I reviewed your post and I understand that the cursor moves erratically when you connect the charger.


Don’t worry, I assure you I will try my best to get this sorted.


Have you tried a different power outlet?


Meanwhile, I recommend you update the from the below link and check whether the issue is resolved.


BIOS: https://ftp.hp.com/pub/softpaq/sp111501-112000/sp111516.exe


If you continue facing the issue, then uninstall the touchpad driver from the device manager and then download and install it from the below link.




Let me know how it goes and you have a great day!

@Huzaifa-123Welcome to the HP Support Community!


As this is a hardware issue, I'd suggest you contact HP in your region regarding the service options for your computer. 


If you are having trouble navigating through the above options, it's most likely because the device is out of warranty. If yes? please send me a private message with the region you are contacting us from. Check next to your profile name, you should see a little blue envelope, please click on it.   


Have a great day!
