Outdoor cleaning is the easiest way to clean the keyboard on a laptop. It will be enough if your keyboard is working properly and the reasons for cleaning are rather preventive. This is done quite simply.

Cleaning the keyboard with rubbing alcohol is pretty easy. Most often, cotton swabs are used for this purpose. You just need to soak them a little in alcohol, and then wipe them on the surface of the keys and the space between them. For convenience, you can pour some alcohol into a plastic bottle cap.

  • After that, you can start removing the keys.

In this case, you need to be as careful as possible and in no case press on the keys.

The elevator fell

As mentioned earlier, the cover is attached to the elevators. If the lift is disengaged from the fasteners, then we will get a structure of two parts in our hands.

Such an incident can hardly be called a breakdown; rather, it looks like a construction set for adults. It is intuitively clear that the elevator must be returned to its place, and only then the cover. Don’t forget to Disconnect them. An elevator mount is usually made of a metal piece with two holes at the top and one wide at the bottom. Often they are deformed, then they need to be straightened before repair.

If the fasteners are in order, then proceed to the installation of the components itself:

  • There is a hole on the elevator where you need to insert a wide eyelet. The part needs to be corrected and lowered until the small ears are connected with the corresponding windows.
  • Everything should be installed easily. If the elevator key DOES NOT lend itself, then the matter is in the fasteners or incorrect location. Correct the situation and try again.

There is no way to return the broken mount to its place. If you decide to use glue, there are a few more keys to change. The best option is to start looking for identical analogs.

Replace the button

Let’s get down to restoration work:

laptop, keyboard
  • Examine carefully the part that has fallen off and the keyboard itself. If you DO NOT see any debris or defects, then the task is the simplest.
  • There are two grooves and two latches on the key cover. An elevator with two protrudes and two locks should have remained on the keyboard. Take a key, place it in its place and press down lightly until it clicks.
  • For high-quality fixation, it is necessary to act first on the lower part, and then on the upper one. If you did everything correctly, then the key will fall into place with comfort.

Gap dropped

It so happens that from the keyboard “escapes” key “space”, “Enter” or “Shift”. For such cases, there will be a little more operations. All these keys are equipped with a stabilizer, which evenly distributes pressing. The gimbal is the most common piece of stiff wire attached to the inside of the key. This wire has two ends, which must be inserted into special connectors on the keyboard, which are located on both sides of the elevator mount. Then the lid is installed in its rightful place, lightly pressed on it in the same order and fixed.

How to repair a laptop keyboard if both the cover and the elevator fell out? The task has become a little more difficult, but do not be afraid.

We repair the keyboard correctly

If you are still going to repair keys, then remember the following things:

  • Work only with a de-energized device. Remove the battery before work.
  • The keyboard design is usually the same on all models, so putting everything into place is not the most difficult thing to repair.
  • DO NOT use too much force during the repair, otherwise you risk breaking something.

How to fix a button on a laptop keyboard if it falls out?

The key is defective

Repairing a laptop key will only be necessary in cases where the keyboard has been attached with something hard. The lid may crack from such actions. The simplest way to solve the problem is to find a new identical part. But it is not always possible to find what you want.

If suddenly the cracks are insignificant and the lid itself does not fall apart from them, then we take glue for plastic in our hands and coat it in such a way as to hold it together. You need to glue very carefully, rub the composition evenly over the surface area.

There is another sophisticated way. to take the cover from another key of the same keyboard. You can take “

“Or another rarely used button. But there is one significant drawback. you have to get used to the new visual layout. Both of THESE methods help to resolve the issue temporarily. Better get the same cover.

What to do when sinking?

It so happens that the keyboard seems to be working, but does NOT behave properly. Here it’s not about buttons and fasteners, but about dirt that accumulates between the keys very quickly. If you are a lover of tea or coffee at the computer, then be prepared for such tricks. Have you already filled in the keyboard? Then it urgently needs to be disassembled and cleaned, but if you are late, you will have to look for a new one.

But it so happens that one button just sinks and does NOT return to its original position. The point is most likely in the elevator itself or the debris under the cover. We disassemble the keyboard, remove the blockage, dust it, dry it and check again. Most often, the simplest cleaning can solve such problems.
