Stick keys on a laptop
The reasons leading to such behavior of the keyboard are divided into two groups - software and mechanical. In the first case, we are dealing with embedded options for facilitating work in people with disabilities. In the second - with violations of key functions due to pollution or physical malfunctions.Cause 1: Software
In all versions of Windows, there is a special function that allows you to apply combinations not in the usual way - by pushing the necessary keys, and by pressing them in turn. If this option is activated, the following may occur: you pressed, for example, Ctrl, and then continued to work. In this case, the CTRL will remain pressed, which will lead to the impossibility of performing some actions using the keyboard. Also, the functions of many programs imply different operations when the auxiliary keys (Ctrl, Alt, Shift, etc.) are impressed.
Fix the situation is quite easy, it is enough to turn off the sticking. The example will appear "seven", but the actions described below will be absolutely identical for other versions of Windows.
- Several times in a row (at least five) press the SHIFT key, after which the dialog box described above will open. Please note that these actions (window call) may have to be performed twice. Next, go to the link to the Center for Special Opportunities.
- Remove the very first tank in the settings block.
- For reliability, you can also exclude the possibility of incorporating the sticking when repeatedly pressing SHIFT by removing the corresponding flag.
- Click "Apply" and close the window.
Cause 2: Mechanical
If the cause of the stick is a malfunction or contamination of the keyboard, then, in addition to constantly pressing auxiliary keys, we can observe a continuous set of one letter or numbers. In this case, it is necessary to try to clean the cabeorca tools or with the help of special sets that can be found in retail.

After dismantling, it is necessary to gently separate the film with contact pads and tracks, rinse with it with soap solution or ordinary water, after which it is possible to dry as soon as possible.
