The mouse is jumping. There was one interesting case in my practice. For several years, no one could understand why not a single computer mouse worked at only one workplace. Nothing helped, neither adjusting the mouse, nor replacing it, nor reinstalling the system, nor even replacing the computer itself. I marvel at the patience of the elderly woman who works at this computer. How could she endure such, to put it mildly, inconvenience at work for so many years? The cursor was constantly in motion text editor it was generally impossible to install it on the required line, it was impossible to copy and transfer something. Files on the desktop opened and closed by themselves, it was enough to touch the mouse. Various specialists were called, but no one could do anything. And what interesting versions were put forward? And the malfunction was discovered to the point of banality simply ...

Why is the mouse jumping

I will tell you about what can be the cause of such mouse malfunctions and how to deal with them.

• In my case, everything turned out to be simple. Installing a program update on a computer with an enraged mouse, I accidentally touched a stack of papers and one of the pieces of paper lay right under my arm with a white surface to the top. I was in a hurry, and did not remove the paper, but simply continued to manipulate the mouse further.

After a while, I noticed that the cursor stopped jumping, and the mouse obediently did its job. So it was all about the surface of the computer desk. It never occurred to anyone that this could be the cause of the malfunction of the manipulator. We have a lot of such computer desks in our organization, and there were no such incidents anywhere.

Then I deliberately walked around the cabinets and carefully examined the surfaces of these tables. It turned out that only this table had a rough surface to the touch, and therefore the rays from the mouse were not reflected evenly. Hence these spontaneous jumps.

• First of all, you need to check the wire (if the mouse is wired) and the mouse connector. Gently without breaking the wire, run your fingers along it. Perhaps there are some notches somewhere. My cat is not indifferent to wires, and often bites the wire from the mouse.

• In other cases, such a malfunction may be an ordinary computer virus. Therefore, it is necessary to scan the system with an antivirus. It is enough for one Trojan to settle in some folder and your mouse becomes uncontrollable.
• It is possible that someone played a trick on you and installed a joke program that prevents you from manipulating the mouse.
• The mouse also jumps if someone local network or the Internet to your computer. Check if your computer is connected via remote access. The simplest thing is to disconnect the cable from the network card or turn off the Internet. If the mouse has stopped jumping, then draw a conclusion.
• There are specific mice that require a driver for normal operation. If you have such a mouse, then install or reinstall the driver for it.
• It is possible that a hair fell on the sole of the mouse directly under the laser beam. Turn the mouse over, inspect it and blow out the hole for the laser.
• If the mouse is wireless, try replacing the batteries.
• Place a special mat or thick white sheet of paper under your arm.
• Try replacing the keyboard. It often happens that the old keyboard somehow intercepts mouse signals.
• On a laptop, the mouse jumps when you hit the touchpad to enter information.
• Very cheap mice are of poor quality. Hence the cursor jumps.

These are the most common reasons why the mouse jumps. Check everything against the above list, perhaps some reason for your mouse jumps.

Probably, many have encountered a situation where the mouse cursor jumps around the screen when moving, teleporting to the most inappropriate places. Also, many came across cases when the wand cursor in a text editor, when typing, also jumps to another place and it turns out to be an abracadabra. Let's look at the reasons for this fantastic phenomenon.
The reasons are very primitive and there are actually few of them.

1. Mouse or keyboard malfunction, but this should be considered as a last resort after you have tried the following.

2. The mouse cursor jumping across the screen indicates that you are using a non-uniform colored surface as an optical mouse pad or simply crawling on the table. The fact is that the mouse indicator reacts differently to different shades of the surface color. Some shades for him may not be visible at all. In addition, uneven surfaces also make it difficult for the mouse to determine the distance you are moving the cursor. Different mice have different sensitivity to the surface. When buying, you can read about it on the packaging. The higher the resolution, the more smoothly and accurately the cursor will crawl and the more accurately you will be able to perform all operations (important when doing graphics). Resolution is 800, 1000 dpi, etc. (the higher - the more expensive and more accurate). To get started, do not be stingy and buy a branded rug with a one-color plastic surface. If the pad does not help, then the mouse itself may not be of a very high quality manufacturer (brand). Personally, I prefer A4Tech (good value for money), although there are many other good, but more expensive brands.

3. The second, most common, is the jumping of the wand cursor in text editors. On stationary machines, this occurs when people buy a new one. system unit, but saves and leaves the old keyboard, which may simply not dock with new equipment, as a result of which you may not only have a cursor teleportation, but also freeze with reboots.

4. For laptops, the problem of the wand cursor jumping in a text editor is the most common. There is a problem with the high sensitivity of the laptop mouse screen (TouchPad - also known as the touchpad). When you type on the laptop keyboard, you can accidentally hit the mouse screen, and as a result, it moves the cursor to a different location. The solution here is very simple. Connect an external keyboard to the USB laptop and you will stop touching the mouse screen. The second option is to connect an external USB mouse, and turn off the laptop's mouse screen and turn it on only when necessary. To do this, go to "Start" - item "Settings" - item "Control Panel" - icon "System" - go to the "Hardware" tab - click the "Device Manager" button. In the manager that appears, find the mouse in the list and click on the plus sign next to the device. If you picked up an external mouse, then you will have 2 of them in the list. PS/2 is that you have picked up external. Get on the second inscription - click right button mouse and in the drop-down menu, click "Disable". When necessary, also use the inclusion.
