My touch pad mouse isn't working

[topcatto]

My notebook has been hanging up a lot lately and has occasionally rebooted itself.  This morning the touch pad mouse is not working at all - I have run the HP PC Hardware Diagnostics Window 3.1.0.0 and everything shows as PASSED.  Any suggestions of what I can do to try to diagnose and fix the mouse problem as well as the hanging up issues?  Would appreciate any help - thank you

Hi  @topcatto,
 
Welcome to the HP Support Community!

Thanks for reaching out!

I understand how it must be to deal with both the touchpad not working and your notebook hanging or rebooting unexpectedly. Thank you for already running the HP PC Hardware Diagnostics   that’s a great first step. 
To help you further, I’ll need the exact HP notebook model you’re using ?

In the meantime, here are  few steps you can try :

1.Check Touchpad Enable Settings

Sometimes the touchpad gets disabled through settings or a shortcut key.

Press Fn + F5/F6/F9 (varies by model) or go to Settings → Devices → Touchpad

Ensure the touchpad toggle is set to On

If your notebook has a small LED on the touchpad, double-tap it to enable

2.Update or Reinstall Touchpad Driver

Driver issues can cause the touchpad to stop responding.

Open Device Manager → Mice and other pointing devices

Right-click your touchpad driver (e.g., Synaptics, ELAN)

Select Update driver → choose Search automatically

If no update is found, select Uninstall device, then restart your notebook to reinstall

3.Run Windows Updates

Pending updates can cause instability and hardware issues.

Go to Settings → Update & Security → Windows Update

Click Check for updates

Install all critical and optional updates

Restart your notebook after updates

4.Check for Overheating or Resource Usage

Frequent hangs and reboots may be linked to overheating or high CPU usage.

Press Ctrl + Shift + Esc → Task Manager

Monitor CPU and memory usage

End tasks consuming excessive resources

Ensure vents are clear and notebook is on a hard surface

5.Perform HP System BIOS Update

A BIOS update can resolve hardware compatibility issues.

Visit HP Support https://support.hp.com/  → Drivers & Downloads → Enter your notebook model

Download the latest BIOS update

Follow on-screen instructions carefully

Ensure notebook is plugged in during update

These steps should help narrow down whether the issue is software-related or hardware-related. 

I hope this helps.

Thank you for your detailed reply.  Sorry for my delay in replying but I was traveling quite a bit.  

So the latest situation is that I found mention of the Touchpad in the Hidden list, and I was able to completely remove it, but my problem now is that I cannot find the correct driver to re-install it.  When I go to the HP support page for drivers etc, and it asks for my OS system, it ONLY gives me the option for Windows 10 and I am running Windows 11.  I even reached out the device manufacturers and they also told me to contact HP!  So I'm going around in circles.  Is there any way you could possibly provide me a direct link for the Synaptics Touchpad driver for Windows 11, 64 bit for HP Notebook - 15t-da000 CTO, Product 3FR23AV, Serial # CND8291 MMY - I would most certainly appreciate it.

I found out that my harddrive was pretty full, so I spent quite a bit of time cleaning out old files etc and now that it's less full, the PC seems to be running somewhat better.  So, if I could get the Touchpad fixed, I think I'll be in pretty good shape!  Thanks, and hoping to hear back from you soon!
