If Something Goes Wrong
Resolving a hardware conflict
The computer emits a loud, high-pitched noise.
This is feedback between the microphone and the speakers. It
occurs in any sound system when input from a microphone is fed to
the speakers and the speaker volume is too loud. Adjust the volume
control.
ExpressCard™ problems
(ExpressCard slot available on certain models)
ExpressCards™ (PCMCIA-compatible) 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.
Resource conflicts can cause problems when using ExpressCards.
See “Resolving a hardware conflict” on page 170.
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 an ExpressCard slot is
available, try the card in that machine. If the card malfunctions
again, it may be defective.
