PC computers have keyboard options that can be turned on without the user’s knowledge. Nothing can be more frustrating than beginning a session of work at your computer and finding that your keyboard is either responding very sluggishly or is not responding at all. The term locked keyboard can also be used when a keyboard is responding only sluggishly. Because there are system processes running in the background, keystrokes can take seconds to be recognized. These system processes can be turned on accidentally with errant keystrokes. Learning how to unlock your computer keyboard can save you hours of frustration.
