Resolving a hardware conflict
Sound system problems
No sound is coming from the computer’s speakers.
Adjust the volume control.
Try pressing
Fn + Esc
to see if volume mute is disabled.
Check that the volume control on the computer is turned up.
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 180
.
If your system does not have built-in drivers for your PC Card and
the card did not come with an operating system driver, it may not
work under the operating system. Contact the manufacturer of the
PC Card for information about using the card under the operating
system.
PC Card checklist
❖
Make sure the card is inserted properly into the slot.
❖
Make sure all cables are securely connected.
❖
Occasionally a defective PC Card slips through quality control.
If another computer with a PC Card slot is available, try the
card in that machine. If the card malfunctions again, it may be
defective.
