Laptop computers contain a touch pad that is used to move a cursor around onscreen, rather than an external mouse like desktop computers. There are various reasons why a laptop touch pad may not be functioning correctly. Several troubleshooting techniques are available that you can try to restore your touch pad to working condition.

Reboot the laptop computer. Sometimes this alone can fix the problem. If the touch pad is still not working, proceed to the following steps.
Disconnect any external peripheral devices such as a keyboard, printer or other USB devices. Reboot the computer once again. If the touch pad works after you removed all external peripheral devices, reconnect each device to the laptop one at a time to figure out which one is interfering. Replace the problem device if necessary.
Connect an external mouse that you have verified is in working condition. Check if the problem exists. If it does, proceed.
Verify that the touch pad is not disabled. Press the "FN" and "F9" keys simultaneously. This will enable the touch pad if it was disabled and should turn it back on.
Click on the "Start" menu in the lower left corner of the screen and go to "Control Panel." Double-click the "Mouse" icon and click the "Device Settings" tab. Click the "Enable" tab if it is not already selected. This is another option to enable the mouse if using the "FN" and "F9" keys does not work.
Disconnect the mouse from the "Device Manager" in the "System Properties" tab if the above steps did not work. Reinstall the latest driver available. Go to the Toshiba website to download the newest driver available for the touch pad.
Touch pad is Not Working
Reboot the laptop computer to see if this fixes the problem.
Detach any external devices such as a mouse, keyboard, printer or any USB devices and reboot the laptop computer. Check if the problem still persists with the cursor. If not, one of the external peripherals most likely caused the problem. Reattach each peripheral device one at a time to determine which one caused the problem. Replace the faulty device.
Connect an external mouse if you have not already and check if the problem persists. If it does, then move on.
Wait until all programs are loaded during heavy system load, which could cause the cursor to seem erratic. Try to move the cursor after all the programs are finished.
Click on "Control Panel" under the "Start" menu in the lower left corner of the screen. Go to "Mouse Pad Settings" and click on "Calibrate" underneath it. Sometimes calibrating the touch pad can resolve the issue of an erratic cursor. Avoid moving the cursor during the recalibration period. If this does not resolve the problem, there is most likely a hardware problem.
