Most ExpressCard problems occur during installation and setup of new cards. If you are having trouble getting one or more of these devices to work together, several sections in this chapter may apply. If your system does not have built-in drivers for your ExpressCard and the card did not come with an operating system driver, it may not work under the operating system. Contact the manufacturer of the ExpressCard for information about using the card under the operating system. ExpressCard® checklist ❖ Make sure the card is inserted properly into the slot. ❖ Make sure all cables are securely connected. ❖ Occasionally a defective ExpressCard®slips through quality control. If another computer with a ExpressCard slot is available, try the card in that machine. If the card malfunctions again, it may be defective.
