Why do I hear noise distortion while listening to music with speakers or
headphones?
You may experience noise distortion while listening to music with speakers or
headphones if the CPU control is set to Automatic Profile Selection. Use the
preinstalled PowerPanel™ software to set the CPU control to Performance or
Battery Life. If you use a memory-intensive application, set the CPU to
Performance.
