Non-Responsive Keys: If certain keys on the keyboard are unresponsive or do not register when pressed, it could be due to dirt, debris, or a faulty connection. Cleaning the keyboard or checking and reseating the keyboard cable may resolve the issue.
Sticky or Stuck Keys: When keys feel sticky or get stuck when pressed, it is often caused by spilled liquids or debris lodged beneath the keys. Cleaning the affected keys and the surrounding area can improve functionality.
