Today I will remove and replace damaged keyboard on a Dell Inspiron 1525 laptop.
I’m replacing it because my customer spilled soda and some keys stopped working.
First of all, turn off the computer, unplug the power adapter and remove the battery.
Remove two screws in the battery compartment. These screws securing the keyboard bezel.
Carefully lift up one side of the bezel with a screwdriver.
Continue removing the bezel with your fingers. Be careful, there is a thin ribbon cable connecting the button board to the motherboard.
The cable has to stay connected to the motherboard.
Turn the bezel over. Make sure the cable is still connected.
Remove two screws securing the keyboard.
Lift up the keyboard and move it towards the display.
Now you can access the cable connector.
Let’s unlock the connector and release the cable.
On the picture below you can see the connector in the locked position.
Lift up the left side of the cable retainer with your fingernail.
Now the connector is unlocked and the cable can be released.
Remove and replace the damaged keyboard with a new one.
The keyboard part number is printed on the back sticker.
The Dell part number follows letters CN. In my laptop it was 0NK750.
