Replacement uppercase just finished.
Il Mio Problema
My lovely daughter spilled a cup of coffee with milk over the keyboard.
La Mia Riparazione
It was a lot of work. You definitely need the right tools! Order them! The battery had to be replaced too after the first repair. I tried to clean the keyboard first. The removal of the battery was really terrible. Then I ordered a new keyboard. Tonight second time 75 steps and back to replace the uppercase. Success now.
