Replacing the Entire Keyboard
If your keyboard has experienced a liquid catastrophe – a cat knocking over your coffee, a teenager spilling Mountain Dew or perhaps a baby spitting up – then you are probably going to have to replace the entire keyboard. The circuit board is highly sensitive and any liquid that gets into the keyboard will cause electrical arcing and cause irreparable damage to it. This Dell laptop keyboard repair is a bit more in depth and requires a small Philips head screwdriver, a small flathead screwdriver and a piece of tape.
Turn your computer off and remove the battery. Hold down the power button for 30 seconds to discharge any latent electrical charge in the system.
Pop off the bezel just above the function keys on the keypad. This is done by placing the flathead screwdriver under the opening between the function keys and the bezel. Slowly lift the bezel. You will hear a click, this is just the fastening clip being undone. There will be five to six fastening clips.
After you have removed the bezel you will see four (or five depending on the model) Philips head screws holding the keyboard in place. Remove these and place the screws on the tape so they don’t get lost.
Gently lift the keyboard out of its place. The connecting cord is still attached to the motherboard and pulling the keyboard too quickly could damage the connection point on the motherboard. Unhook the connection cord and discard the old keyboard.
Install the new keyboard in the opposite order. If none of the keys on the new keyboard work you may have inserted the connection cord upside down. If this is the case reinstall the keyboard with the connector flipped over.
