Your speakers may be set to mute, the volume setting may be too low, or the
audio option may be disabled. See “Adjusting the volume” and “Enabling
the audio feature” for more information.
Why don’t the Fn+F3 or the Fn+F4 key combinations work?
The computer may not recognize the Fn+F3 and Fn+F4 key combinations if the
correct speakers are not selected. Follow these steps:

Right-click the Volume icon
on the taskbar, and select Adjust Audio
Properties.

Select the Audio tab, and click Advanced in the Sound Playback box. The
Advanced Audio Properties window appears.
3
Click the Speakers tab, if it is not already selected.
4
Select the correct stereo speakers from the Speaker setup drop-down menu.
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 are using a memory-intensive program, set the CPU to
Performance.
*
Follow these steps:
1
Right-click the CPU icon
on the Windows® taskbar, and click
Edit/Create Profiles. The Profile Editor window appears.
2
In the left panel, click the power management profile that you want to set.
Maximum Battery Life is the default selection when your computer is
running on battery power.
3
In the right panel, double-click either CPU Control (Plugged in) or CPU
Control (Running on batteries), depending on the power source you are
using. A menu of CPU Control options appears.
4
Select an option. If you are using a memory-intensive program, set the CPU
control to Performance.
5
Click the File menu, and click Save.
