Disable Touch Pad on HP Laptop running Windows 10.

This guy has the same problem as you and HP forum staff point him to :

Whether you are talking to a live person on the phone or getting someone from email, just make sure that the HP front line person understand that the "old" solutions won't EVER work and he needs to direct you to someone who understand DCH drivers.

If you are not sure how to say it in person on the phone, then it may be easier for you to just copy and paste what I wrote in the 2 threads here and send it to HP by email.

I never had to deal with the actual tech support hotlines before (so I can't give you any advice) but last year I was able to piggyback on manufacturer's front line forum staff and they sent my messages directly to the appropriate people. This is why I suggested to you to find a HP discussion where some HP staff managed to fix an intel or nvidia or realtek "DCH driver/app" installation problem --- and then piggyback on it. The touchpad app problem is new and nobody has any clue on it, but the realtek app problems have been around for 18 months.

If you search on HP's forum the last few days, there are several threads on this.

So if you want to get attention fast, then START a discussion on HP's forum --- just copy and paste all my writing with all the screenshots --- and then link all the similar HP threads that have started in the last month of so,  and demand the front line staff to direct you to somebody who knows what's going on (and not some vague HP support hotline).

Have you tried the setting in the 'Touchpad' tab by clicking Settings > Devices > Touchpad, Additional settings? (Or maybe available in Settings > Devices > Mouse, Additional Mouseoptions?)

Then put a checkmark in the box with 'Disable internal pointing device when external USB pointing device is attached' in the 'Touchpad' tab and click Apply, OK.

(And if you meant that the Touchpad can be really disabled always by pressing the Disable button.)

Thanks for replying. Yes I have tried all those steps numerous times.

My TouchPad setting doesn't look like what you show.

When I click on Additional Settings I get the mouse properties 

Sorry to read that the needed solution wasn't that simple answer to the question for you.

Always keep in mind that you have a HP Laptop with the Synaptics for that HP Laptop preferably.

(The text says Precision may work but isn't neccesarily intended. And Thinkpad may be Lenovo Thinkpad intended.)

Consider installing the HP Support Assistant software too from the HP Support site to update your device (later).

Maybe you can tell us more about your specific HP Laptop and provide a picture of what you see in Device Manager exactly after you clicked View and selected Show hidden devices in the Menu first. You can take a picture by pressing Windows logo key + PrtScrn. (This is saved in Pictures > Screenshots.)

(You should probably Uninstall any TouchPad devices and update later.)

Have you retried the suggestion?

I'm back!

I uninstalled the driver update app and rolled back the touchpad driver to a previous version. Once I re-start, the current version gets reinstalled again. So I think I am back to square 1.

I haven't been successful in installing the precision touchpad driver after that.

The HP Support Assistant software analyses your system and can find and install the correct update for your device (later).

For now a small Registry hack may also help with disabling (if not correcting the other driver/software problem) if the other solution doesn't help yet and you feel secure in using the Registry directly.

First open Registry editor (type RegEdit.exe in Search) and go to HKEY_CURRENT_USER\Software\Synaptics, HKEY_LOCAL_MACHINE\Software\Synaptics and HKEY_LOCAL_MACHINE\Software\InstalledOptions\Synaptics, Right-click 'Synaptics' and choose Export to create a backup file with the current settings (3x).

Put this in a text file:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPCpl]

"ShowResetButton"=dword:00000001

"RestoreAllDefaults"=dword:00000000

[HKEY_LOCAL_MACHINE\Software\Synaptics\SynTPEnh]

"DisableIntPDFeature"=dword:00000022

"TrayIcon"=dword:00000011

[HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTP\Configurable]

"DisableTouchPadIfMousePresent"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTP\Defaults]

"DisableTouchPadIfMousePresent"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTP\Install]

"DeleteUserSettingsOnUpgrade"=dword:00000000

[HKEY_CURRENT_USER\Software\Synaptics\SynTP]

"DisableTouchPadIfMousePresent"=dword:00000001

[HKEY_CURRENT_USER\Software\Synaptics\SynTPEnh]

"DisableIntPDFeature"=dword:00000022

"TrayIcon"=dword:00000011

Rename the text file to TouchPadHack.reg, Right-click and choose Merge. Restart your Laptop (or Sign out maybe) to see if this works for you now.

(Maybe more details later.)
