My customer complained that one of the keyboard keys stopped working correctly. Something got stuck under the key and it stopped moving freely. He had to push on the key very harder to make it type the symbol.
After keyboard diagnostic I confirmed that something got stuck under the right side of the key.
Here’s how you can take off the key cap and remove the stuck object.
Make sure the keyboard is turned off.
Very carefully start removing the key cap as it shown on the picture below.
Continue removing the key cap. The cap has to unsnap from the lifting mechanism.
Make sure the key hinges (lifting mechanism) stay connected to the keyboard.
As you see on the next picture, there is something stuck under the right side of the hinge assembly.
Carefully lift up the hinge assembly and remove the stuck object.
Position the removed key cap above the hinges.
Push on the key cap until it clicks back in place.
