Troubleshooting Techniques
This section contains solutions to a few common problems and troubleshooting
techniques for your HP notebook PC.
Audio problems
If sound is not audible
• Press Fn+Up arrow several times.
• Click the speaker icon on the taskbar to ensure that Mute is not checked.
• When you are operating your computer in MS-DOS mode (for example, when
running MS-DOS games), you may find that the sound does not operate properly.
Use Windows applications for full use of sound capabilities.
If sound does not record
• Check software controls for recording sound: Click Start, Programs, Accessories,
Multimedia (or Entertainment), Sound Recorder.
If the PC card detection beep(s) at startup are very loud and volume cannot be
adjusted
• Download the latest audio driver from the technical support area of the HP notebook
website (http://www.hp.com/notebooks).
You may also want to test the audio with diagnostics. See “Testing Hardware Operation.”
CD-ROM drive problems
If you can’t boot from a CD in the CD-ROM drive
• Make sure the CD is a bootable CD, such as the Recovery CD.
• If you always want to boot from a CD when one is present, check the boot order in
BIOS Setup and change it.
1. Click Start, Shut Down, Restart.
2. When you see the HP logo, press Esc to open the Boot menu. The default boot
order is (1) Floppy Drive, (2) Hard Drive, and (3) CD-ROM/DVD Drive.
