How do I get my computer out of quiet office mode?

[Suengmina]

I have an asus laptop running Windows 7. Last night, I hit a key accidentally and it switched into something called quiet office mode. I've looked around and can't find a way to switch it back, I've tried hitting all the keys in the area I think I accidentally hit to turn it on, and I've searched around for a solution both on the computer's help guide and the internet but I couldn't find anything. Please don't bother responding to say "hit the key again" since I'm not sure which key made it happen. Thank you so much.

that just happened to me, and you have to press fn and space bar until you get to entertainment mode or w/e mode you're usually in
