I have a new laptop, Inspiron 15 5000 series and the shortcut keys (F1 - mute, F2 - lower volume., F3 - increase volume) do not work.  I have to go to the arrow in the lower right hand corner that shows the volume control to adjust the volume.  I have updated and install updated drivers and that did not work either.  I have a Windows 10 operating system.

Please help!

Thank you,

Katy
