RE: DELL VOSTRO 2520 TOUCHPAD PROBLEM

Hi ak_singh,

Please Enable the Touchpad in Touchpad properties, connect an external mouse to computer and follow the below mentioned steps:

  1. Go to Control Panel and select Mouse. The Mouse properties window is displayed.
  2. Open the Touchpad tab and then select Click to Change Touchpad Settings.
  3. Click Enable to change the settings.
  4. Disconnect the Mouse and check if the touchpad is working.

To confirm the hardware functionality, I would request you to run the Pre-Boot System Assessment (PSA / ePSA) Diagnostics 

You may also refer to this video on how to run the ePSA Diagnostics: http://dell.to/1dMViiD

Please check and post the results.

Thanks & Regards,
Nikhil D
