Keyboard repair

Let's look at ways to repair keys on a laptop keyboard

There are two ways.

First way

If any fastening is broken, you can try to restore it using a needle from an insulin syringe:

• the needle is applied to the damaged part. It is better if it extends two to three millimeters beyond the edge of the breakage;
• Use a soldering iron to heat the needle and carefully fuse it into the plastic;
• Carefully bite off the excess plastic using side cutters.

Second way

If you don't have any tools, you can use superglue:

• heat the needle with a lighter;
• make a groove using lint from a comb or similar objects. The main thing is that the size of the groove allows the lint to enter;
• fix the lint with superglue;

On a note! The result can be checked in about an hour. Typically, the process takes about forty minutes to an hour.

How to care for your keyboard

In order for the device to work well and preventive cleaning to be effective, you need to follow not only the care tips, but also follow some rules of behavior when working with a laptop:

• do not eat or drink near the laptop - the trajectory of the spilled drink is unpredictable;
• do not place containers with water, such as a vase of flowers, near the device;
• Before work, wash your hands with soap so that the buttons do not get dirty;
• do not hit the keys - pressing the buttons hard does not affect the typing speed, and the keyboard may be damaged.

Now about the rules of keyboard care:

• Once every two weeks, carry out preventative cleaning: moisten a cloth with diluted isopropyl alcohol and wipe the keyboard. Alcohol will remove not only dust from the surface of the buttons, but also grease. You can use special napkins;
• Vacuum the keyboard with a special or regular vacuum cleaner. The second one pulls out debris more powerfully;

As laptop owners (and others) know, this small computer is susceptible to various external influences. After all, the compactness of a laptop and its small size, along with its convenience, are also a risk factor. For example, if on a desktop computer if liquid gets on the keyboard you can get by with replacing only the keyboard, then on a laptop you will have to replace, along with the keyboard, all sorts of components and parts of the motherboard and more.

In this article I want to describe a little the process of disassembling and cleaning a laptop keyboard after filling it with sweet liquid. The keyboard from the Samsung R510 laptop, which was drenched in sweet coffee, will act as a guinea pig, but the laptop did not lose its functionality, but the keyboard buttons began to stick. So, let's start cleaning: As many have already guessed, before starting the cleaning procedure, the keyboard must be removed. To do this, so as not to accidentally break anything, I recommend using special service manuals, which can be found in the instructions section (SG). Guided by the manual, remove the keyboard; to do this, unscrew the two bolts marked with triangles.

Next, remove the latches

and disconnect the keyboard cable from the motherboard.

This completes the removal of the keyboard and you can begin cleaning it.

The first thing that catches your eye is the presence of a protective film on the back of the keyboard, this saved the laptop from leaking liquid onto the motherboard and helped it not burn out (the protective film is not present on all laptop models). In order to clean the keyboard from coffee residues, namely sweet deposits under the buttons and on the contact layer, you must: Remove the buttons. To do this, from the back of the keyboard, use a small flat-head screwdriver and lightly press on the latch fastening.

When the latch comes off, carefully remove the button from the back side, moving it horizontally in the direction opposite to the latch.

The rest of the keyboard buttons are removed in the same way. When all the buttons are removed

carefully remove the contact pad (in this case, blue) and wash everything with alcohol.

The keyboard is assembled in the reverse order. The buttons are placed as follows. We engage the double-sided rotating mount (we removed it last) and lightly press the button until it clicks.

In order not to get confused in the sequence of buttons when assembling the keyboard, you can write down or photograph the sequence of buttons. You can also use the manual.

After these steps, the stuck keys will disappear.

Warning

1. A malfunction resulting from the ingress of liquid requires high coordination, accuracy and attentiveness from self-repair. Too much force or the wrong cleaning agent can completely destroy the conductive path. If you are not confident in your abilities, it is better to entrust this work to a specialist.
2. Removing and installing keys does not cost much (around 500 rubles), independent removal requires great skill, care and accuracy. Excessively sudden and careless movements can damage the fastenings. Carry out the procedures only if you have the necessary skills and are unable to take the laptop to a service center
3. The fastenings in small keys are also small. If you are not confident in your vision and the necessary dexterity, it is better to entrust the work to a service center
4. Working with a soldering iron requires not only care, but also knowledge, skills and experience. Careless movement can lead to damage to the entire device.
5. Superglue can get on the conductive path, rendering it inoperative. Work very carefully.
