There is noise when I am listening to music through USB speakers/headphones

To stop the noise, proceed as follows:

1Right-click the CPU icon in the system tray and click Edit/Create Profiles… from the menu. The Profile Editor window appears.

2Double-click CPU Control – Performance (or Adaptive or Battery Life) on the right of the screen. The CPU Control list appears with a check mark on the current setting.

3Click Performance or Battery Life.

Select Performance if you use applications that take much of the CPU.

4From the File menu, click Save.

5From the File menu, click Exit.
