Touchpad not working

[POTHOS1]

The touchpad on my laptop is not working.  There is no cursor, and nothing can be selected using the touchpad.  I tried using previous suggestions to update drivers, but the touchpad does not show up on the list of devices.  I plugged in an external mouse and that works, but no touchpad.  Also, unrelated (maybe?) but the fan runs constantly when the laptop is plugged in and was running while it was sleeping when I went to use it this morning and discovered the touchpad not working.

@POTHOS1 Welcome to HP Community!

I understand that you are facing issues with the touchpad.

Do not worry. I will try to fix the issue.

First, restart the computer and tap on F10 during restart, once on BIOS screen, move the mouse cursor around to check if it works normally, 

If it does, it would confirm a software issue and you follow the below steps if it doesn't work on its a hardware failure and I would suggest a touchpad replacement. 

 
I recommend you to uninstall any generic synaptic drivers showing up for the touchpad (if available) under hidden devices from the device manager: 

• Click Start, point to All Programs, point to Accessories, and then click Command Prompt. 

• At a command prompt, type the following command , and then press ENTER: 

set devmgr_show_nonpresent_devices=1 

• Type the following command a command prompt, and then press ENTER: 

start devmgmt.msc 

• Troubleshoot the devices and drivers in Device Manager. 
  NOTE: Click Show hidden devices on the View menu in Device Manager before you can see devices that are not connected to the computer. 

• When you finish troubleshooting, close Device Manager. 

• Type exit at the command prompt. 
   
  Note that when you close the command prompt window, Window clears the devmgr_show_nonpresent_devices=1 variable that you set in step 2 and prevents ghosted devices from being displayed when you click Show hidden devices. 

And then download a new version of the synaptic drivers using this link: Click here
