Take it apart and clean it up

A letter key in the keyboard is very inflexible, and you have to work very hard to press the key, this kind of problem, in fact, is quite easy to understand, and it may be caused by a foreign object entering your keyboard.

Here's how to deal with it:

After the keyboard is used for a long time, there is often a phenomenon that the keys are not working, in fact, there are many cases caused by excessive dust accumulation, as long as you are bold and careful in the repair process, you can completely solve it yourself.

1. Disassemble the back cover.

First, unplug the keyboard plug from the main unit, and turn it over to see the set screws on the back. By unscrewing all the screws on the back, you can remove the back cover. Note that there is also a screw hidden under the self-adhesive nameplate on the back of the keyboard, you can only see it when you uncover the self-adhesive sticker, it is often ignored by friends who dismantle the keyboard for the first time, of course, if you uncover this sticker, it is impossible to get a warranty again.

2. Remove the circuit board.

After removing all the screws, you only need to gently separate the two panels of the keyboard, you will see that there will be a circuit board on the upper left of the front of the keyboard, you can see some fixing screws on the circuit board, you must remove these fixing screws, carefully remove this circuit board, some keyboard circuit boards will have wires, do not use too much force to break it!

The structure of the circuit film is 3 layers, and if there is debris between the layers of film, it will cause the key to fail, so these 3 layers of circuit film are also the objects of our cleaning. There are no fixed screws on the 3-layer circuit film, they can be taken down directly, they are fixed through the round holes in the film, and the outer screws are fixed on the front panel through the round holes in the circuit film.

After taking off this circuit board, you can see that some frequently used keys will accumulate some gray layers, which is the crux of the key failure, you only need to use some soft dry cloth to wipe off the gray layer on it (such as a cloth for wiping glasses), and do not use water when wiping. There are 3 LEDs on the other side of the board, which are the Numlook, Capslock and Serolllock LEDs in the upper right corner of the keyboard.

3. Remove all buttons.

After removing the circuit board and circuit film, you can remove all the buttons. There is a separate rubber pad on each key, take them all off first.

4. Comprehensive cleanup.

Now that all the detachable parts have been removed, it's just waiting to be cleaned. You can use a brush to remove the small debris from the key destruction of the jujube plate panel, and then wipe it clean with a cloth. The 3-layer circuit film can also be cleaned in this way, the keys can be cleaned with water, or they can be scrubbed with a special surface cleaner.

5. Install it back.

After cleaning, follow the steps of disassembly to reverse the installation. One thing you need to pay attention to is to see if all the rubber pads are in their proper position to avoid misalignment when installing other parts.
