What if the notebook keyboard is flooded
If the notebook keyboard is accidentally flooded, it is easy to cause the failure of the whole computer. However, as long as the rescue is timely, there is still a chance to remedy it. Let's introduce it to you.
Cut off the power immediately and forcibly turn off the laptop.
When water or juice enters the gap of the keyboard, it will soon penetrate into the core area below the keyboard. If the laptop is still powered on, it will not only cause keyboard key failure, but also burn down the CPU and motherboard. Therefore, once the keyboard is flooded, please cut off the power supply immediately within 30 seconds and forcibly shut down to prevent the possibility of short circuit.
Turn the notebook upside down on the desktop for 5 minutes
The purpose of this is to make the water inside the notebook flow back a little, no longer penetrate into the core of the machine, and then continue to dry the keyboard.
Carefully wipe the keyboard surface with a towel with strong water absorption
Don't panic. Be calm. Find a towel or soft cloth with strong water absorption and gently wipe the water stains on the water entering keyboard. You can also prepare a bag of cotton swabs to wipe them in the subtle gaps to ensure that there is no liquid left on the surface.
Give the laptop a dry and ventilated space
Most people don't have strong hands-on ability. Some computers are still in the warranty period, and we can't unscrew the screws and dismantle the machine without authorization. Therefore, we just need to find a dry and ventilated corner, place the laptop with water in there normally, and maintain a drying time of at least 12 hours depending on the water inflow. The drying time is greatly affected by season and weather. Please don't be anxious, Wait patiently.
Solutions for severe water ingress
The laptop can be used normally. When some keyboard keys fail, you can buy an external USB keyboard to replace the original keyboard. If the whole machine has problems, it is recommended to send it for repair immediately.
How to repair the failure of individual keys after the notebook keyboard is flooded
Keyboard water is a problem that almost every student will encounter, so when the keyboard water or drink, how to solve it? Now let's introduce how to deal with keyboard water.
Check keyboard
① First remove the screws and disassemble them directly up and down.
② The soft glue under the keyboard key cap is the key to the knocking feel.
③ The core of the keyboard: matrix and control panel.
④ Finally, the cause was found: the matrix line was badly corroded.
⑤ Found traces of coke and determined that the culprit was Coke corrosion.
Solving process
① The copper foil strip is carefully attached to the original line.
② Cut the copper foil paper into strips, cover and paste it on the corroded lines. Because the matrix circuit is very close, if you are not careful, it is easy to cause multiple short circuits, resulting in abnormal operation of the keyboard, so you should lay a bottom with adhesive tape on the plastic circuit, and then stick the copper foil.
③ After walking a strip of copper foil, lay a layer of tape at the bottom Different sections and layers will not be too close to cause short circuit. After the covering and pasting is completed, use the universal meter to test again, and the normal path will announce the completion of resurrection. Reinstall the keyboard, and the familiar knocking feel returns to you again.
