How to remove keys from a Samsung laptop keyboard. The process of removing the keyboard from a laptop with your own hands. There are two types of fixing the keyboard in the device

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 kinds 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:

1. 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.

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 with reverse side keyboard, this saved the laptop from leaking liquid onto the motherboard and helped it not burn out ( protective film not available 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:

2. 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. Buttons are placed in the following way. 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.

Like everyone else computer technology, laptops require maintenance and good cooling. This is especially true for devices with plastic case and a passive cooling system for the graphics and central processors.

If you do not monitor the temperature of your device, sooner or later this will lead to critical consequences, such as breakdown or complete failure.

In addition, computer keyboards of all types are often tested by all sorts of drinks, such as coffee, tea, juices or beer.

They also accumulate dust, crumbs and hair. All this not only interferes with ventilation and disrupts heat exchange, but also leads to breakage and “sticking” of the keys.

Why film Anyone who has ever tried to clean a laptop keyboard on their own understands perfectly well that doing this is not as easy as with personal computer . Because of small sizes device and saving space, as well as due to different types

fastening problems may arise.

• Removing the keyboard in a laptop, disassembling the device completely and disconnecting the cable from the screen may be necessary in cases where it is necessary to perform one of the following operations:

1. Solving problems with elevated temperature, including:
2. disassembling the laptop to vent the cooling radiator;
3. cleaning the fan from dust, hair and debris;
4. replacing thermal paste, which promotes better heat transfer between the processor and radiator;

• checking the presence of oil to lubricate fan bearings;
• repair or replacement of a damaged system configuration element;

1. solving keyboard problems such as:
2. cleaning the keyboard from spilled liquids, dust, debris and hair;

checking, replacing or repairing a damaged board or button.

Types of keyboard mounts

• There are two types of fixing the keyboard in the device: modern netbook and laptop keyboards are mounted on a special panel using plastic latches. Depending on the model and manufacturer of the fastening device, there can be from 4 to 8. In order to see them, you need to look very carefully, since they are well hidden so as not to disturb the design and device, and not disturb the user. Fasteners are usually marked with small notches. And this type of securing the keyboard in the device is the most common and complex;
• Less known, but more easily removed, are keyboards secured with screws. This applies mainly to old and rare laptop models.

As a rule, 1-2 screws are used for fixation. After unscrewing them, you just need to pry the keyboard panel with a sharp object.

Withdrawal procedure

After de-energizing your laptop, do not forget that its basis uninterruptible power supply, is the battery, so you need to take it out. Only then can you begin to study the type of fastening and other operations.

You can remove the keyboard in a laptop yourself. The main thing is to exercise maximum caution. The fasteners are very fragile and break easily. To get started, you'll need a pair of small, thin socket head screwdrivers.

If you have a common type of fastening, you need to follow these steps:

When opening the first latches, hold them with a second screwdriver or other thin object. Do not use your fingers or rush, as the plastic of the device is not very thick and can easily crack.

Disabling the loop

After disconnecting the keyboard, do not forget that it is connected. You can't tug or pull it. She connects with motherboard using a cable, which is very easy to damage. Therefore, this must be done carefully and correctly.

The cable is located directly under the keyboard and is attached to it using a special lock. These fasteners can be different types and require actions such as pinching the lugs, lifting the fastener, or lifting the spring latch to release.

If your goal was to replace the keyboard as a device, then the job is done.

If cleaning is needed

If laptop for a long time is in an open state, it may become dusty. During operation, a lot of hair, household debris and food crumbs get into the keyboard. If you need to clean up such debris, you can easily do it yourself by carefully vacuuming the device.

At the same time, the main thing to consider is that it is best to use a specialized vacuum cleaner with professional attachments and brushes; if you have to use a regular one, then you cannot use high power.

The keyboard is the main data input device. Most users like to drink tea or coffee while sitting at a computer or laptop, without interrupting work or entertainment. As a result, it suffers from damage from all kinds of liquids.

In this case, you cannot do without disassembling the device. It is necessary to dry and thoroughly rinse the keyboard, otherwise over time this will lead to “sticking” of the keys or complete inoperability of the device.

The process of removing a key from a laptop keyboard

If used carelessly or roughly, the key securing mechanism may break. To fix it, you need to remove the key from the laptop keyboard. In addition, you may need to remove the buttons if the layout does not match, or if necessary, wash or replace them.

There are two types of key attachments to the keyboard:

1. using two latching antennae;
2. rocker clamps with a hinge.

In order to remove the key, you need to pry it off with a screwdriver with a thin or curved tip or a bent paper clip; you can also use a crochet hook.

The lower part of the button needs to be firmly fixed with your finger, and carefully insert the tool you decided to use under the upper part; there are fastening antennae there; you can also pull the button up and slightly to the side.

