Mouse pad /touch pad/track pad not working

Hello All,

Recently I have replaced the battery and all working good except the touchpad. If I connect the external mouse then can see the mouse otherwise there is no mouse pointer and I am unable to do anything with the internal trackpad.

Thank you for posting on the HP Support Community.

I have a few troubleshooting steps we could try to fix the issue:  
Step: 1 BIOS Defaults -
1) Shutdown the computer. 
2) Turn the computer back on again and repeatedly tap on the ESC until a Startup menu appears. 
3) Press F10 once for BIOS. 
4) Press F9 for BIOS defaults. 
5) Press F10 to save and exit. 

Step: 2 Re-install the touchpad driver -
1) Right click on the start or Windows icon and open the "Device Manager".
2) Expand the "Mice and other pointing devices".
3) Right, click on the "Synaptics TouchPad".
4) Click on uninstall and restart the computer, this should fix the issue.

Hope this helps! Keep me posted for further assistance.
