Hello abhishektomer691,

I am from Dell Social Media and Community.

Check your power settings from control panel and verify if there is any option related to touchpad changes when the AC Adapter is connected. (Which usually is not the case)

Log on to www.support.dell.com and download the latest drivers to update it.

If you need any further assistance, feel free to message me on Twitter. I will be happy to assist and Happy Holidays to you and your family.

Actually need to uninstall software or drivers if you downloaded from dell.com website. it will work fine with default OS Drivers.

I am using the same laptop and I used to face the same problem as yours. But then I recognized that when you put your laptop for charging in the wall socket then it hangs because of some voltage fault. Try to connect your charger with the external cord connected to a wall socket. It will run smoothly. Because the input voltage required is 19.5v.
