Sound system problems
Sound system problems
No sound is coming from the computer’s
speakers.
Adjust the volume control.
Try pressing the Fn + ESC key 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.
ExpressCard® problems
(Available on certain models.)
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.
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 a ExpressCard®
slot is available, try the card in that machine. If the card
malfunctions again, it may be defective.
