touchpad not working, no light, windows 10

[mkiefer]

I just installed windows 10 on my elitebook and I installed the recommended driver for the mouse/touchpad and the touchpad does not work.  I see there are many versions of it online.  Which one will work for my Elitebook 8470p in Windows 10?

I tried the HP assistant, I tried windows update.  I downloaded the driver that is suggested from the HP web site.  I  have tried a few other versions of the driver.  They all install fine and say the device is working fine, but it does not respond to the touch.  Exactly what version of the Synapse driver should I use for this model laptop for Win10?  I see other threads where they just used a different version and it worked for them.

@mkiefer Welcome to HP Community!

I understand that touchpad is not working.

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
