Keyboard troubleshooting

Context

There are two possible failure modes in the keyboard:

•

One or more keys are stuck, so that the key does not react when a keydome or a side key is pressed. This

kind of failure is caused by mechanical reasons (dirt, rust, mechanical damage, etc.).

•

Malfunction of several keys at the same time. This happens when one or more rows or columns in the key

matrix are failing (shortcut or open connection).

If the failure mode is not clear, start with the Keyboard test in Phoenix.
