Uncommanded Cursor Jump

go to control panel / mouse to open the mouse properties window. along the top of the window should be several tabs. select the tab for touchpad or maybe advanced properties. this tab allows you to adjust the touch sensitivity of the mousepad, momentum, and other properties. adjusting to make it less sensitive may reduce the tendency of the cursor to jump or move on its own. failing that, go for an external mouse!

You may want to consider disabling the touchpad all together while typing for extended periods.

Depending on the sensitivity and settings of the touchpad, it may register undesired motions as mouse controls, causing the cursor to jump erratically. The software drivers that includes with its systems have sensitivity options that help alleviate this problem and ensure that only deliberate touchpad motions and taps cause the cursor to move.

Click on the Start menu and open the Control Panel. Choose an "Icon View" option from the "View by" dropdown menu, then click the "Mouse" icon. Navigate to the "Device Settings" tab and click on the Synaptics device in the list. If you have installed and use custom software other than a Synaptics application for controlling the touchpad, select it instead. Click the "Settings" button. Click the "+" symbol to expand the "Pointing" section in the left frame, and then the "Sensitivity" section. Click on "PalmCheck." If you have replaced the Synaptics drivers, the menu may use a different set of options. Click and drag the bar to the right, closer to the "Maximum" setting. An increased PalmCheck setting will help decrease cursor jumping due to accidental palm activations, a common occurrence when typing. Click on "Touch Sensitivity." Click and drag the bar to the right, closer to the "Heavy Touch" end. This will ensure light brushes by fingers or accidental activations by other objects will not cause the cursor to jump. Click "Apply" to test the settings, and "OK" when satisfied to save the changes and close the window.

Swap out the mouse.

If there is a ball underneath, remove it and clean the X and Y rollers.

You're probably managing to hit the touchpad below the keyboard with the heel of your hand, or you're brushing it with a finger. This can cause the cursor to jump. Many people find it convenient to turn off the touchpad when using a word processing application, and you may want to plug in a regular mouse.

Change your mouse

Does the cursor jump around when your hands are nowhere near the touchpad? The touchpads are heat and pressure sensitive. I personally have very warm (and sometimes sweaty) hands. I have this problem often when working on laptops. If I hover my hands over the pad, it causes the mouse to move. I've had to take a business card, put tape on one side of it, and use it as a flip-cover for the touchpad on most of my laptops. If the cursor moves around when you're nowhere near the laptop, then you may want to try disabling the pointing stick (if it has one). I've had several clients with laptops where the pointing stick mouse control go crazy and move and click on things.

Try this software:

Touch Freeze will disable the touchpad when you start typing. I have not used it, but give it a try.

Also, your touchpad could be wearing out or a driver reinstall could be in order. My wifes Toshiba had a bad touchpad and the cursor would jump all over the place. I disabled it and she now uses an external mouse. No problems anymore.
