Milk the keyboard

When the milk spilled over the keyboard, it was time to call upon the technician Mr Chan.

The keyboard had totally lost its control over the windows though the light was still on.

The connector was removed from the back of the CPU and the windows hung. Since this was predicted with the loose motherboard, the draft document was saved before anything was done.

The buttons were removed and placed accordingly to the arrangement on the keyboard. After some wiping of the under parts of the buttons, each button was dipped into a bowl of clean water and dried before fixing them back into the keyboard.

At this point of time, there were finally some reactions upon hitting the buttons; however, it seemed to have gone insane. The caps lock was on and off randomly and the output were different from the pressed buttons.

As the keyboard was lifted up, milk dripped down and it proved that the inner body was floated. Since the keyboard had no mouth, no CPR could be performed and therefore it had to go for operation immediately.

There were ten over screws at the back. After unscrewing them and removing the cover, the chip made of kind of plastic material with metallic things on the surface was dried up.

The rubbers that connected the buttons and the chip were removed and put into a new bowl of water. After a quick drying them, they were placed into the holes and then another wiping was done to make them drier.

As the cover was being fixed back, the last screw dropped into one of the hollow part and couldn’t be taken out. Therefore, another unscrewing and screwing process was carried out.

Finally the keyboard was in condition good enough to display some typing. It seemed perfectly alright until the “C” button was pressed and shown not working. So, the button was removed and the rubber beneath it was adjusted and then it started to work.

Everything was fine until when some buttons were pressed, the “D” character was included in the output. The buttons were removed and the rubbers were adjusted. The problem improved but certainly too little to decease the number of “backspace” I had to use.

Just when I thought it was a hellish day, I realised both the “Ctrl” buttons didn’t work. Nothing seemed wrong on the left button but the right one was flat. The button was removed and there wasn’t any rubber beneath it. Conclusion was that the rubber had moved out of the position during the fixing of the cover.

Since it was a long and tedious process again to remove the screws at the back and fixing it back, and the keyboard might not actually work properly after that, the technician gave up.

My elder brother passed me another old keyboard when he returned.
