Touchpad issue

It used to work but currently not working

Hello Cgoad,

There are a couple of steps I would suggest which would help us in isolating the issue further.

Disable the touch-pad and check if it works in safe mode.
-- Restart the computer. Keep tapping F8 on the Dell Logo Screen. Once the computer enters Advanced Boot Option, select Safe Mode. Press Enter. Check if the touch-pad is working even though it is disabled.

I also would suggest Re-installing the Quickset drivers.
-- Uninstall the existing quickset drivers from program and features.
-- Restart the computer.
-- To download the quick-set, click here to get to the drivers and download page.
-- Enter the System Service Tag.
-- Click Drivers and Download Tab.
-- Choose the Operating System.
-- Download and Install the Quick-set for the system.
-- Restart the computer and check the functionality. 

Please try the steps and write back with results, would be glad to assist you further. I would also request you to mention the system model.

Awaiting your response! 

I tried the suggestions and it didn't work? I am not sure what to do... when I hit FN+F3 the touch pad shoudl lock but it doesn't the light above the touch pad comes on but when you touch the pad it still moves the cursor around. I clicked on your link and thought I downloaded the correct driver but not sure if it was the correct one... do you have anymore suggestions.

one more thing... I tested the other hot key functions and they work just not the one to lock the touch pad.

thanks for all your help!
