Hey JoJo, you didn't say what model Acer laptop you have, or the operating system you are running. I have an Aspire V5-571G, about 6 months old, and to adjust the sound volume, hold the function key (Fn) down, lefthand side of keyboard, and then press the up/down arrow keys, right hand side of keyboard.That is the basic method. Hope that helps. Oh yes, also check your manual. Most of us don't. lol.
Member RevoMaxx is quickly moving up the ranks of Acer Community. He joined us in September and is already making a difference. It's great to see new members like him make a difference only after a few months. Thanks RevoMaxx!
