What should I do if my computer cannot be used when the weather is humid?

You can use a hair dryer, fan, etc. to blow air inside the computer. If the weather is fine, take the computer outside to let it ventilate, check each component carefully, make sure the moisture has been removed, and try turning it on again.

In the future, you need to pay attention to the environment in which your computer is used and avoid using your computer in a humid environment!
