How do I turn the sound on my laptaop back on?

ok usually laptops have this button on the keyboard tht says Fn ok now after uve found tht there should be another symbol thing on top of another smbol thing but its different on evey lap top so i cant tell u exacty where it is but 4 example mine is on top where the F1 F2 etc. are the symbol is little speakers and when u press the Fn while pressing tht button the speakers should turn on

If you are working with a microsoft program - go to the start menu, click onto settings, then click on the control panel, then click on sounds and audio - you should be able to figure it out from there.
