Touchpad erratic which part no

[tarmiricmi]

Hi my touchpad is erratic, it lags, jumps the cursor randomly, that was bearable and could be resolved by either restart or reset the Synaptics device. As of today it is not possible to fix it.

I haven't tried booting into something other than Windows, but I tried multiple drivers, clearing them etc but no effect.

So the issue is most probably hardware one.

Can someone say what the part number the touchpad for my laptop is?

@tarmiricmi, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

It sounds frustrating that your touchpad is misbehaving! If the issue persists despite trying different drivers and resets, you're likely dealing with a hardware-related issue. 

However, before you jump to conclusions, here are some troubleshooting steps you can try to rule out any software or system-related causes:

Test in BIOS/UEFI Mode

• Testing in BIOS or UEFI will help confirm whether the issue is hardware-related or software/driver-related.
  • Restart your laptop and press the BIOS/UEFI access key (usually F2, F10, Esc, or Del, depending on the manufacturer).
  • In the BIOS menu, see if you can navigate using the touchpad.
  • If the touchpad works fine here, it’s likely a software/driver issue. If it’s still erratic, it’s most likely hardware.

Check for Physical Obstructions/Debris

• Dust or dirt can cause erratic behavior in touchpads.
  • Gently clean the surface of the touchpad with a soft, lint-free cloth.
  • Use compressed air to blow out any dust around the edges of the touchpad.
  • Check if the issue persists.

Disable "Touchpad" in Device Manager (and test with a mouse)

• If there’s a conflict between your touchpad and another device (such as a mouse), this could cause issues.
  • Press Win + X and select Device Manager.
  • Under Mice and other pointing devices, find your touchpad (often listed as "Synaptics," "ELAN," or "Windows Precision" depending on the brand).
  • Right-click and Disable the device.
  • Use an external mouse to see if the issue persists with the touchpad disabled.

Reinstall Synaptics/Touchpad Driver

• You mentioned trying different drivers but reinstalling them can sometimes clear issues.
  • Go to Device Manager > Mice and other pointing devices.
  • Right-click your touchpad device and select Uninstall.
  • Restart your computer. Windows should reinstall the driver automatically.
  • If that doesn’t fix it, visit HP Support website and download the latest driver directly from there

Test in Safe Mode

• Booting in Safe Mode can help determine if the problem is caused by third-party software.
  • Hold down the Shift key and select Restart from the Start menu or lock screen.
  • After the computer restarts, navigate to Troubleshoot > Advanced options > Startup Settings.
  • Click Restart, then choose Safe Mode from the list.
  • Test the touchpad in Safe Mode. If it works fine in Safe Mode, it's likely caused by a third-party application or software conflict.

Check the Touchpad Settings (Sensitivity/Features)

• Sometimes, the touchpad sensitivity or gestures settings can cause issues.
  • Open Control Panel > Mouse (or Settings > Devices > Touchpad).
  • Adjust the touchpad sensitivity settings and disable any complex gestures to test if this improves performance.
  • If you're using Synaptics drivers, you may also have a Synaptics Touchpad Settings app in the system tray. You can adjust settings there too.

Check for Windows Updates

• Sometimes, Windows updates include fixes for touchpad drivers or system-related bugs.
  • Go to Settings > Update & Security and check for updates.
  • Install any available updates and restart your system.

Test an External Mouse

• If the external mouse works fine, it's a good indicator that the issue lies within the touchpad itself.
  • Simply connect a USB or wireless mouse and use it to navigate the system.
  • If the mouse works normally and the touchpad still has issues, the touchpad hardware might be faulty.

Check Power Settings

• Power-saving settings can sometimes affect device performance.
  • Go to Device Manager > Mice and other pointing devices, right-click the touchpad, and choose Properties.
  • Go to the Power Management tab and uncheck the box that says "Allow the computer to turn off this device to save power."
  • Click OK and test again.

I hope these steps help resolve the issue
