Hi @Abdallah10,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

I understand how frustrating this issue must be, especially when basic hardware like the touchpad isn't working after switching back to Windows 10 on your HP Laptop PC 15-dw4000 (4Z345AV).

1. Check for Windows 10-Compatible Drivers

While HP may not list Windows 10 drivers for this model directly, you can still try:

• Visiting the official driver page:
  👉 HP Laptop PC 15-dw4000 (4Z345AV) Software and Driver Downloads | HP® Support
• Try installing the Windows 11 touchpad driver in compatibility mode for Windows 10:
  • Right-click the installer > Properties > Compatibility tab > Choose Windows 10.

2. Run HP PC Hardware Diagnostics

You can test the touchpad hardware using HP's built-in diagnostics:

• Turn off the laptop.
• Turn it on and press Esc repeatedly, then press F2 for diagnostics.
• Go to Component Tests > Mouse/Touchpad and run the test.
