MacBook Liquid Damage can be extremely difficult to remove. Luckily, you can prevent some of the damage by performing the following steps prior to any attempt at repair.
1. Turn OFF the water-damaged MacBook instantly. This is the very first thing that you have to do when you spill liquid on your Macbook Air or Pro even before you place it in the bathtub.
2. Hold the power key for at least five minutes until the power goes off and then release the key.
3. DO not touch the logical board of the MacBook at all - only use the mouse. Perform your regular maintenance routine on the MacBook regularly. Clean out all the crevices, the keyboard crack, the hinges, the trackball, and the backlight of the MacBook with a soft cloth.
4. Clean out all the crevices in the MacBook with the damp towel and cloth. When removing the laptop from the water-damage, make sure that the keyboard, the display screen and the logic board are completely dry before re-connecting them with the USB cord.
The logic board of the MacBook consists of multiple tiny electronic components which are wired in close proximity to one another. With prolonged exposure to water, these electronic components get damaged and start to leak their respective liquid. In extreme cases, the entire logic board might get damaged and you would be left without a functional computer.
