Applicable to: World-Wide
Keyboard/Auxiliary Input Device Checkout
Disconnect the external keyboard and mouse, then try the internal keyboard. If the internal keyboard works correctly, replace the external keyboard or mouse.
If the internal keyboard does not work correctly or an unexpected character appears, make sure that the three flexible cables extending from the keyboard are correctly seated in the connectors on the keyboard card. If the keyboard cables are seated correctly, run the Keyboard Test using the IBM ThinkPad 365 Advanced Diagnostics Diskette.
