Use this guide to replace a broken or non‑responsive touchpad (aka trackpad) on your HP EliteBook 845 G9 laptop.
You may need to replace the touchpad if it's behaving erratically, unresponsive to touch inputs, or inconsistent in cursor movement.
When handling batteries, don’t use sharp or metal tools, and don’t bend them or use excessive force. If your battery is swollen, take appropriate precautions.
