Some keys on the Lenovo laptop do not work

The laptop keyboard does not work: the reasons and methods of solving

With desktop computers, if the keyboard stops working normally, they act quite simply. The input device can be replaced with another. Or disassemble, wash thoroughly, dry and collect. But what to do if the keyboard does not work on the laptop? You can’t turn it off, you can’t replace it without special knowledge. Even worse when not all keys work. This does not allow to write normally, blocks access to some functions. If a serious hardware failure has not occurred, to cope with the problem when the letters on the keyboard do not work without special knowledge.

Opinions on the Internet that some manufacturers put frankly low.Quality keyboards on their devices, absolutely far.Fetched. Modern sensors and processing chips are almost the same on all laptop models. Therefore, the reason why the keys on the laptop do not work can only be malfunctions associated with the features of operation. For example, this is:

• A hardware failure, to which even careless treatment can lead, throwing a laptop to a solid table, vibration during transportation;
• Software problems that often occur on devices with ports of the USB 3 class.0;
• The presence of a large amount of pollution.

Do not forget about the main reason why users most often contact the service center: half of the keyboard does not work after pouring tea, wine, beer and other liquids does not work. The basic rule of eliminating problems with the buttons sounds simple: not panic and carefully look for the root of the problem.

Next. Automatic search for updated drivers. If it’s not a driver, Windows 10 will report that the latest version of the driver is installed on the device.

To be 100% confident that the problem is not with obsolete laptop software and not with a conflict in the operation of individual components, we suggest going to the manufacturer’s website and update manually.

To do this, in the basement or in the menu of the manufacturer’s official website, find the Drive and Support section (drivers and utilities). Enter the model or serial number of the device, and update all the proposed.

Laptop power setting.

If the keyboard in Windows sometimes does not work, but after restarting the system begins to work again, try the next way.

The next step will be a check for viruses and other undesirable software installed on the laptop. To do this, download the Malwarebytes utility from the official website of the developer (free download), and start full scanning.

If you have a free antivirus type Avira, 360 Total Security or Avast, disconnect it. After cleaning the system from malicious programs, reboot the laptop.

It can also cause the laptop keyboard to work. In order to put the Windows system in order, install the free version of the CCleaner program from the official website.

Clean the operating system and restore the integrity of the registry in accordance with our instructions. After that, reboot the laptop.

Checking the train.

Do not fulfill this stage if you do not feel confident with a screwdriver in your hand. We will need to disassemble part of the laptop body and check why the keyboard does not work. One of the possible reasons is the train connecting the keyboard with the motherboard.

Open on YouTube video with disassembling your laptop model. Be sure to turn it off from the network and pull out the battery before starting work. Put on rubber gloves to exclude the appearance of static electricity. Photograph each stage of disassembly so that there are no problems with the assembly of the laptop.

Raising the upper part of the case with the keyboard, check if the train is connected. The fastening is short and is well fixed, but sometimes it falls (usually after unprofessional repair).

Separate buttons do not work on the keyboard

If any buttons on the keyboard do not work for no apparent reason, while others continue to act, then you should check, firstly, if you have Num Lock. If the problem is this, then the numbers on the right on the keyboard will not work, instead of them the computer will see arrows. Find the “Num Lock” button to the left of them (in the right upper keyboard) and click it. On some models of laptops, you need to press one of the hot keys (F3, F11, etc.) Together with the Function key (FN).

If other buttons stopped working. Check if the dust was packed under them, which prevents them from clicking. In this case, you should either well blow the keyboard with a special spray can, which you can buy in the store, or remove the keys, gently picing them with something thin (for example, a screwdriver) and wipe the keyboard manually.

Completely turn off the laptop and connect the charger. Click and hold for about 20 seconds the “Power” button until the charging indicator goes out. Next, just turn on the laptop and everything works.

As you can see, no drivers should be demolished/put, they did without indebions from toads and tears of virgins, but anyway, such a decision is such. I understand that this is abnormal by such shamanic actions every time conjure over the laptop, but the method is really working.

Lenovo did not find anything like this in the maintenance guide. By the way, who is interested in at the end of the article can find a link to him (not every manufacturer posts a full guide to disassemble his laptops).

I can assume that the Embeded Contoller settings are reset in this way. This is a built.In controller designed to control the platform (usually. Mobile) both at the level of turning on and off, and for processing the ACPIs. The tasks of the EC controller include maintenance of the battery of the mobile platform: selection of the mode of its charge, control of discharge. As a rule, on mobile platforms using the EC controller, the keyboard controller is also sold.

This is usually done by a disconnection for some time of the battery, but now almost all laptops are made with a non.Vegetable battery and in order to get to it you need to disassemble the case.
