5.2 Troubleshooting Audio Problems

Problem: No sound from the integrated speakers.
Troubleshooting and problem resolution:
• Adjust the Windows volume control — double-click the speaker icon in the
lower-right corner of your screen. Ensure that the volume is turned up and the
sound is not muted. Adjust the volume, bass, or treble controls to eliminate
distortion.
• Reinstall the audio driver.
• Disconnect any headphones from the headphone connector — sound from
the speakers is automatically disabled when headphones are connected to the
computer's side-panel headphone connector.
Problem: No sound from headphones.
Troubleshooting and problem resolution:
• Check the headphone cable connection — ensure that the headphone cable is
securely inserted into the headphone connector.
• Adjust the Windows volume control — click or double-click the speaker icon in
the lower-right corner of your screen. Ensure that the volume is turned up and
the sound is not muted.
5.3 Troubleshooting Software Problems
Problem: You are unable to exit a running program normally.
Troubleshooting and problem resolution:
1. Open the Task Manager window by pressing Ctrl, Alt and Delete at the same
time.
2. Select the Application tab, select the problem program, then click the End
Task button.
Problem: You need to install or uninstall a program.
Problem resolution:
During installation never abort the install process by powering the system off or
through other drastic means. This can cause system program problems or even
failure during system initialization.
