What can I do if my laptop cursor jumps when I start typing? That question bothers many people who have certain types of laptops. There are several reasons why a laptop cursor jumps when someone starts typing. Most of the time, it is a hardware issue that you will have to deal with.
In newer computers, you will notice that the mouse pad is actually heat sensitive. That means the slightest touch can cause a mouse click to happen. When most people type, their palms and wrist can simply get close to the mouse pad of a laptop to cause a mouse click. This can cause a major problem when you are trying to type that 15 page assignment for school. However, most laptops also have a way to disable the mouse pad for that very reason. Most of the time, it is a thin button directly above or below the mouse pad itself. On some HP laptops, you will notice that there’s a blue light that will correspond to the button that disables the mouse pad. This can be inconvenient in the event that you forget to turn it on or off. It’s not far from impossible to highlight all your work, press delete, save it, and close it by mistake with this type of mouse. The safest route is to keep it disabled and use an external mouse.
On older computers, such as the Dell Latitude C600 or the IBM ThinkPad A31, you may run into this problem simply by the design of the mouse controller in the middle of the keyboard. There are times where the red or blue “eraser” looking thing in the middle of the keyboard can stick in a certain direction. This can cause the laptop cursor to move in that direction randomly or all the time. In this case, you may have to disable the mouse from the BIOS of the laptop. You can also try to disable it from the device manager which is located in the control panel of Windows. This also means that you will have to use an external mouse to replace the internal mouse.
