Hola, la única solución que he encontrado en sony, viene en inglés, espero que te ayude:

"The special buttons, function keys or Hot keys on the computer or keyboard do not operate properly.

Follow this procedure to enable the special buttons, function keys or Hot keys on the computer or keyboard in the Microsoft® Windows® XP operating system.

IMPORTANT: On AMD™ or Transmeta™ processor-based computers, the function keys are hardware controlled and not controlled by a hot-key utility.

NOTES:

* Third-party keyboard or mouse software may affect the performance of the function or Hot keys.
* The volume button and brightness key on some computers will not work if the VAIO Event Services Manager application is not running.
* The Magnify button and the Fn keys will not function properly before the operating system has finished starting.
* The setting may not be saved if the ESC key is used to close the Fn display. Press the ENTER key or allow the Fn display to close automatically to save the setting.

1. Click the Start button, then click Run.
2. In the Run window, next to Open, type MSCONFIG.
3. Press the ENTER key.
4. In the System Configuration Utility window, click the Services tab.
5. On the Service tab, under Service, ensure that there is a check in the VAIO Event Services Manager checkbox.

* On some models, the Sony Notebook Utilities includes the VAIO Event Service application and the Sony Utilities DLL.
* When reinstalling the VAIO Event Services Manager you may have the option to repair.
* If the VAIO Event Services Manager is checked, ensure the service is set to start automatically.
