Hi @TJ8799 

Welcome to the HP Support Community! We're here to help you get back up and running.

I’m sorry to hear that the touchscreen stopped responding after you replaced the keyboard. You’ve already done a careful job reassembling the device, so let’s go step by step to bring the touchscreen back to life.

 

Step 1: Check hardware connections

Since the touchscreen relies on a separate cable connection to the system board, it’s possible that during the keyboard replacement the touchscreen cable was loosened or not fully seated.

• Power off the computer completely.
• Disconnect the AC adapter and remove the battery if possible.
• Reopen the unit carefully and check that the touchscreen/digitizer cable is firmly connected to the motherboard.

 

Step 2: Verify in Device Manager

• Press Windows key + X and select Device Manager.
• Expand “Human Interface Devices.”
• Look for “HID-compliant touch screen.”
• If it’s missing, the system isn’t detecting the hardware, which usually points to a connection issue or driver problem.

 

Step 3: Run Windows updates

• Go to Settings > Update & Security > Windows Update.
• Install all available updates, including optional driver updates.
  This ensures the touchscreen driver is refreshed.

 

Step 4: Use HP Hardware Diagnostics

HP provides a tool to test hardware functionality:

• Restart the computer and press F2 repeatedly to open HP PC Hardware Diagnostics UEFI.
• Select “Component Tests” > “Touchscreen Test.”
• Follow the on-screen instructions to check if the touchscreen responds.

Here’s a direct guide from HP on using the diagnostics tool:

Step 5: Calibrate or reset the touchscreen

• Open Control Panel > Hardware and Sound > Tablet PC Settings.
• Under “Display,” select “Calibrate the screen for pen or touch input.”
• If calibration isn’t available, it means Windows isn’t detecting the touchscreen, again pointing back to the hardware connection.

The fact that the touchscreen disappeared from Device Manager strongly suggests the cable connection was disturbed during the keyboard replacement. Once the cable is reseated securely, the touchscreen should reappear and function normally.
