Before you restart or shut down your computer, make sure to save all necessary work to prevent data loss.

3 Rule Out a Possible Hardware Issue

If Problems Continue

Keyboards have moving parts that can wear out over time, as well as simple electronics that can have problems.

At times, the shift or caps lock key may become stuck internally on the keyboard, or the simple control processor in the keyboard may start having problems, resulting in strange behavior including all-caps typing.

  • If available, connect a different keyboard and see if problems continue. If this solves the problem, the keyboard has failed and simply needs to be replaced.
  • If the keyboard is wireless, make sure it's charged fully, or replace the batteries.
  • As a last step the keyboard may need to be serviced or replaced.
