As you type, your wrists could be close-enough to the touch-pad to move the mouse-pointer.

Click Start
Click Control Panel
Click Mouse
Change the setting to disable the touch-pad.

Customizing the Touch Pad

You can use the Mouse Properties window to disable the touch pad or adjust
the touch pad settings.
1 Click Start , and then click Control Panel.
2 Click Hardware and Sound.
3 Click Keyboard.
4 In the Mouse Properties window:
• Click the Device Select tab to disable the touch pad.
• Click the Touch Pad tab to adjust touch pad settings.
5 Click OK to save the settings and close the window.

To turn off the touchpad when an external mouse or other pointing device is present, you can goto the Control Panel and double click the Mouse properties icon.

Click the Device Select tab and check "Disable Touch Pad when USB Pointing Device is present." The cursor will no longer move via the touchpad.

Alternatively, you can permanently disable the touchpad of your laptop by clicking the "Disable Device" in the Touch Pad setting. Advanced users can disable the touchpad from the BIOS setup [press F2 when the computer is booting to enter BIOS settings]

Unfortunately, there are no keyboard shortcuts to enable/disable Touchpad movement or tapping. You can however drag the Mouse icon from the control panel to your Quick launch bar for quick access.

If that sounds too much effort, you may consider adjusting the sensitivity of the touchpad. This can be accessed from the Touch Pad tab of our mouse properties. Choose a low setting.

You could try adjust the touchpad settings. Sometimes there is a touchpad icon in the taskbar that you can right click on to adjust the properties. You can also disable the pad and use a USB mouse instead.

Your palm might be brushing on the touch pad while you are typing that is probably why the cursor jumps to a different location. as for disabling the touch pad I think that it is not possible unless you install a synaptics driver for your laptops touch pad.

Pressing F6 on your laptop will disable the touch pad or one of the F keys that has a picture of a finger.
