Troubleshooting Your Computer
Reference Guide 107
If sound does not record
•
Check the software controls for recording sound: click Start, Programs (or All
Programs), Accessories, Multimedia (or Entertainment), Sound Recorder.
•
In Volume Control, click Options, Properties, and make sure the microphone is
enabled in the recording controls.
•
Test the audio with the e-Diagtools diagnostics—see “Testing the Hardware” on
page 129.
If you hear a loud high-pitched whine (feedback) from the speakers
•
In the Volume Control, try reducing the Master volume: double-click the speaker icon
in the taskbar.
•
In Volume Control, click Options, Properties, and select the microphone option for
the playback settings. Then in Volume Control, make sure the microphone is muted.
•
Avoid using the built-in microphone and built-in speakers at the same time.
CD and DVD problems
If you can’t boot from a CD or DVD in the CD/DVD drive
•
Make sure the CD or DVD is bootable, such as the Recovery CD .
•
Make sure the CD-ROM/DVD drive is selected as the boot device—see “To change
the boot device” on page 32.
•
Restart the computer: click Start, Shut Down (or Turn Off Computer), Restart.
•
Test the CD/DVD drive with the e-Diagtools diagnostics—see “Testing the
Hardware” on page 129.
If a DVD plays erratically
•
Dirt or smudges can cause a disc to skip. Clean the disc with a soft cloth. If the disc is
badly scratched, it will probably have to be replaced.
•
If you’re playing the DVD on battery power, try changing the power scheme. See the
hint under “To play DVD movies” on page 86.
•
Some DVDs include software called “PC Friendly.” You generally should not install
this software, as it can cause errors or erratic play. If needed, uninstall it and restart
your system.
