The presence of moisture of any kind will affect your computer's ability to work properly. If a computer is used with water damage, the battery could short and cause a bigger problem with your computer's internal components. In addition, this could possibly overload your wall socket and cause a problem with your house lights, and even risk losing power. However, fixing a computer with water damage is not as difficult as one might think.

Skill level:

Things you need

  • Phillip's head screwdriver

  1. 1

    Unplug your computer from the wall outlet immediately. In addition, remove the internal battery from its housing on the bottom of your computer. To do this, you need to hold down the release tab located next to the battery pack and slide the pack free from the computer. This is very important so you do not risk getting shocked while trying to fix a water-damaged laptop.

  2. 2

    Open the computer by first removing all of the screws underneath of the laptop that hold the body together. Next, remove the two screws that hold the laptop screen in place. This will be located not on the bottom, but on the back of the laptop near the power outlet.

  3. 3

    Remove the hard drive from its slot by unscrewing the two screws from each corner of the drive and sliding it free from the computer. Make a note of the way you removed it, because if you put it back in upside down, the computer will not work. Check the hard drive for moisture. If moisture is present, press down with a towel to remove any immediate moisture, but do not wipe the hard drive as this may move the moisture around instead of removing it. Blow dry any additional moisture that remains.

  4. 4

    Separate the laptop screen from the body by gently pulling up on the screen until the two silver pegs have been removed from their slots. Make sure not to disconnect the two wires that lead from the screen to the motherboard. Separate the two halves of the plastic body to uncover the computer's internal components.

  5. 5

    Unscrew the metal plate that covers the motherboard and set it aside. Take pictures of the inside of the computer so that you will have a frame of reference when reinstalling all of the components. Start by taking an overview picture of the whole thing, then closeup pictures of the individual items.

  6. 6

    Disconnect the components one at a time and begin drying them in the same manner as you did the hard drive. After drying completely, let the components sit out overnight to air-dry as well.

  7. 7

    Reinstall all of the components the exact way you removed them, and refer back to the pictures you took in step 5 so that you are reinstalling everything correctly. Reinsert the battery pack and turn the computer back on. If nothing was irreparably damaged, your computer should be functional again.

Tips and warnings

  • If your computer will not work after completing these steps, you will need to take it to a computer repair service to find out which parts need to be replaced. Since you should now know how everything is connected, you can save money by simply buying the part and installing it yourself rather than paying the computer repairman to do it.
