Sound system problems
You do not hear any sound from the computer.
Adjust the volume control.
If you are using external headphones or speakers, check that they
are securely connected to your computer.
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.
Changing the settings for the Record Monitor feature in the
Recording Control Utility (default Off), or the Mute feature in the
Mixer Utility (default Enabled), may cause feedback. Revert to the
default settings.
PC Card problems
PC Cards (PCMCIA-compatible) include many types of devices,
such as a removable hard disk, additional memory, or a pager.
Most PC Card problems occur during installation and setup of
new cards. If you're 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 PC Cards. See
"Using PC Cards" on page 103
Card Information Structure
When you insert a PC Card into a slot, the computer attempts to
determine the type of card and the resources it requires by reading
its Card Information Structure (CIS). Sometimes the CIS contains
enough information for you to use the card immediately.
