional drying equipment, it is necessary to thoroughly dry all accessories as long as possible.
Sometimes, the laptop gets flooded. After the user shuts down and pours out the water, no other treatment will be done. After leaving it for a while, he opened it. Generally, there are two results at this time: one is that the machine can't be turned on, and the other is that the machine can be used normally for the time being. It is very dangerous to power this untreated notebook with water. If there is little water and it does not enter the motherboard and keyboard, the machine may be fine. But more often, after a few days or weeks of reuse, the notebook turns black again, or it can't be turned on or some functions fail. At this time of the notebook is quite dangerous, repair rate is very low.
The laptop just entered the water, because the water is the conductor, and the motherboard was short-circuited by the water, resulting in a crash or a black screen shutdown. At this time, it is just a water short circuit, and the components, circuits and chips of the general motherboard are not damaged. If it is repaired in time, it can basically be repaired, and there is basically no harm to the notebook. However, after the water enters, it will continue to be electrified, and after a few weeks, there will be failures and black screens, that is, cement mixed with water and dust will corrode lines, components and chips to a certain extent, leading to short circuit, disconnection and chip burning again, and often burn multiple components, lines and chips at the same time, instead of one or two components. At this time, it is very difficult to repair, which may leave many hidden dangers.

Non-Beijing netizens can also ask questions. Forget it, hehe. You can find me in Beijing, and other cities can find reliable maintenance points for maintenance.
