Notes on PC Cards
 Some PC Cards require that you disable idle devices when using the PC Card. You can use Sony Notebook
Setup to disable devices. See
Displaying the Sony Notebook Setup Screen for more information.
 Make sure you use the most recent software driver provided by the PC Card manufacturer.
 If an exclamation mark (!) appears on the Device Manager tab in the System Properties dialog box, remove
the software driver then reinstall it.
 For some PC Cards, if you alternate between normal power operation and the Standby or Hibernate power
management modes while the card is inserted, you may find that a device connected to your system is not
recognized. Reboot your system to correct the problem.
 See the manual that came with your PC Card for more information on its use.
