Built‑in Keyboard and Touchpad Not Responding or Fn Keys

Keyboard and touchpad issues may stem from software settings, drivers, or hardware faults. This article offers an ordered approach to restore input functions.

Step-by-Step Fixes

  • Restart and test: Reboot the system and test in BIOS to determine if the issue is software-related.
  • Function (Fn) lock: Some models have an Fn lock. Toggle it (often Fn+Esc or a dedicated key) to restore expected key behavior.
  • Drivers and ATK package: Update keyboard, touchpad, and hotkey (ATK or ATKACPI) drivers from the official support site.
  • Touchpad settings: In Windows Settings > Bluetooth & devices > Touchpad, make sure it’s enabled and sensitivity is correct.
  • External device test: Connect a USB keyboard/mouse; if those work, the issue likely is internal and may need service.

If keys are physically damaged, sticky, or unresponsive at BIOS level, contact authorized service for repair or replacement. Keep proof of purchase and system details for support.
