My laptop has an open port has a symbol underneath it that looks mostly like this:
{.....
} (the dots are a little higher -- in the middle).
Does anyone know what that symbol means? All the other ports are obvious -- monitor, printer, headphones et cetera but this one is a mystery. I'd like to plug a keyboard into it but it doesn't have a port for that. Just this mysterious thing that will not accomodate a keyboard wire.
