Modern technology is very fragile products, and should be treated with care. But even the most accurate owner is not safe from such cases as the accidental fall of the gadget. After that, he may notice that a key is stuck on the laptop. What to do in this case?
Cause
Regardless of what happened with the laptop, the cause of technical sticking (the inclusion of the "sticky keys" function is not considered here) is always a change in the position of the platform on which the key is located. A laptop can be arbitrarily expensive, but the mounting system is identical in almost all - it can be compared with a wheel.
It also happens that for no apparent reason the key on the laptop simply crushed and stuck. What to do? Immediately carry in repair? No, you can try to figure it out on your own, the main thing is to be careful.
Dismantling a laptop keyboard
If you don’t have Internet access, you can first take a picture of the keyboard, so that later you can assemble all the buttons in the same order. To remove a stuck button, you need tweezers, a thin screwdriver or a paper clip. It is important not to exert much effort, because it can easily break the platform. Usually the button is easily detachable.
When the key is separated, you need to make sure that it is clean, not filled with any liquid (sugary drinks are especially harmful), and there are no foreign objects or debris on the platform. If any of the above is found, you should remove it, and then put the button back. As a rule, it is enough just to put it in place and squeeze it. But it happens that after such a procedure, the keys on the laptop keyboard still stick . What to do next?
Spring
The problem may be in the spring mechanism of the key. The platform is fixed with latches to the elevator, which has several moving elements and can be removed without difficulty. After disconnecting, make sure that the elevator mounts are working. If damage is found, you can try to take the elevator from a key that is rarely used: this usually helps. If the result is not obtained, it is easiest to buy a new elevator in a computer store.
Water and drinks
Often the reason why the keys on the laptop began to stick are spilled liquids on the keyboard. In any case, as soon as water gets on the device, you need to get it wet with a paper towel (toilet paper is also suitable) and immediately unplug it to prevent the internal parts of the laptop from burning out. Otherwise, serious and expensive repairs may be required. It is also possible to turn the appliance over by laying clearances with paper towels, or disassemble for further drying. It is worth paying attention that if the device is still under warranty, then after disassembly it will no longer be possible to contact the service for warranty repairs. However, filling the laptop with liquid falls under the item "improper operation", so repairs in this case, most likely, will still not be free.
It is not recommended to turn on the device during the day. At this time, you must remove all the keys and wipe them with alcohol. Why not turn on the laptop? Yes, if there was a little fluid, then it could well continue to work without any visible problems, however, any moisture that got on the contacts starts the corrosion process. The computer may fail quite soon, and the user will not associate this with coffee spilled a month ago.
Debris and dust, which are also the cause of sticking, is easiest to remove with a computer vacuum cleaner or a can of compressed air.
Less common problems
Gamers quite often encounter such a situation when a key is stuck on a laptop. What if this happened? Actually, the instructions are the same. Since the button is subjected to serious mechanical stress (in this case, frequent pressing or holding), you need to check the health of the mechanism and replace if it is broken.
Sometimes overheating becomes the reason why a key is stuck on a laptop. Not all users know what to do with thermal grease, so you can simply trust a specialist. If the owner is confident in his abilities, you should disassemble the laptop, clean it from dust and replace the thermal grease in all the necessary nodes. It is worth paying attention that, most likely, the possibility of repair under warranty will be lost after that.
If nothing helps
It also happens that for no apparent reason the button on the laptop suddenly stuck. What to do if the problem could not be fixed or there is no time for this? Indeed, when work is in full swing, there is not always the opportunity to be distracted by fixing the problem. The on-screen keyboard is not an assistant if you need to type many pages of text, so it’s easiest to connect a USB keyboard. Yes, this is cumbersome, but temporarily solves the problem. This will especially help if the laptop keyboard needs to be replaced, because it will take some time, and in the nearest computer store you can buy the cheapest external keyboard and calmly continue working.
System problems
Sometimes a simple reboot solves the problem with the keyboard on a laptop. Sometimes drivers are the cause, and in this case they need to be reinstalled. Drivers are best downloaded from the manufacturer’s official website, so the owner will be sure that he installs proven software. In some cases, keyboard problems can be caused by poor contact between the keyboard cable and the motherboard. On most devices, the keyboard is mounted on top with a few latches. They should be carefully detached, starting with the last one, remove / raise the keyboard, connect the cable, then return everything to its place.
On some models, in order to access the contacts, you will need to disassemble the entire device. The main tip here: be careful. Basically, parts of the computer are easily separated from each other, so you do not need to put extra effort so as not to damage them. You should keep all the screws, because in case of loss, buying the exact same ones can be difficult.
Most often, the owner himself can figure out why the key on the laptop keyboard sticks. If you are not confident in your abilities, computer masters will easily and quickly carry out any repair and cleaning of your device, the main thing is to contact proven services.
