During the drying period, make sure your MacBook is not exposed to direct sunlight or sources of heat. Keeping the laptop in a cool, dry place will ensure that all of the water evaporates completely before you turn it back on.


In conclusion, Macbooks are not designed to be water resistant and can easily be damaged by liquid exposure. If thre is evidence of liquid contact or discoloration or corrosion, it is important to seek professional help for repair or replacement. Apple’s Liquid Contact Indicator (LCI) is a helpful tool in determining if the MacBook has been exposed to moisture and should be checked if any signs of liquid contact are present. Finally, proper maintenance and handling of the MacBook will help ensure its longevity and prevent issues caused by accidental exposures.
