Today I turned on my laptop and the speaker icon had disappeared. Since I was listening with my headphones on last night the volume was quite high but since the icon was not there I couldn't turn it down. No amount of going through menus and help tips would bring it back. What to do? I thought back over all the advice I have ever received from IT professional and quickly came to a solution. What did I do? Simple - I turned it off and on again and guess what, the icon was back and everything worked again. Does this mean I'm a computer expert now.
