Certain Keyboard Keys No Longer Typing

[hypnopaedia]

I am typing this message with much difficulty as the 'g' ',' and 'u' keys on my keyboard are no longer typing. It is a Logitech G510S Gaming Keyboard. I have uninstalled and reinstalled the drivers for the keyboard, as well as the keyboard's corresponding software and the Microsoft Keyboard & Mouse Center to no avail. I'd look to rule out whether or not this is a hardware-based issue. Any advice? Thanks in advance all.

The most common cause of this is that there is some dirt inside the keyboard located specifically in the keys that don't work. If you are handy with electronics and modest repairs of things, you can disconnect the keyboard and disassemble it to get to the contacts area for the keys. A common structure is that under the actual keys is a single rubber sheet lying over a printed circuit board that has metal contacts. On the underside of the rubber are a bunch of bumps with apparent black carbon faces. As you press a key, it forces the related carbon button down into contact with the metal on the circuit board, connecting them like a switch. Sometimes dirt gets into this area and prevents contact. In fact sometimes you can't see the "dirt" - it may even be loose carbon bits from the assembly itself. You can clean each carbon button GENTLY (they are thin and soft) by using a common pink pencil eraser to rub each one. Then use an artist's paint brush and a light blow of air to brush away any loose dust. You can do exactly the same - eraser and brush - to the metal contacts on the board. When it's all clean re-assemble and test it out.

The real trick in all this is understanding how the keyboard is assembled and kept together, so that you can be confident that you CAN disassemble easily (without breaking anything) and get it back together again. So if you try this, take it slow and easy.
