Dell Latitude E4310 : Cursor Jump While Typing
You may fix this concern by disabling tap.
It seems that there is some hardware problem in your laptop. When there is any short circuit inside the keyboard these kinds of problems can occur. Deactivate your Touchpad and check the problem by using a Optical Mouse, and also check it by using a external keyboard. If the both solution didn’t work, replace your laptop before the situation gets worst.
This problem also happens to me whenever I reinstall the operating system of my sister’s laptop, an Acer Aspire 5738-663G32Mn running on Intel Core 2 Duo T6600 2.2 GHz processor. The laptop originally ships with its setup CD that contains different installers for various devices installed on the laptop. If your laptop also comes with this kind of CD, I’m sure you already noticed that there are different versions of programs for only one device.
When I first saw the contents of the disc, I got confused as to which of these programs should I use for the webcam, for example. My only solution, since there is no way of knowing which is the correct program for the laptop, what I do is to install each application one at a time like trial-and-error.
Just to know which one works. Like for example, for the webcam it has 4 different programs in there. For the touchpad, it also has 3 different programs. If the first version doesn’t work then it’s probably for a different model. I uninstall it then install the next one until I find the correct version.
You don’t actually need to install additional drivers for the touchpad like this one because the touchpad driver that comes with Microsoft Windows is already enough for the device to work. To have a possible solution for the touchpad, you need to uninstall all the software for the touchpad using the Add or Remove Programs.
I think it’s because of the different versions that are making the system extremely slow. After removing all touchpad applications using the Add or Remove Programs, check if the system will still make those sudden cursor movements. Your last option if this didn’t fix the problem is to reinstall Microsoft Windows.
You need to have the Microsoft Windows setup CD to do this. If reinstalling Windows still doesn’t help, you should bring your laptop to the qualified brand repair center.