The button may come off along with the rocker that holds it in place. It's not scary. Once the necessary repairs or cleaning have been completed, the retainer can be replaced in place.

For fastening, as a rule, three ears are used. If they are slightly raised and bent, they can be straightened using a screwdriver. Next you need to insert the rocker, and put the button cover on top, inserting it into the grooves.

If the fastening is carried out with latches, the button can be removed even easier. You just need to pull it up.

Removing the "space"

Wide and big buttons, such as “space”, “Shift”, “Enter” are shot a little differently and often cause problems because of this. In order to avoid distortions of large keys, special metal clamps and plastic guides are used to distribute the force when pressed. All large buttons are clamped with two latches.

In order to remove the “space”, you need to take into account the length of the button:

• lift it a little and bend it top part using one screwdriver;
• and the second one at this time unclick the upper bracket fixing the button;
• repeat the same steps with the bottom bracket.

After the button has been snapped off from the top and bottom, you can slowly begin to lift it, making sure that it has snapped off.

Installation after cleaning

When all the buttons are removed, they can be washed in a soapy solution or use a special liquid. If necessary, the panel can be wiped with wet cotton wool or a cloth, cleaning inaccessible areas with a needle or toothpick. You can use alcohol. After cleaning, you should start installing the buttons in place: just put on a regular small key, gently pressing on it and waiting for a light click.

But the gap is installed in three stages:

• it is necessary to install the button stiffener into the grooves on the panel;
• press the bottom of the key and connect it to the elevator;
• snap the button into the grooves.

If something goes wrong with your device and you spill a drink on it or just want to clean the dirty keyboard yourself, then don’t rush to contact a service center and pay a lot of money.

You can remove the keyboard from the laptop and clean it yourself, replace a worn button or a broken mount, at home and without a specialized tool.

There are several laptop manufacturers in the world, each of which makes its own unique design amendments to the device architecture. Some people use bolts to fasten the main parts, others resort to modern holding blocks. All this information is not of particular value to the user until the very moment when he does not have to face the need to disconnect some of its components from the laptop. And so in most cases it happens that it is the keyboard that needs to be disconnected, because it needs cleaning and minor repairs more often than other components of the laptop. And if you've asked yourself the question of how to remove a keyboard from a laptop, be prepared to learn some technical points, which you need to know before starting any manipulations with internal system laptop.

Laptop, like most electronic devices, using for their normal functioning an amount of electricity that is potentially dangerous to humans, must be de-energized before starting any work with its “internals”. After you have turned off the device itself and disconnected the charging cable, disconnect the battery. The device is now ready for disassembly. But to understand how to remove the keyboard from a laptop, you need to determine the type of fasteners specifically for your model.

As mentioned earlier, each manufacturer uses different methods fixing and fastening the keyboard. However, all options for how to remove the keyboard from a laptop can be safely divided into two conditional types.

The first category includes laptops that use several (four or more) bolts to hold them tightly. back panel computer. The second category includes laptops that use a system of fasteners that fasten individual parts. This makes it much easier to detach them individually. These two methods are most clearly expressed in the products of Acer and Samsung. Using their example, we will consider the process of disconnecting the keyboard.

So how to remove the keyboard from a Samsung laptop? First, you need to turn the device over and find the bolts on its back panel, under which the inscription “KB” or “KeyBoard” is often located. By unscrewing them, you will free the keyboard from the overall monolith of the system. Next, you need to turn the keyboard over and find fasteners in the cracks between it, which should then be pryed off with a thin screwdriver.

Having freed it from the fasteners and pryed it up with a screwdriver, you can begin the removal process by carefully pulling the plate with the keys to the side. Do not under any circumstances produce sudden movements, because the keyboard is still connected to the motherboard with a special cable used to transmit information. Lifting it slightly, find the place where the cable is attached to motherboard, then disconnect it (if you can’t pull it out right away, check the fasteners for the presence of small latches, like those you worked with when disconnecting the keyboard). When the cable is free, the keyboard can be easily removed without any additional effort.

How does “Acer” differ from “Samsung”, and how to remove the keyboard from an “Acer” laptop? There are practically no significant changes that distinguish the scheme for removing the keyboard from a laptop from the first manufacturer from a laptop from the second. You won't need to unscrew the bolts on the back panel, but you will have to tinker with the fasteners on the front, of which most Acer laptops can have quite a few. After you have dealt with the fasteners, you can begin to disconnect the cable, which will probably be secured with two latches, which, with proper skill, can be opened with your fingernails.

As you can see, the question “how to remove the keyboard from a laptop?” not that scary. You just need to know the sequence of actions, have a minimum set of tools, and not make sudden movements when working with fasteners and the keyboard, so as not to damage them.

Surely, many of us have encountered a situation where liquid was spilled on a laptop keyboard and individual keys stopped functioning. It should be said that keyboard repair consists of replacing it.
