Some PC Cards may require you to disable idle devices when using the PC Card. You can use Sony Notebook Setup to disable devices.
Be sure to use the most recent software driver provided by the PC Card manufacturer.
If an “!” mark appears on the Device Manager tab in the System Properties dialog, remove the software driver and then reinstall it.
You do not need to shut down the computer before inserting or removing a PC Card.
Do not force a card into the slot. It may damage the connector pins. If you have difficulty inserting a card, check that you are inserting the card in the
correct direction. See the manual supplied with your PC Card for more information on use.
For some PC Cards, if you alternate between normal power operation and the system suspend or system hibernation 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.
