What should I do if I do not hear sound from the built-in speakers?
❑ If you are using a program that has its own volume control, make sure the volume control is properly set. See the
program's help file for more information.
❑ The volume may have been turned off by the Fn+F2 keys. Press them once again.
❑ The volume may have been minimized by the Fn+F3 keys. Keep pressing the Fn+F4 keys to turn up the volume loud
enough to hear sound.
❑ Check the Windows volume controls by clicking the volume icon on the taskbar.
