Re: Dell n4050 touchpad and ac adopter problem

Hi Mubashir Iqbal,

Please share the operating system installed.

You may connect your computer to a different walljack and see if it makes any difference. Another step you may try is to uninstall and re-install the touchpad driver from 'Device Manager' by following the steps below:

  • Click on “Start” and right click on “Computer”.
  • Click on “Manage”.
  • Click on “Device Manager”.
  • Under “Mouse and other pointing devices”, you will find the touchpad driver listed.
  • Right click on it and click on “uninstall”. 
  • Check the box to delete the software.
  • Restart your system 
  • Download and install the drivers from link: http://dell.to/WA4qNp
  • Check if the issue is resolved or not. 

If the issue persists, you may update system BIOS. 

Note: Make sure the ac adapter is connected and the battery is charged 10% or above to update the BIOS. Also, disconnect all the external peripherals before updating the BIOS. All the programs should be closed and documents saved.

Hope it helps.

Thanks and regards,
