One of the important features of a portable computer is the credit card-like PCMCIA cards, also known as PC Cards. The process for troubleshooting PC Cards is very much identical to troubleshooting other I/O adapter cards.
To check that the PC Card device is working properly, access Device Manager. Incase there is a problem with the PC Card device, it appears in Device Manager. If the PCMCIA adapter's icon shows an exclamation mark on a yellow background, it indicates that the card is not functioning properly. Turn the system off and reinsert the device in a different PCMCIA slot. If the same problem persists, three possible sources of problems exist-the card might be faulty, the PC Card controller in the PC might be faulty, or the operating system might not support the device in question.
