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.

The basic rule of eliminating problems with the buttons sounds simple: not panic and carefully look for the root of the problem.

Some keys do not work

The keys of the right block of the keyboard failed. In this case, do not rush to the master or start to disassemble the laptop.

A common cause of failure is a random shutdown of the Num Lock function, which leads to blocking this part of the keyboard.

To find out whether the Num Lock is turned on, you need to check the inclusion of the indicator (has the designation “1”): if the light is burned, the function is active, if the backlight is absent, it is necessary to press on the corresponding key.

  • The most common cause of this error is the pollution of the keys. The problem is easily eliminated in the process of cleaning the laptop. A distinctive feature of the device pollution is the need for a stronger press to work a certain key.
  • The problem can be associated with the wear of the device: any key is designed for a certain load (usually about 50 thousand presses). Over time and with active use, we wear out thin wires and closing paths, acidification of conductive contacts. With this reason, the most used keys refuse the most used keys.
