Something you must do if your laptop touchscreen stops working

Alright — when a laptop’s touchscreen stops working a few minutes after booting, it usually points to a driver or power management issue rather than a hardware fault. Let’s go step-by-step to fix it

Step 1: Check if the touchscreen is still detected

1. Press Windows + X → Device Manager.
2. Expand Human Interface Devices.
3. Look for HID-compliant touch screen.
   • If it’s missing, click Action → Scan for hardware changes.
   • If it’s there but greyed out, right-click it → Enable device.

Step 2: Reinstall the touchscreen driver

1. In Device Manager, right-click HID-compliant touch screen → Uninstall device.
2. Restart your laptop — Windows will reinstall it automatically.
3. Test the touchscreen after reboot and observe if it stops again.

Step 3: Disable power-saving on the driver

Sometimes Windows turns off the device to save power.

1. Still in Device Manager, right-click HID-compliant touch screen → Properties.
2. Go to Power Management tab.
3. Uncheck Allow the computer to turn off this device to save power.
4. Restart and test again.

Step 4: Update drivers

• Go to your laptop manufacturer’s support page (HP, Dell, Lenovo, etc.).
• Download and install the latest chipset and touchscreen / display drivers.
• Also check Windows Update → Optional updates → Driver updates.

Step 5: Test in Safe Mode

Boot into Safe Mode:

1. Hold Shift while clicking Restart → Troubleshoot → Advanced Options → Startup Settings → Restart → Press 4 for Safe Mode.
2. Test the touchscreen.
   • ✅ If it works fine in Safe Mode → a background app or driver is conflicting.
   • ❌ If it still fails → hardware or firmware issue.

Step 6: Calibrate or reset the touchscreen

1. Go to Control Panel → Hardware and Sound → Tablet PC Settings.
2. Click Calibrate → follow the steps.
3. If no change, open Settings → System → Display → Advanced display settings → Display adapter properties → check for any touchscreen options.

Step 7: BIOS/UEFI update

If the touchscreen keeps failing after a few minutes even after Windows reinstall, check your manufacturer’s site for a BIOS update — it often fixes hardware communication issues.

Step 8: Hardware test

If you’re using an HP or Dell laptop, run the built-in diagnostics:

• HP: Turn off → press Esc → then F2 for System Diagnostics → run Touchscreen test.
• Dell: Power on and press F12 → Diagnostics.

If it fails the test → touchscreen hardware or digitizer cable might be loose or faulty.
