"Be careful of food and drink around your computer". You hear this tens of thousand times. However, you accidentally knocked fruit drink or a late night glass of milk on your laptop or your child spilled a good portion of milk directly into your keyboard. You hear a popping noise, the screen goes black. Water by itself is not as bad as milk or juice, both of which are corrosive, or coffee, tea, soda, etc. As this DELL Precision M6400 Keyboard , it’s full of oil spots. This is not serious.
When you encountered this emergency, calm down and unplug the computer from its power source. Disconnect it from the power cord and remove the battery. Do not attempt to turn on the computer for at least 72 hours. Let it sit in a cool, dry place. Then, suspend the laptop upside down over a sink and see what liquid you can get to dribble out. Please carefully look beneath it to see if any juice got deeper into your laptop.
If it’s just on the keyboard, you can gently try to pop a key off. Many times, the keyboard area is further protected underneath with a rubber or plastic membrane. Clean up what you can. If they come off fairly easily, take a picture of the keyboard before you remove any more, so you know how to put them all back on. You can also lay them out on a surface, in order, as you take them off. Once you have access beneath the keys, clean all the juice out of the DELL Precision M6400 Keyboard with damp cloths and/or cotton swabs. Also clean the keys as best you can. If you have the picture of the layout, you can just throw them in a colander and rinse them off with warm water in the sink for a bit. You may need to take the keyboard apart further to get all the juice out of the various layers. Once you get it all cleaned up, make sure it is completely 100% dry before you start putting it back together. This may take 12 hours or more.
