Solution
Inspect all cables and connections.
Check whether your PC Card is fully inserted into the slot.
Verify that you have the latest BIOS for your system. If not,
check the Web site for your computer and follow the BIOS
upgrade instructions.
Check for multiple installations of the PC Card.
Check whether your system's PCMCIA or CardBus Controller
is installed and running properly: go to My Computer/Control
Panel/System/Device Manager/PCMCIA Card. Verify that the
controller is present and shows no errors.
Open My Computer/Control Panel/PC Card to confirm that the
system recognizes your PC Card.
In My Computer/Control Panel/Network make sure that you
have the correct clients and protocols installed.
Use My Computer/Control Panel/System/Device Manager to
inspect the status of your PC Card.
If you see a red "X", enable the PC Card by checking the
appropriate box under Properties.
If you see a yellow exclamation mark, click the icon to see
what the conflict is. Verify that there are adequate system
resources. Free system resources (for example, disable the
infrared port), remove and reinstall the PC Card.
