I had to opened the keyboard because the pad had a trouble since sometimes left work. So I saw that it was tartar in the edge of the pad. I take out the membrane in order to clean the contacts and the membrane... So now I don't be able to put the membrane in its place right. Is there some procedure in order to do it? The membrane is made of silicone ans it has little tips that it must go inside of the holes in the board of the keyboard.
I hope someone knows how put the membrane again...
Greetings
