Why is my laptop keyboard typing on its own?

Answer

A laptop keyboard typing by itself is usually caused by a hardware or software issue. Common causes include stuck or damaged keys, dust or liquid spills affecting the keyboard, or a faulty keyboard membrane. It can also be caused by software problems such as driver errors, malware, or accessibility settings like “Sticky Keys” being enabled. In some cases, an external keyboard connected to the laptop may also be sending repeated inputs. Cleaning the keyboard, restarting the laptop, checking settings, and updating or replacing the keyboard can help resolve the issue.
