Left Click not working while holding keyboard keys

Hi Cennac Duding,

Just to add on to the points already mentioned by Q&A Assist, here are a couple of things you can double‑check:

1. Reinstall the correct HP touchpad driver

Since you mentioned switching to HID‑compliant or PS/2 drivers, these generic drivers usually only provide basic functionality and can remove the settings needed to adjust touchpad behavior.

I’d recommend going to the HP support site for your specific model and reinstalling the original touchpad driver. This often restores the full set of touchpad options and resolves this type of issue.

2. Quick check to narrow it down

• Try using an external USB mouse while holding a key
• If it works normally, that helps confirm the keyboard is working fine and the issue is related to the built‑in touchpad settings rather than hardware

If you’re not sure where to get the right driver, feel free to share your HP model and I can help point you to the correct one.

The behavior is typically caused by how Windows handles input from the built‑in keyboard and touchpad, not by the mouse driver type. After a reset, touchpad/keyboard settings often revert to defaults, which can block clicks while keys are held (a palm‑rejection or “disable while typing” feature).

Use these steps to troubleshoot and adjust:

1. Check basic hardware behavior

• Make sure the issue is only with the built‑in touchpad + keyboard.
• Connect a USB mouse and test: if left‑click works while holding keys on the external mouse, the hardware is fine and the issue is configuration/driver for the built‑in devices.

2. Verify device and driver health

• Unplug any external USB devices and wait a few seconds so Windows unloads their drivers, then plug them back in if needed.
• Try different USB ports if using an external mouse.
• Ensure there is no dirt or debris on the touchpad or keyboard that could be interpreted as extra input.

3. Update mouse/touchpad and keyboard drivers

• Use Windows Update to pull the correct drivers after the reset:
  1. In the search box on the taskbar, type check for updates, then select Check for updates.
  2. Under Windows Update, select Check for updates and install any offered driver or firmware updates.
• If needed, update manually via Device Manager:
  1. In the search box, type device manager, then select Device Manager.
  2. Expand Mice and other pointing devices and Keyboards.
  3. For each relevant device, double‑click it, go to the Driver tab, and select Update Driver, then follow the prompts.

4. Test with another PC if possible

• If an external mouse or keyboard shows similar issues on another PC, the device may be faulty and need replacement.

5. If the problem persists only on this Windows install

• Since the issue started immediately after a reset, and if driver updates do not help, perform another reset using Settings → System → Recovery → Reset this PC, choosing Keep my files to reinstall Windows while preserving personal data. This can repair mis‑applied drivers or settings from the previous reset.

If none of the above changes behavior and only the built‑in touchpad fails to click while keys are held, contact the laptop manufacturer for touchpad‑specific driver/software and configuration guidance.
