- Turn off the laptop and disconnect it from its power source immediately. Immediately detach the laptop from its power supply and turn it off.

• Just take out the charger cable from the laptop to disconnect it from the power source. Usually, it is on one of the housing sides of the laptop.
- Remove the laptop from any residual liquid. Get any leftover liquid off the laptop. This will reduce the amount of liquid that comes in contact with your laptop and lower the possibility of an electrical shock.
- Turn the laptop upside-down and remove the battery if possible. Invert the laptop and, if feasible, remove the battery. Typically, you may accomplish this by flipping your laptop over, removing a panel from the bottom of the device, and gently pulling on the battery.
• On some laptops, especially MacBooks, completing this step requires first unscrewing the bottom of the laptop from the remainder of the housing.

• USB gadgets (flash drives, wireless adapters, chargers, etc.)
• Memory sticks
• Controls (e.g., your mouse)
• The charger for a laptop
- Place a towel on a flat surface. Lay a towel out on the floor. Make sure you pick a warm, dry, discreet area because this is where you’ll keep your laptop for the next few days.
- Open your laptop as wide as possible and set it face-down on the towel. Lay your laptop face-down on the towel with the widest opening available. Depending on how flexible your laptop is, doing so could produce anything from a tent-shaped laptop to a flat one. You can direct a fan at the liquid to encourage faster evaporation in order to hasten the drying process.

A. You can usually locate online guides for your particular computer that describe how to change and remove hardware. Simply enter “RAM removal” and the make and model of your computer in a search engine (or whichever component you need to remove).
B. To begin, you must remove each of the ten screws keeping the base of the housing together on a MacBook.

• You should first remove any extra water that may be within your laptop.
• Do this with great gentleness.
- Remove dry residue. Get rid of any dry residue. To carefully remove any non-water stains, use a lint-free cloth. You can also use compressed air to remove any non-liquid residue like dust, grit, and other particles. 
- Let your laptop dry. Let your computer air dry. You should give it at least a day to be alone. 
• Think about keeping your laptop in a warm, dry location. For instance, a dehumidifier might speed up drying.
• Never use a hair dryer to hasten the drying process on your laptop since the heat it produces is strong enough to damage the device’s internal components.
- Reassemble the laptop, then turn it on. Put the laptop back together and power it on. You must bring your laptop to a reputable repair business if it won’t start up, there are sound or visual distortions, or otherwise exhibits any of these issues (e.g., a Best Buy tech department).
- Remove any residue if necessary. If necessary, get rid of any leftovers. You might have to deal with sticky or oily residue even if your laptop is operational. By carefully wiping the affected area with a damp, lint-free cloth, just like you did while drying the laptop earlier, you can get rid of this residue.
