If your computer have a, Synaptics Touchpad you can try these steps:

Open the "Mice and Other Pointing Devices" selection.

2. Click on the "Device Settings" tab of the "Mouse Properties" window. The "Device Settings" tab is at the top of the window and located farthest to the right

3. Highlight the Synaptics Touchpad from the list of available pointing devices. Click the "Disable" button underneath the list. Click "OK" on the pop-up menu to confirm your selection. Click "OK" on the Mouse Properties window to close the window. Your Synaptics Touchpad will now be disabled.

Make sure to connect a USB mouse to your laptop before disabling the touchpad so that you will still have control of your pointer.

Hope this help. Goodluck!

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.

Hello,
Windows hides rarely used icons. If your does, then the task bar shows a left pointing arrow < . Click it and look for the icone for touchpad.

If you cant find that icon,
In WINDOWS XP
1. Start
2. Contol Panel
3. Right click the Mouse icon.
4. Under the Touchpad ON/OFF thumbnail, put a check mark in the disable option.
5. Use the same procedure to enable touchpad

probably need a driver or at least an updated driver.

Also go into the control panel and see if there is an icon for the touchpad... double-click on that icon and look for settings to enable the scroll pad.
