Sound system problems
You do not hear any sound from the computer.
Adjust the volume control.
Try pressing
Fn + Esc to see if volume mute is disabled.
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.
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 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 PC Cards.
See “Resolving a hardware conflict” on page 220.
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.
