1. touchpad not working properly. 2.function key does not work for volume n brightness

HP Notebook - 15-ac121dx
Microsoft Windows 10 (64-bit)

1. when i start my laptop, touchpad works fine but after a while it starts missbehaving. right click n left click work fine but cursor is out of control.i have checked if its driver is not updated but it is updated.i uninstalled its driver n installed it back but even then it is not working. i read somehwere if its touch screen is turned off then touchpad works fine but even if i turn touch screen off it does not work.

2.i dont know about other function keys but i use function keys for brightness and volume all the time. i dont know if it was last window update or what else went wrong that these function keys are not helping anymore. These keys still make a pop up sound which means keyboard buttons are working fine.

please help.

Hi @sohaibaraien,

I have read your post and wanted to help. I understand that touchpad and keyboard do not work well.

 

Below is a document may help to troubleshoot the touchpad problem:

For the Fn key issue, reinstall the HP System Event Utility
