HP Spectre X360 touchpad fails

[maxomini]

Touchpad not working when tested in BIOS, and hence not 
discovered by windows.

Purchased a new one,  replaced it but the problem
not solved.

Any ideas?

Is the problem in the motherboard?

Hi @maxomini,

Welcome to the HP Support Community.
 

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

You’ve done some solid troubleshooting already. Replacing the touchpad rules out the physical component, so the issue likely lies elsewhere. Here’s what we know:

• Touchpad not detected in BIOS → This means the system firmware isn’t seeing the device at all, which usually points to: 
  • Motherboard issue (touchpad connector or embedded controller failure)
  • Firmware/BIOS corruption
  • Cable or connector damage (even a slight misalignment can cause this)

Steps to Narrow It Down:

1. Check the Touchpad Ribbon Cable & Connector
   • Ensure the cable is seated properly and not damaged.
   • Inspect the connector on the motherboard for bent pins or debris.
      
2. Update or Reflash BIOS
   • Download the latest BIOS for your Spectre X360 from Official HP® Support.
   • Reflash it even if you’re on the latest version; corruption can cause detection failures.
      
3. Perform an Embedded Controller Reset
   • Disconnect AC power and battery.
   • Hold the power button for 15 seconds.
   • Reconnect and boot.
      
4. Run HP UEFI Hardware Diagnostics
   • Boot into HP Diagnostics (press Esc → F2 at startup).
   • Check if the touchpad is listed under input devices.

If Still Not Detected:

Yes, it’s very likely a motherboard issue. Specifically, the touchpad interface circuit or EC (Embedded Controller). Unfortunately, replacing the touchpad won’t help if the board isn’t communicating with it.
