a Bluetooth keyboard is paired but not working correctly
If the live test passes, the investigation can usually move away from total hardware failure and toward the affected app, permissions, routing or configuration.
Try the simple causes first
- 1
Run the relevant DeviceOK keyboard test and note which exact keys/events fail.
- 2
Reconnect the keyboard or verify wireless power/connection.
- 3
Check whether the key works in another app or browser.
Work through the problem in order
- 1
Run the relevant DeviceOK keyboard test and note which exact keys/events fail.
- 2
Reconnect the keyboard or verify wireless power/connection.
- 3
Check whether the key works in another app or browser.
- 4
Verify the active keyboard language/layout and any Num Lock/Fn/keyboard-mode settings.
- 5
Restart the affected app before changing drivers or firmware.
- 6
If the same key fails consistently across tests, consult the keyboard/laptop manufacturer's official support path.
If the keyboard passes the DeviceOK test, prioritize the affected application, permissions, routing, or configuration before assuming the hardware is dead.
If the keyboard also fails in DeviceOK and another trusted app, broaden the diagnosis to connection, OS settings, drivers/firmware, and then possible hardware failure.
