Even though water damage to the charging circuit is nearly 100% repairable, the circuit’s higher voltage ( 14.5V for MacBook Air, 20V for MacBook Pro Retina ) is still a great threat. By unplugging the charger, you turn off the charging circuit of the logic board.

The internal MacBook battery is still powering the Mac laptop at full speed if you did not shut down the laptop by holding the power button. Unplugging the charger alone will NOT cut off the power to the CPU and other important components. This step is less critical than the first one.
Unplug the charger if it’s still connected to the water-damaged MacBook. Now if you can quickly unplug the charger and disconnect the battery from the logic board, your MacBook still has a good chance of survival.Ģ. But most of the time the damage is minor. If the MacBook screen is still on (you can see the light) even you close the lid, your MacBook’s logic board is failing and out of control. Never open the lid to wake up (power-up) the laptop again. Your CPU, screen, SSD drive and RAM are all at safe hand now. In deep sleep mode, the logic board cuts off the power to the memory chips. Keep the lid closed for a while the MacBook will automatically enter into deep sleep mode. This design enables the laptop to be wakeup fast in normal use. In the shallow sleep mode, the memory chips are still receiving power. The MacBook then enters into shallow sleep mode. When the logic board detects the sleep sensor signal, it will cut off the power to the CPU, screen, SSD drive and most of supporting circuits. By doing so you effectively activate the hardware-level sleep sensor. Quickly use tissues to absorb the liquid that you can see on the surface of the MacBook keyboard, touchpad and screen, then close the lid straight away. Don’t panic, you still have other methods to shut down the Mac laptop. The keyboard cannot send the software-level “Force Shutdown" command to the MacBook logic board. If the water-damaged MacBook cannot be turned off by holding the power button, it means the MacBook keyboard has already stopped functioning.
