ExpressCards

®

 include many types of devices, such as a removable 

hard disk, additional memory, or a pager.

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.

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.
